.300 Weatherby Information

by Woodsbum

Today I ran across an interesting article on the .300 Weatherby. For many years I have used mine mainly for elk and even reload for it. The rifle and cartridge has worked well for me once I got it all dialed in with a solid load. Recently I was able to get everything figured out where I am hitting the same spot time after time at 100 yards (of course strapped to a lead sled) with some 180 grain bullet loads. The truth is that I am now quite fond of both the rifle and the cartridge.

Unfortunately, there has been a lot of “bad press” about this cartridge due to people not representing the calibre correctly. Many misconceptions are out there about where this load fits in the whole scheme of things. This article really gives great information on the .300 Weatherby and explains where it might fit into your rifle collection.

.300 Weatherby Magnum

History

 
Based on the .300 H&H case blown out to maximum capacity, the .300 Weatherby Magnum was introduced by Roy Weatherby in 1944. Although the case design of the Weatherby was entirely different from the .300 H&H, enabling head spacing at the shoulder, Weatherby retained the belt at the case head, resulting in a very successful marketing ploy. The .300 Weatherby became the most popular cartridge of the Weatherby line and historically, is responsible for initiating the general trend towards ultra velocity cartridges. 
 
In 1963 Winchester released their .300 Winchester magnum as competition to the Weatherby cartridge.  The Winchester offering had two major advantages, inexpensive factory ammunition along with plainer, more utilitarian rifles as opposed to the Weatherby rifles which at this time, were often considered somewhat garish in appearance by many shooters. The Winchester cartridge and rifles appealed to more reserved hunters, the Weatherby to those that favored extreme velocities. Although the .300 Winchester Magnum became a major worldwide success, it took only a small share of Weatherby’s market, each style of rifle and cartridge appealing to different customers.
 
Today, the Weatherby remains popular as a medium game hunting cartridge but has come into its own as a long range hunting cartridge, utilized in both both factory and custom rifles. One could say that in this regard, the .300 Weatherby was 50 years ahead of its time as it has only been recently that suitable optics and range finders for long range hunting have been available to the public at affordable prices.
 

Performance

The .300 Weatherby Magnum is a truly powerful, highly effective medium game cartridge. This cartridge has however always suffered one major limitation – unrealistic expectations. In earlier years the Weatherby was promoted as being able to flatten anything that walked via sheer velocity. Extreme advocates of the .300 Weatherby have over the years made strongly convincing statements of this cartridges ability to cause such wounding that animals may be “blown in half” and that accordingly, shot placement when using the Weatherby is of low priority. Unfortunately, in many instances, the factors of bullet construction and precise shot placement were abandoned in favor of fantastical reasoning. 
 
In Africa, guides shuddered at yet another client toting a .300 Weatherby, another potential bullet blow up, a failed or slow kill resulting in hours of tracking and hard labor. In the South Island of New Zealand, shots would have to be taken at 300-400 yards, a challenge in the days before high power optics, range finders and drop charts. NZ guides would watch as shot after shot went down range at the nimble Thar and Chamois, the hit rate was low, gut shots were common. The term ‘Weatherby eyebrow’ also became common, a problem associated with short eye relief scopes on high recoiling rifles. Clients often had more of a chance of wounding themselves than their intended target. North American guides and Canadian guides had exactly the same experiences. All of this gave the .300 Weatherby a bad reputation which stuck for decades.
 
The strengths of the .300 Weatherby lie in its ability to produce effective killing on a wide variety of game species and body weights, out to ranges well beyond 1100 yards (1km). However, the .300 Weatherby cannot do all of these things with a single load, nor can it shoot itself. 
 
The .300 Weatherby Magnum can only be exploited through accuracy combined with appropriate projectiles for the job at hand. .300 Weatherby shooters must learn to be able to differentiate between rifle accuracy problems and shooter error. Practice is key if any level of proficiency is to be obtained. In platforms which induce intolerable or uncontrollable recoil, a muzzle brake should be fitted to aid accuracy.
 
Choice of optics for .300 Weatherby rifles is also very important in order to avoid the dreaded Weatherby eyebrow (scope cuts to the eyebrow) and the flinch that develops both before and after injury. Short eye relief scopes should be avoided and shooters need to understand that short eye relief scopes can be found within most brands (including high end optics such as Zeiss and Swarovski). When selecting a scope, the shooter must observe ‘models’ rather than brands to obtain correct eye relief information. Appropriate scope eye relief for the .300 Weatherby (actually all of the .300 Magnum family) unbraked is 4”.  
 
Loaded with 150 grain bullets, the .300 Weatherby is a spectacular killer of lighter medium game. Penetration can occasionally be somewhat poor with conventional projectiles when used at closer ranges on large bodied animals. In general, on light game weighing 40 to 60kg (up to 130lb) 150gr conventional or  premium bullets driven at 3450fps produce a wound channel through vitals of between 2 and 3” in diameter, resulting in exit wounds of the same diameter, when used at close to moderate ranges. On game weighing between 60 and 90kg (130-200lb), internal wounds may be 2-3” in diameter, however 150 grain conventional bullets may or may not exit depending on bullet construction and bone encountered. Premium 150 grain bullets such as the Nosler Partition, Scirocco and InterBond will in most instances exit, rendering a 1.5 to 2” exit wound. A 150gr bullet does provide some room for error when matched appropriately to game weights. 
 
In the .308 Win and .30-06, traditional 165 grain hunting bullets quite often produce clean but delayed killing on light framed game. Accordingly, one might expect that the velocities of the Weatherby would ensure more emphatic results. Unfortunately, this does not prove true, at least not in a uniform and predictable manner, especially at extended ranges where cartridge performance overlaps. While some bullet designs such as the 165 grain SST can prove to be spectacular killers of light framed or lean game, often the results are the same as those derived from the .308 Win and .30-06. Again, the 165 grain bullet weight proves its merit when used on medium body weights of between 80 and 150kg (180-330lb). Such results also help us understand that the immense power of the Weatherby is best utilized as a means to obtain fast killing at extend ranges, not increase killing power within ordinary hunting ranges (300 yards).  As stated however, there are exceptions, the Hornady 165 grain SST is immensely and positively responsive to increased velocities.
 
Loaded with 180 grain bullets the Weatherby is an emphatic killer of larger bodied medium game out to generous ranges. The Weatherby places great stress on projectiles, demanding that bullet construction be matched to game weights in order to avoid erratic or unexpected disappointing results. On game weights of between 90 and 300kg (200-700lb) wound channels produced by appropriate 180gr bullets driven at 3250fps tend to be around 1.5 to 2” in diameter. Conventional 180gr projectiles produce similar sized wounds to premium 180gr bullets but at Weatherby velocities are extremely prone to gradual and total disintergration, rapidly decreasing the depth of wounding at close ranges.
 
Many 180gr to 200gr .30 caliber bullets driven at Weatherby velocities are close to ideal for use on Elk simply because the thickness of the shoulder corresponds with the distance traveled before many 180 to 200gr bullets (both conventional and premium) reach full wounding potential. The width of an Elk chest corresponds with the distance most 180 and 200gr bullets travel while creating the broadest part of their wound channel.  The wound channel gradually tapers to a size not much bigger than the mushroomed projectile as it comes to rest or departs the skin of the offside shoulder. 
 
When enough resistance is met, 180 to 200 grain bullets may bore an internal wound through vitals of approximately 2 to 3” in diameter. On lighter game however; wounding with 180-210 grain bullets tends to be much smaller, around 1”, with little or no hydrostatic shock, greatly decreasing room for error, regardless of muzzle velocities or range. At longer ranges where velocities approach those of the .308 Winchester (around 300 yards), room for error drops substantially and accurate shot placement is paramount. Rifles that cannot shoot 1 MOA or less at 100 yards may cause slow killing and in precipitous country this often results in the frustration of an un-retrievable animal that has tried to escape into safe inaccessible terrain but died in the process.
 
Loaded with 200-220 grain bullets, the .300 Weatherby can be utilized to great effect on very large game. Again, bullet construction is of immense importance when using the Weatherby on tough game. On game such as Grizzly bear, the heavy Swift A-Frame and Woodleigh bullets are bread and butter, producing highly traumatic wounding and deep penetration for fast, clean and humane killing. On truly heavy game, the .30 calibers, regardless of muzzle velocity, lack the ability to produce deep broad wounding with ordinary cross body shots. On heavy game, neck and head shots with premium projectiles produce emphatic results.
 
Loaded with heavy, frangible, high BC projectiles, the .300 Weatherby is an excellent long range hunting cartridge filling a game performance niche that no other cartridge apart from the .300 Dakota fills. Case capacity of the Weatherby is about as large as this bore diameter can handle (gas expansion) without going overboard towards the realms of extreme bullet jump and severely shortened barrel life. While the freebore of the Weatherby is long, the equally long case neck acts as a reliable guide, having more in its favor than the .308 Winchester freebore design. Loaded with heavy frangible bullets, the Weatherby can be expected to produce fast killing on a wide variety of body weights out to ranges exceeding 1100 yards.
 
The strengths of the .300 Weatherby (and .300 Magnum family) can be found when used on game weighing between 90 and 320kg (200-700lb) at ranges of 300 yards and beyond, achieving results that cannot be found in the sevens and smaller calibers, regardless of down range trajectories. The trade off is recoil. The .300 Weatherby produces a level of recoil that must be tamed through either design and technology or technique and personal discipline, in order to obtain optimum results.
 
 

Factory Ammunition

Light weight loads from Weatherby include the 130 grain Barnes TTSX at 3650fps, the 150 grain Hornady soft point Interlock and the 150 grain Nosler Partition at 3540fps (26” barrels). Due to the twist rate of 1:10 utilized in Weatherby factory rifles for optimum accuracy with heavy bullets, while some rifles may produce excellent accuracy with 130-150 grain bullets, results vary.
 
The 130 grain TTSX bullet is a relatively new offering from Weatherby and although its weight may seem negligible, 130 grains is about perfect for a homogenous .30 caliber bullet for use on light through to medium weight antelope and deer species along with wild boar. This load is perfectly adequate for tackling game weighing up to 150kg (330lb), rendering broad internal wounding for fast killing, yet often showing minimal meat damage as velocities fall below 3000fps. The 130 grain TTSX does its best work at impact velocities above 2200fps or approximately 500 yards.  
 
The 150 grain Hornady Interlock is best suited to light game under conditions where raking shots do not have to be taken at close ranges, producing best results between the ranges of 125 and 425 yards.  Beyond 425 yards, wind drift starts to become a problem for the Interlock (and Partition). The 150gr Partition is an excellent projectile for use on game weighing up to 100kg (220lb) and at ranges beyond 125 yards, is adequate for game weighing up to 150kg. If the 150 grain Partition is pushed too hard, such as on large tough animals at close ranges, there is a small risk of jacket / rear core separation. The Partition is a stellar performer, producing wide, violent wounding for fast killing but hunters must be realistic about limitations. Sectional density versus game weights must always be taken into consideration when using the Partition. The 150 grain Partition produces excellent wounding down to velocities of 1800fps (750 yards) however wind drift is a major limiting factor.

Weatherby currently list three 165 grain loads including the Interlock (flat base) at 3390fps, the 165 grain Ballistic SilverTip at 3350fps and the 165 grain Barnes TSX at 3330fps. The 165 grain Hornady projectile has a much softer jacket than the Ballistic SilverTip. Best suited to game weighing up to 90kg if used at woods ranges, the Interlock produces its most uniform results on game weighing between 80 and 150kg (180-330lb) at impact velocities of between 3100 and 2200fps (between 100 and 500 yards) though still showing vivid expansion at 2000fps. This is a good, fast killing load, suitable for a vast range of deer species and should not be overlooked.
 
The 165 grain BST is a flat shooting projectile with a BC of .475 as opposed to .387 for the Interlock. However; as ranges are increased, the BST can produce delayed killing (regardless of excellent wounding) on lean game (under 90kg/180lb) with rear lung shots. In contrast, the Hornady bullet would have produced slightly delayed killing, rather than a long ‘dead run’. Both of these 165 grain bullets are immensely useful but there is a definite requirement to match game weights to bullet construction. The subtleties of this can be difficult to explain. For example, the BST is frangible at close ranges but the slight delay (perhaps only .5” of penetration) can inhibit hydrostatic shock transfer (see game killing text) via the ribs to the spine and through to the brain. So while internal wounding can be broad, lean game may run, in some cases being lost in ravines (a curse of alpine hunters). As body weights increase slightly, tipping my often quoted 90kg (180lb) mark, the target resistance is matched to bullet expansion, resulting in very emphatic killing.
 
Weatherby’s tough 165 grain TSX load has its strengths, suitable for game weighing between 90 and 320kg (180-700lb). On large animals, especially at impact velocities below 2600fps, hydrostatic shock can be non-existent and wounding can be a little narrow. Again, best results are obtained by matching body weights to bullet construction.
 
Weatherby 180 grain offerings include the Hornady Interlock (flat base) at 3240fps, the BST at 3250fps, the Partition at 3240fps, the Accubond at 3250fps and the 180gr Barnes TSX at 3240fps. Weatherby’s 180 grain loads are best suited to game weighing above 90kg (180lb). The five loads offer varying rates of expansion, suitable for a wide variety or game weights of up to 450kg (180-1000lb). 
 
The 180 grain Interlock and BST loads are, like the 165 grain loads, best suited to game weighing between 90 and 150kg but at extended ranges of around 300 yards and beyond, can be very emphatic on game weighing up to 320kg (700lb). Put simply, increasing range increases bullet performance on larger bodied animals.
 
The 180 grain Partition is a versatile bullet, rendering deep, broad wounding on game weighing up to 320kg (700lb) and is about ideal for Elk. From a muzzle velocity of 3240fps, the Partition can be expected to produce deep, broad wounding down to 1800fps or 780 yards. The Partition can be asked to tackle larger body weights of up to 450kg (1000lb) but not at woods ranges with ordinary chest shots due to the risk of jacket / rear core separation should the Partition strike ball joints. As with all of the .30’s, on heavy game, neck and head shots ensure emphatic results, minimizing incidents of insufficient penetration (such as the close range/ball joint example). At longer ranges, the Partition shows adequate penetration on heavy game but, due to the limitations of the bore diameter, can produce narrow lung wounding (proportionate to game weights). As always, readers are advised to study and record autopsy results, take photo’s, monitor wounding and penetration in order to provide sound conclusions.
 
Weatherby’s 180 grain Accubond load is ideally suited to game weighing between 90 and 320kg out to ranges of around 575 yards. Somewhat of an oddity, the Accubond will often produce delayed kills on lean game due to the slightest delay in expansion (minimal target resistance) yet at the other extreme, when the Accubond encounters too much body weight, it suffers severely limited penetration and wounding. This is one of many projectiles that are about ideal for ridge to ridge shooting of Red deer, Mule Deer, Caribou, Himalayan Thar and at the upper end, Elk.
 
For tough game, the 180 grain Barnes TSX at 3240fps is a good performer. It is definitely true that the faster the Barnes is driven, the better, working well with the Weatherby ethos. Ideally suited to game weighing above 150kg (330lb), the TSX produces violent wounding for fast killing out to ranges of around 300 yards, steadily declining in wounding potential thereafter. On truly large heavy game, the 30 caliber TSX can produce narrow wounding, regardless of full cross body penetration. Again, this is a limitation of the bore diameter, not the bullet design.
 
Weatherby list two heavy loads, the 200gr Partition at 3060fps and the 220gr Hornady round nose bullet at 2845fps. The 200 grain Partition is a very versatile bullet, boasting an excellent balance of high SD versus high velocity, versus fast expansion, essentially ticking all of the boxes. Yet still, this load does not make the .300 Weatherby ideal water buffalo medicine. Great strengths combined with realistic expectations are the key. This load is very well suited to North America and Canada’s large game species, at both close ranges as well as long ranges of up to 700 yards or so (1800fps). Deep, violent, highly traumatic wounding are hall marks of the 200 grain Partition driven at high velocity. Weatherby’s heaviest load, the 220 grain Interlock is unfortunately, a lack luster performer on large animals. This is an extremely soft jacketed projectile, more suited to game weighing up to 150kg (330lb) at woods ranges. Used this way, the 220 grain Interlock load displays great strengths.
 
Remington currently list one load for the Weatherby, the 180gr Core-Lokt at 3120fps. The economical Core-Lokt is an excellent 90 to 180kg (200-400lb) game bullet and is less prone to blow up than the 180gr Interlock, also producing adequate performance on large body weights of up to 320kg (700lb) as velocities fall below 2800fps (125 yards). The Core-Lokt has a low BC of .383, losing velocity rapidly and suffering wind drift accordingly, producing best performance inside 400 yards.
 
Federal currently list three180gr loads for the Weatherby, the 180 grain Partition at 3190fps, the 180gr Trophy Bonded Bear Claw (now featuring a polymer tip) at 3100fps and the 180 grain TSX at 3110. As has already been described, the Nosler partition is an excellent projectile, about ideal for Elk. The TTBBC offers a unique level of performance that cannot be under-estimated. This projectile has the ability to render heavy trauma throughout penetration, producing emphatic and ‘safe’ kills on tough game. The TTBC has a BC of .480, not exceptionally high but great enough to deliver immense trauma out to a range of 250 yards, retaining good performance out at 350 yards (2400fps). Below 2400fps, wounding gradually becomes narrower, more so and especially at 2200fps and below. It is odd that Federal list the TSX alongside the TTBBC loading, overlapping performance. A frangible long range projectile such as the Speer 180 grain BTSP would add more versatility to the Federal line up.  
 

Hand Loading

As a hand loading proposition the .300 Weatherby has had a somewhat jaded past. Most hand loaders and powder manufacturers working up loads in the Weatherby, from the 1950’s through to the 1980’s, were either unable or unwilling to try and achieve Weatherby’s advertised velocities and instead, loads duplicated what hand loaders were already achieving in the .300 Win mag with figures of 3300 and 3070-3100fps with 150 and 180gr bullets respectively. Throat lengths also tended to vary from the generous free bore of the Mark V rifle to short throated designs, created towards a goal of optimum accuracy. It was also very common for hunters to dock the 26” barreled Mk V to 24” to make the rifles more portable. The Weatherby needs a 26” barrel, not just for velocity but also to keep weight, noise and muzzle blast forwards. Longer barrel lengths also show great strengths in these areas.
 
From a Factory standard 26” barrel, realistic velocities for the .300 Weatherby include 3450fps with 150gr bullets, 3300fps with 165-168gr bullets, 3250fps with 178-180gr bullets, 3150fps with 190 grain bullets, 3050fps with 200 grain bullets, 3000fps with 210 grain match bullets and 2900fps with 220 grain bullets. Individual rifles can achieve higher velocities than the above stated figures. In half throated custom barrels, velocity loss is in the order of 100fps, though again, individual rifles vary.
 
Twist rate of the .300 Weatherby is as mentioned, typically 1:10, ideal for bullet weights of 165 grains and heavier. In such instances where a light, fast expanding bullet is desired but accuracy is poor, bullet designs like the Hornady 178 grain A-Max are capable of achieving optimum results on light game.
 
Rather than continually reiterating bullet performance at magnum velocities, the section ahead will focus on some of the more effective projectiles that allow the .300 Weatherby to truly shine.
 
Of the Hornady bullet range, the light 150 grain SST and Interbond can be used to great effect on lighter game. The one limitation with the 150 grain SST, is that at close ranges where velocity is high, the projectile can sometimes meet too much resistance (water surface tension), failing to impart hydrostatic shock. On light framed game, regardless of whether bullet blow up occurs (due to ultra velocities), wounding through vitals is always thorough. The negative aspect of the SST is more to do with expectations than anything else, the disappointment of slightly delayed killing. The 150 grain Interbond does not produce this type of reaction at close ranges and, where these odd instances of hydrostatic shock failure do occur, the two projectiles can be used together, the InterBond for very close range work while being equally good out to ranges of around 350 yards, the SST coming into its own at 3200fps (after 100 yards).
 
The 165 grain Hornady SST driven at 3300fps is a violent, emphatic killer of medium game, a generally exceptional deer bullet. Again, this 165 grain bullet does its best work on game weighing between 80 and 150kg (180-330lb) with one caveat, by keeping the SST above 2400fps out to a range of 425 yards, speed of killing is increased on very light framed game where rear lung shots are taken. This makes for a very versatile, effective and emphatic deer bullet in the Weatherby. Along with this, the 165 grain Interbond can be partnered with the SST and used to great effect on body weights of 90-200kg (200-330lb), giving best performance out to the same quoted range of 425 yards.
 
Expectations are key when using the 180 grain SST on game in the Weatherby. When used at ordinary hunting ranges, this projectile does its very best work on game in the 80 to 150kg range, just the same as the 165 grain SST. The 180 grain SST can also be a spectacular killer of light framed game at impact velocities above 2600fps. If the 180 grain SST is used at ranges of 50-100 yards on game weighing 80-150kg, killing is fast and emphatic, yet penetration is often less than expected, the projectile coming to rest against offside skin. As velocity falls, performance is enhanced, wounding on raking shots is deeper, though the ogive of the 180 grain SST should be annealed (rotated) in candle flame for best results. On deer/antelope species weighing around 320kg (700lb), the 180 grain SST gives best performance between the velocity parameters of 2600 and 1600fps or approximately 300-950 yards. The tough 180 grain InterBond is as can be expected, an emphatic killer of large bodied deer out to moderate ranges. 
 
Hornady’s 178 grain A-Max can be used not just as a long range bullet, but as an alternative to the 150 grain bullet for use on light game. The 178 grain A-Max is an excellent performer on lighter body weights but on game weighing 90kg and heavier, is much more effective at longer ranges. Generally speaking, the 7mm and .30 caliber A-Max projectiles display best penetration at impact velocities of 2600fps and below.  On tough game, there is a marked decrease in penetration at impact velocities of above 2900fps.
 
As a long range hunting cartridge, the .300 Weatherby loaded with the 208 grain A-Max is a powerhouse. The 208 grain bullet produces immensely traumatic wounding right down to the typical 1400fps that is often quoted within this research. At low velocities, frontal shots on light framed game should be avoided, simply due to the wastage of the entire carcass. From a muzzle velocity of 3000fps (some rifles achieve higher velocities), the 208 grain A-Max travels around 1325 yards before breaking the 1400fps, reaching the sound barrier (standard atmospheric model) at a whopping 1730 yards. The 208 grain A-Max is ideal for a vast range of game, reaching its practical limits on Elk.
 
Speer’s traditional Hotcor and BTSP projectiles can be very useful in the Weatherby. The 150 grain Hotcor is a spectacular killer of light game within ordinary hunting ranges. The 150 grain BTSP is however, much too soft, if close range shots are encountered. The middle weight 165 grain Hotcor and BTSP both show great strengths, again on the body weights of 80-150kg (180-330lb). The 180 grain Hotcor, though so very basic in its design, is a hard hitting bullet, ideal for large bodied deer. The soft, highly frangible 180 grain BTSP also has great strengths and with its high BC of .545, can be used out to very long ranges. This is a bullet that excels on game weighing between 90-180kg (200-400lb) out to ranges of 900 yards (1800fps), continuing to produce adequate wounding on suitable body weights, as velocities fall to 1600fps. The 200 grain Speer Hotcor is a wonderful projectile, hard hitting and clean killing, ideal for large bodied deer and especially useful for woods hunting. BC of the 200 grain Hotcor is .478, delivering highly traumatic wounding out to ranges of around 350 yards.
 
As discussed in the factory ammunition section, the Nosler Partition projectiles are excellent performers producing fast, violent expansion down to 1800fps, along with excellent penetration. In many instances, performance is more spectacular and more uniform that either the Ballistic Tip or Accubond bullet designs. That said, the 150 grain Accubond produces outstanding results on light game, out to ranges of around 400 yards. The 180 grain Accubond is a stellar performer on larger bodied deer but on deer species weighing around 320kg (700lb), the 200 grain Accubond really comes into its own in the .300 Weatherby. The heavy Accubond is, like its kin, prone to shed as much as 50% of its weight after impact but offers a high BC, fast expansion, broad wounding and desirable penetration. This is an excellent cross valley hunting bullet.
 
Nosler’s 180 and 200 grain Partition bullets show great strengths on Elk sized game, but cannot be expected to produce entirely uniform results with chest shots on heavy game where the foreleg bones are 3” in diameter and the ball joints are of 5” in diameter or larger. The heaviest of the Partitions is the 220 grain semi point, capable of excellent penetration, again, not ideal for bovine sized game with chest shots but certainly effective on body weights of up to 400kg (880lb), tackling heavier game with ease if head and neck shots are employed.
 
Of the core bonded bullet designs for use on tough game, Woodleigh (Protected Point) and Swift (A-Frame) produce stellar performers. These two brands should always be the first consideration when hunting tough game, both offering 200 grain bullets, capable of withstanding magnum velocities with ease. These projectiles work extremely well at high impact velocities and the .300 Weatherby has no trouble keeping velocities well above 2400fps out to 300 yards or so. Swift also produce the highly traumatic Scirocco projectiles which are emphatic killers when bullet weights are matched to game weights accordingly.
 
Barnes bullets, as mentioned in the factory ammunition section, have great strengths and Weatherby have a great load in the 130 grain offering. The only negative aspect, is that the combination of the 1:10 twist rate, freebore and ultra velocities can prevent some rifles from being able to obtain optimum accuracy. Nevertheless, in rifles that produce desirable accuracy, the 130 grain TSX is a hard hitting, deep penetrating bullet, ideal for goat, deer and boar. As bullet weights are increased, penetration increases.
 
Barnes projectiles like to be put to work, the harder the Barnes TSX is made to work the better with 150 grain bullets working well on 150kg animals and 165-168 grain bullets on 200-320kg (440-700lb) animals. The 180 and 200 grain Barnes bullets are to some extent limited by the bore diameter, a somewhat difficult factor to explain, more easily recognized in the field. The heavy TSX bullets are capable of full cross body penetration on large, heavy game, but, regardless of muzzle velocities, wound channel diameters are not nearly as wide as is produced in the wider bores. The .358 225 grain TSX driven at mild velocities of 2500fps helps paint the full picture very clearly. But as a rule of thumb for the 180-200 grain Barnes 30 caliber TSX bullets, heavy body weights are the key, delivering fast killing on body weights of up to 400kg (880lb) at impact velocities of above 2400fps. As body weights approach 600kg (1300lb), regardless of exit wounding, delayed killing can be expected, limited by bore diameter, not bullet design. 
 
Berger’s 175-210 grain VLD projectiles are very useful in the Weatherby for long range hunting. These projectiles produce frangible wounding in the absence of high velocity (in the absence of disproportionate to caliber wounding) but do require that bullet weights be matched to game weights in order to initiate full fragmentation. The current 175, 185, 190 and 210 grain VLD designs work best on game weighing between 90 and 180kg (200-400lb) with the 210 grain VLD continuing to produce good performance on heavier body weights of up to 320kg (700lb). Full fragmentation can be expected at velocities as low as 1400fps. In instances where game encountered are much leaner than expected and where no bone is hit (liver shots), the cut off point for full fragmentation can be as high as 1800fps. Fortunately, the .300 Weatherby does its best to help, launching the VLD bullets at extremely high velocities, aiding retained velocity down range.

Nearly 60 years on, the .300 Weatherby is finally coming into its own, thanks largely to bullet designs and optics, capable of utilizing the impressive velocities produced by this cartridge. Along with this, Weatherby now offer true long range rifles featuring full contour barrels and suitable stock designs.
 
This cartridge is a highly emphatic and often spectacular killer of medium game, tackling a wide range of body weights under a variety of conditions. Realistic expectations are the key to great success when using the Weatherby. Optimum performance can only be achieved through accuracy and unlike a more mild .30, such as the .308 Winchester, the Weatherby and its .300 magnum kin call for a greater level of attention and awareness towards both rifle accuracy and shooter technique. A poor shot with the .300 Weatherby is far less effective than a single and perhaps rather easily well placed shot with a .308. But when it all comes together, an accurate rifle chambered in .300 Weatherby Magnum, suitable projectiles and optimum technique, well that’s something.

After reading this article, I fully intend to work on solid loads in other bullet weights as well. Having the added variances for hunting different sized animals sounds like a great way to go. This is especially so since this article explains and matches bullet channel information with different bullet weights compared to different sized animals. 

I liked this article and will definitely be looking over this site for other interesting articles on other calibres.

5 Rifles You Should Shoot Before You Die

by Woodsbum

Here is another interesting article that I felt inclined to include. This one I actually agree with. The fact that I own 4 of the 5 only holds a HUGE amount of weight to how I see this article…. Just saying.

Here is the article that I am speaking of:

*****************************************************************************

5 Rifles You Should Shoot Before You Die

By M. Christopher published on in Firearms

I want to let all you in on a little secret. Some guns are just too impactful on a shooter to let you go through life without shooting them. Many of you may already have spent some time behind some of these rifles, but I have a feeling that some of you shooters haven’t shot all five. Let’s take a look at what I feel are five rifles that you should shoot at least once.

1. Ruger 10/22

The Best To Date. The Ruger10/22

The Best To Date. The Ruger10/22

The Ruger 10/22 has been a staple for many new and experienced shooters alike for over 50 years. Not only is it incredibly accurate and reliable, but it is infinitely customizable with thousands of options for aftermarket stocks, barrels, triggers and so on. With the price to get into one of these rifles at right around the $220-$240 mark, not having one in your collection is a disservice to yourself. Right out of the box, they provide a very pure shooting experience that will make even the best shooter better for pennies on the dollar.

2. Remington Model 700

Remington 700 SPS in .22-250

The Remington 700 is the first choice for precision shooters, hunters, police, and military since the early 1960s. A proven platform that lends itself well to whatever task you might have at hand while being almost as customizable as the 10/22. Working on your rifle shooting fundamentals with the strong and accurate bolt action will teach a shooter many things—along with how to handle a good bit of recoil. There are few things as much fun as lobbing big .30 caliber bullets hundreds of yards onto a tiny target. Going through life without experiencing the Remington 700 would be just wrong. Some of my most enjoyable range days have been spent behind one on the 500-yard bench.

3. Marlin Model 336 in .30-30

Marlin introduced the 336 in 1948. Since then, no rifle in America that has put more food on hunters’ tables.

Marlin introduced the 336 in 1948.  Since then,  no rifle in America that has put more food on hunters’ tables. I almost chose the Winchester 94, but felt the side ejecting 336 would be a better fit for the modern shooter because it allows you to mount a scope low to the receiver. It is hard not feeling like a cowboy when cycling the lever action. I have to admit, the 336 is quickly becoming a fast favorite of mine. I really enjoy the hard-hitting .30-30 cartridge when milling around in the hunting lease’s dense forest. The 336 rides with me in the truck just in case I run out to the lease on a whim. Getting into a good lever gun can be done for under the cost of a name brand handgun making it an affordable rifle to add to your collection.

4. AR-15 Chambered in 5.56

Customized AR-15 carbine

The thought of going through life without experiencing America’s most popular self-loading rifle gives me chills. It has become one of the most adaptable rifles on the market with a blue million calibers to choose from, barrel lengths, different stocks, and accessories coming out the wazoo. The AR-15 in its purest form is the rifle that you really should get behind. The 5.56 (or .223 Remington) is incredibly light recoiling while still packing a nice punch downrange. I personally introduce most new shooters to a self-loading rifle on a 20-inch AR-15 with standard A2 carry handle with iron sights. The beautiful thing about the AR-15 is that after you spend some time on the rifle, you can modify the rifle to your taste.

5. The AK-47 in the Classic 7.62×39

Century Arms C39v2 American AK

Who can say no to the classic AK-47 chambered in the powerful 7.62×39 cartridge? It isn’t me, that’s for darned sure. Right now is an exciting time for those of you that are after an AK-pattern rifle with so many great options on the market and big manufactures—Magpul et. al—getting behind the accessory market. The rugged reliability that has made the AK legendary is something that every shooter is sure to enjoy. Out of all the centerfire rifles on this list this one is the most economical to shoot steel-cased 7.62×39 ammo coming in at under a quarter per round. Couple the inexpensive nature of the ammo with the industrial feel that the rifle has in your hands and you have something really special that you should really treat yourself to.

There you have it. Now get out there and shoot these fine rifles, your trigger finger will thank you.

******************************************************************************

Again, I own 4 of the 5 models listed above. The only one I do not own is the AK-47 and that is because I opted for another AR in a slightly different configuration. The AK also does not fit me as well as the AR. It is definitely one of those rifles that deserves to be on this list, however.

For those that are looking to start out with rifles and have no idea what to get, I would suggest any shooter just go buy the 3 hunting rifles and then choose the AR or the AK. With those 4 rifles, assuming you get the 700 in one of the larger .30 caliber options, you can hunt every furred animal on the North American continent. By adding what is called a “battle rifle” by many, you then add self defense to the mix and have a well rounded arsenal with minimal expense.

No matter how you shake it, these rifles are really the gold stand for each of their respective classes. Go out and try your hand with each one and have some fun!

5 Beginner Hunting Rifle Rounds

by Woodsbum

One question I get a lot is about hunting calibres for beginners. I get this question so much that I have been tempted on numerous occasions to just make a list of my personal top 5 and distribute that at my hunters education classes. Lucky for me that some guys over at Guns.com have taken it upon themselves to make their own list.

Here is the article.

****************************************************************************

While hard, long and flat rounds like the .30-06 and .308 appear to dominate the North American hunting rifle scene (and even the popular .223 is making a name for itself as a surprisingly capable deer round) these cartridges are not really the best choice for someone who has never stalked whitetails before, let alone shot a gun. What should a fledgling deer hunter look for in a starter rifle? A caliber that has proven itself capable of getting the job done, a reputation for at least ‘minute of deer’ accuracy but also manageable recoil that won’t send a rookie running back to the cabin with a sore shoulder.

There are actually quite a few choices out there with such a proven history (.270 Winchester for instance), but here are my top five:

1.  .30-30 Winchester

Many hunters, including myself, started their hunting career with a .30-30 and all you need is a random sample of local hunters to realize that this over 100-year old round remains one of the best and most loved deer calibers in the woods. While not a long range affair (past 200 yards and you start getting into artist territory) it will bring down mobile venison and anything smaller at your standard distances.

.30-30 Win

The 170-grain bullet was designed for the brush and, boasting low recoil in small carbines like the Winchester 94 or Marlin 336, it is compact and well suited for a new shooter stalking denser forest. If the lever action isn’t your style, H&R chambers their Handi Rifle in .30-30 that can be used either open or with a scope mounted.

2.  .243 Winchester

The .243 Winchester came out in 1955 as a necked down .308.  It was an instant hit and remains so today, especially with folks conscious about meat preservation. With a 100 grain bullet pushing 2,900 fps the .243 quickly gained a reputation for being a lightweight deer round. A little light for black bear, it does well on whitetails and pronghorn antelope out to 200-300 yards and it does it without all heavier recoil that comes with larger rounds—in fact it’s pretty much a perfect compromise between zip and kick.

.243 Win

I know two women who hunt exclusively with the .243 and both have used them for years and shoot quite well with them. The fact that nearly every manufacturer in the business chambers either a bolt-action or a semi-auto rifle in .243 Winchester is a testament to this rounds popularity.

3.  .44 Magnum

When I was younger, a friend of mine was dating a woman who hunted with nothing other than a Ruger .44 Magnum semi auto rifle.  According to her, it was the only rifle she was ever comfortable with and she killed many deer with it. While certainly not a beginner’s handgun round, even in a rifle, the .44 Magnum is well suited to new shooters who have never had experience with a larger caliber but would like an introduction.

.44 mag

At close ranges of a 100 yards or less, a 200 or 240 grain bullet will take down any white tail deer or a black bear with little effort as long as the shooter does their part and puts the bullet through vitals. Recoil is low in rifles and there is very little muzzle blast, which is ideal for new shooters while the pistol caliber often means more rounds in the tube.  For someone looking to use a .44 Magnum rifle, Henry Arms, Marlin, Rossi, all make lever action rifles and H&R chambers their Handi Rifle in this hard hitter and comes ready for a scope to be mounted right on top.

4.  .257 Roberts

While not quite as popular as the .243 Winchester, the .257 Roberts has certainly earned its stripes over the years. Ned Roberts took the 7x 57mm case and necked it down to .25 caliber to make one of the best .25 caliber cartridges ever designed. Known to most simply as ‘the Bob’ the .257 Roberts is in the same league as the .270 and is better in my opinion than any of the 6mm rounds out there.

HSM .257 Roberts

The most common load encountered is the 117-grain bullet, which averages about 2,800 fps. While infamously loved by many but never as widely seen other calibers, Ruger and a few others chamber rifles in .257 Roberts.  You can also usually find a used Remington on the shelves just waiting to be snatched up, sometimes for bargain prices.

5.  .35 Remington

Another round from days gone by is the venerable .35 Remington. Originally chambered for the Remington Model 8 semi auto rifle in 1908 it has found its way into lever action rifles and is still one of the best close range deer cartridges for brush hunting.

35 Remington

You will most commonly encounter the .35 Remington in Marlin 336s and its 200 grain bullet moving at 2,000 fps gives it a clear edge over the .30-30 in performance. While more powerful than the .30-30, the recoil of the .35 Remington is still less than that of the .30-06 and 7mm Magnum rounds. In rifles like the Marlin 336 you still have a compact rifle and, chambered in .35 Remington, you will have a bruiser on deer but not bruises on your shoulder.

***************************************************************************

I actually grew up using the 30-30 and the 6mm Remington as my first calibres for hunting. They both worked great for me and were surprisingly easy on my shoulder as a new hunter. The 6mm is about the same as the .243 in case you didn’t know. The 6mm is faster and is actually close to the .244 Remington, but you get the idea.

Of these calibres listed I was surprised by, but ultimately agree with, the .44 mag as a rifle calibre. As years have gone by I have thought quite a bit about getting a lever action rifle in .44 mag for new hunters and deer hunting out of a tree stand. This configuration seems like it would fit perfectly between the bow hunting ranges and most rifle ranges: kind of that tree stand range mentioned earlier.

Although I have numerous firearms, I only have one rifle that could be a beginner calibre. This is something that I will have to evaluate myself since I am wanting to get my wife into hunting and high power shooting.

As for the rest of this article’s top 5, I would agree that they are great beginner rounds. The fact that the .270 wasn’t included does make me thing, however. Finding rifles that shoot the .257 Roberts is not really going to be an easy task. Maybe they included it because there might be a few of these hanging out in grandpa’s closet? I am also not that sure how many .35 Remingtons I have seen sitting on gun shelves in the last 20 years, but I could probably count them all on one hand.

It is not going to be too long before I have to start thinking about what rifle I want to get my wife to start shooting long range with. Having this list as a starting point will help me out, though. Hopefully, it will help you as well.

Handgun Self Defense Ammo Tests

by Woodsbum

Gunguy sent me a link that I felt compelled to included here. Of course there are thousands of articles on this subject, most of which contradict all the other articles out there. The interesting thing about this one is that it downplays ALL handgun cartridges and calibres as “sucking.” This was the first time I have seen someone take the stance on handguns in the use of self defense. It truly shocked me that there was no underlying .40 cal fanboy tone or a shadowed “.45 auto is the greatest round ever created.”

Now, please remember that I did not write this article. I have merely linked it and copied it here for ease of your reading. There are some additional charts on their webpage that show the results of various loads, bullets, etc. If you want that detail, please check out the article on Lucky Gunner.

Here is the article:

Project Summary

Over the last few months, I’ve been working with the rest of the Lucky Gunner team on another one of our epic experiments, which we’re proud to finally unveil: ballistics gelatin testing for over 100 self-defense handgun ammunition loads. 117 to be precise, and that’s just round one. This testing will be ongoing, and we’ll keep adding to the results as we have the chance to test more loads.

If you came here just to see the data from our tests, you can use the handy menu above to skip right to the results section. If this whole ballistics testing thing is new to you, or you want to know more about our process, then you might want to keep reading. If you’re more of a “bottom line” kind of person, you can skip over both the setup and the test results and check out the conclusions section. However you use this information, we hope you find it helpful when picking out your next self-defense load.

Ballistics Testing in Plain English

The science of wound ballistics can be a daunting topic, especially if you’re not inclined to use your leisure time to study physics and anatomy. At the end of the day, it’s really just the study of how and why bullets inflict damage. That sounds fairly straightforward, but even experts who study this for a living can’t seem to all agree when it comes to the effectiveness of handgun ammo.

The reason for this lack of consensus is simple: handguns suck. If someone wants to kill you, and the only way to prevent that from happening is to shoot them, a handgun is far from the ideal firearm to use — they just happen to be the type of firearm we’re most likely to have immediate access to. Contrary to what Hollywood has ingrained into our consciousness, shooting bad guys with pistols doesn’t make them fly backwards through the air, crashing into a bloody, motionless heap. In reality, the effects of wounds from handguns are unpredictable and often not very dramatic. So the study of handgun wound ballistics is not always clear cut, and any speculation we can make about how a given self-defense load will perform in the real world will be, at best, an educated guess.

ammo boxes clear ballistics
Just a few of the 117 handgun loads we tested for the first round of our project.

Bullets fired from handguns do only one thing: poke little holes in stuff. If the little hole doesn’t go through something that’s important for a human being’s body to remain upright and functioning, that person can still go about their business, which may include trying to hurt other people.

Of course, sometimes violent attackers give up or flee before shots are actually fired. When the mere sight of a gun in the hands of a would-be victim doesn’t do the trick, an assailant will often give up once fired upon, even if they haven’t sustained wounds that would cause their bodies to shut down right away. But these are examples of what Bob Ross would have called “happy little accidents”. It’s great if the bad guy gives up, but we can’t count on that happening. We have a gun to prepare for the worst, and in the worst kind of violent attacks, the bad guy doesn’t give up until he is physically incapable of doing you harm.

So with that in mind, a handgun can quickly and definitively stop a determined attacker only if two conditions are met:

  1. The gun must be fired at a so-called “vital area” of the attacker. This usually means the heart or the brain/spine. Hits to the lungs and other organs can also be effective, but results may be slower.
  2. The bullet must have the ability to penetrate whatever is between the muzzle and those vital organs in order to disrupt their function — for non-uniformed civilians, this typically includes clothing, tissue, and bone.

That’s it. No matter what else may happen during the course of a lethal confrontation, if you shoot the guy in the right spot with a bullet that penetrates deep enough, the threat will go down.

The first condition depends on the person operating the gun. No amount of bullet technology can make up for a miss. But as for the second condition — how do we know if the ammo we have in our self-defense gun is up to the task?

Conventional wisdom says to use ammunition with a hollow point bullet. These bullets are designed to expand upon impact with soft tissue. The expansion deforms the bullet and increases its diameter, which increases the likelihood of the bullet hitting something vital inside the target. Commercial hollow point technology is decades old, and there are dozens of different bullet designs on the market for all of the popular handgun calibers. So aside from the marketing materials put out by the ammo manufacturers, how are we supposed to know which bullets are the most effective?

hst-bullets
Left: Jacketed hollow point bullet pulled from an unfired Federal HST 147 grain 9mm cartridge. Right: An expanded 147 grain HST recovered from a block of ballistics gelatin.

That’s where ballistic gelatin testing comes in. Back in the late 1980s, the FBI began to use blocks of gelatin made from a solution of water and a powdered form of miscellaneous animal parts — called “ordnance gelatin” or “ballistics gel” —  as a substitute for living tissue for testing the effects of duty ammunition. Firing bullets into the gelatin gave them some idea of what the bullet could do inside a person — in particular, how deep the bullet could penetrate, and the degree to which the bullet might expand or deform.

Ordnance gelatin isn’t an exact simulation of living flesh. People and animals have skin, bones, tendons, and organs that are all different in terms of hardness and density. These variables can cause bullets to deflect, fragment, or otherwise behave in unpredictable ways. Conversely, ordnance gelatin is homogeneous, and free of internal obstructions, so the way a bullet behaves in gelatin is indicative of a real life best case scenario. Bullets will not always provide the same results on living tissue that we see in gelatin, but we can expect bullets that perform poorly in gelatin to have a lower success rate on humans, and bullets that perform well in gelatin are more likely to overcome some of the unpredictable variables encountered in the real world.

The other advantage of using a consistent medium like gelatin is that it allows for an “apples to apples” comparison between ammo loads. Each block of gelatin has the same physical properties, so bullet A fired into block A can be compared to bullet B fired into block B. This provides a much more scientific and objective method for comparing ammunition loads than anecdotal reports from real life shootings where there are a plethora of unknown variables to consider.

see-through-block

Today, this type of testing is made even easier with the advent of synthetic ballistic materials. The “real” organic ballistics gelatin blocks used by the FBI today are still made from dehydrated animal tissue. They provide accurate results, but they’re time consuming to make and they have to be refrigerated until almost immediately before they are used. And after all of that, the fired bullets are difficult to see through the cloudy, mud-colored organic gelatin.

Synthetic gelatin from the company Clear Ballistics is temperature stable up to 240° F, so the blocks can be shipped directly to the end user without melting or deforming. These blocks are also completely transparent, so the test results can be observed without cutting into the block. Test results using Clear Ballistics blocks come very close to results using organic gelatin, at least for comparing the penetration and expansion properties of handgun bullets. In addition, the convenience of working with the synthetic gelatin allows testing on a scale that is not practical with a substance as delicate and labor-intensive as traditional organic ordnance gelatin.

Lucky Gunner Ballistic Testing Standards

The goal of our project is to test as many loads as possible in order to determine how they compare to the FBI standard recommended penetration depth of 12-18″. We also want to know how well the bullets expand when they encounter a barrier of heavy clothing before entering the gel. Whenever feasible, we tried to duplicate the testing protocol reportedly used by the FBI, but our first priority was to be consistent, using the same procedure and conditions for every load we tested.

ballistics gel

We fired five rounds of each self-defense load using short-barreled pistols positioned 10 feet from a Clear Ballistics synthetic gelatin block with a four-layer heavy clothing barrier placed in front of it. The first shot of every test was filmed with a high speed camera, and we took high resolution photos of the gelatin blocks after the first and fifth shots of each load. We measured penetration depth and later, we recovered the fired bullets from the gelatin blocks, measured their diameter, and took additional photos.

Here’s a little more on how and why we set up our test this way.

Distance

Each shot was fired with the muzzle approximately 10 feet from the surface of the gelatin block. The FBI used to test handgun ammo at 20 yards as well as 10 feet, but they found very little difference in the data at these two distances. The current practice of the FBI is to use the 10 foot test for handgun ammo, and that’s what we’ve followed here.

Heavy Clothing Barrier

To get an idea of how a bullet will perform under various real world conditions, the FBI tests each load with a variety of barriers placed in front of the gelatin. They start with a plain block of “bare” gelatin with no barrier, and follow up that test with a barrier of heavy clothing, and then hard barriers of steel (to simulate an auto body), plywood, wallboard, and auto glass.

heavy-clothing

Because non-law enforcement self-defense shootings are highly unlikely to involve firing through walls or cars, the bare gelatin and heavy clothing tests are most relevant for the average civilian gun owner. In order to test as many loads as possible, we opted to skip over the bare gelatin testing and conducted all of our testing only with a heavy clothing barrier. Most of us train to fire at the vital zone or “center mass” high in the chest area of the target, which is an area typically covered by clothing.

The heavy clothing test simulates a scenario in which the target is wearing four layers of clothing: two cotton shirts, fleece, and denim. The FBI uses this standard not because it’s common for people to actually wear that exact clothing, but because they are common clothing materials, and when combined they represent something close to a worst case scenario for a bullet.

Clothing can present a challenge for some hollow point loads because the opening in the bullet can become clogged with clothing material and fail to expand once it reaches living tissue. This failure to expand gives the bullet a lower probability of striking a vital area, and also leads to the potential for over-penetration. Expanding bullets lose velocity quickly and are more likely to stay inside the target, but a hollow point that fails to expand can maintain enough energy to exit the target and potentially harm bystanders.

We used the same type of fabric specified in the FBI heavy clothing test, which calls for the following:

  1. cotton t-shirt material (approximately 5.25 ounces per yard, 48 threads per inch)
  2. cotton shirt material (approximately 3.5 ounces per yard, 80 threads per inch)
  3. Malden Mills Polartec 200 fleece
  4. cotton denim (approximately 14.4 ounces per yard, 50 threads per inch)

The four layers of fabric were stacked together and placed against the front of the gelatin block, secured with clothes pins to a bar suspended above the test block.

Five-Shot Trials

five-shots

For every load tested, we fired five shots through the heavy clothing barrier into a fresh block of gelatin. This gave us multiple data points for each load, which turned out to be important since many loads did not exhibit the same performance from shot to shot. Clear Ballistics gelatin can be melted down and re-used, but we started with a factory-new block for every five-round test.

Gelatin Blocks

The Clear Ballistics blocks we used measure 6”x6”x16”. Since we knew many of the loads would penetrate deeper than 16”, we used two blocks placed end to end, giving us the ability to measure the depth of rounds that penetrated up to 32”. Any rounds that completely penetrated both blocks and continued into our backstop were simply marked as 32” in our data.

Using Clear Ballistics gel blocks allows us to observe the penetration depth and wound channel without cutting into the block.
Using Clear Ballistics gel blocks allows us to observe the penetration depth and wound channel without cutting into the block. Here, we can clearly see the jacket, blue polymer cap, and individual shot pellets from a Glaser Safety Slug. It looks impressive in photos, but does it penetrate deep enough to be effective?

Short Barreled Handguns

This is one area where we intentionally deviated from the typical FBI test. Ballistics testing is most often conducted with full size or “service size” handguns with barrel lengths of at least 4”. However, most armed citizens carry smaller guns with shorter barrels, which means the bullets they fire will fly at a lower velocity than what is advertised by the ammo manufacturer. Ballistics data gathered using full size barrels can be misleading if applied to these small concealable pistols. We ran our tests with popular concealable handguns with barrel lengths we think are more representative of what the average citizen is actually carrying. The test guns used were as follows:

  • .380 ACP: Glock 42, 3.25-inch barrel
  • 9mm: Smith & Wesson M&P9c, 3.5-inch barrel
  • .40 S&W: Glock 27, 3.42-inch barrel
  • .45 ACP: Kahr CW45, 3.64-inch barrel

Measurement Methods

Penetration depth was measured from the face of the gelatin block to the farthest point of the bullet’s resting place. In cases where the bullet fragmented into multiple pieces, the depth of the largest fragment was the measurement taken.

In the photos of the gelatin blocks, you can see lines that appear to be a continuation of the wound channel that extends beyond the resting place of the bullet anywhere from 1/8″ to over 2″. From watching our high speed video footage, it’s clear these lines are the result of bullet “bounce back”. Once the bullet travels as far as it can go, the somewhat elastic properties of the Clear Ballistcs gelatin cause the bullet to “snap” backward slightly before coming to a complete stop. This same phenomenon occurs also occurs in organic gelatin, though the result is more difficult to see. These lines are typically ignored when measuring the penetration depth, and the farthest point of the bullet itself is what most other tests use to measure from.

Extended Wound Channel
Some bullets “bounced” backward in the gelatin before coming to a complete stop, which leaves an impression of the wound channel extending beyond the bullet’s resting place.

 

After we recovered them from the gel blocks, the expanded bullets were measured with digital calipers. The deformed and expanded bullets are not perfectly round, so we measured them at their widest point. While this is the most practical way to measure bullet expansion, keep in mind that the numbers can be misleading. Bullets that deform inconsistently with a fragment of jacket protruding unevenly on one side could potentially measure the same at the widest point as a bullet that expands more uniformly, even though the latter may indicate a better potential for tissue damage. We recommend taking under consideration the measured diameter data and viewing the photos of the expanded bullets for consistency and uniformity.

High Speed Video

The first round fired for each load was recorded with a high speed camera at 10,000 frames per second. You can click on the name of the load in the chart to see this footage, as well as additional photos and more detailed data. Here’s an example from one of the 9mm Speer Gold Dot ammo tests.

How to Read the Results

So what can you do with this information? There are a lot of varying opinions on what to look for and what we can learn from ballistic gelatin testing, even among qualified experts. Our goal isn’t to tell you which loads to use or which ones are best. We have thrown in a few of our observations here and there, but we’re not out to make any definitive conclusions. Admittedly, none of us here on the Lucky Gunner team are experts in the science of wound ballistics — there is more that goes into professional ballistic gel analysis than measuring penetration and expansion.

However, this also wasn’t a haphazard back yard experiment we tackled on a bored Sunday afternoon. We went to great lengths to set up consistent testing conditions and follow the same procedure for every trial so we would achieve results that could be reliably compared to one another. We’re providing this information as a service to the shooting community because there are so few resources available to help consumers distinguish one hollow point load from the next other than the brand name and color of the shiny foil-embossed ammo box.

The data from our ballistic tests is presented below in four separate charts, divided by caliber. We’ve simplified and consolidated a lot of the data in order to highlight the most important information and to facilitate easy comparisons between loads. High speed video footage, detailed data, and additional photos can be found by clicking on the product name for each load.

Penetration Depth

The charts below show the average penetration depth of each five shot trial, and the graph displays a representation of each individual shot. Clicking on the graph (or the photo icon if you’re using a mobile screen that’s too narrow to display the graph) will display actual photographs of the gelatin block we fired.

Click on the penetration graph of each load to see photos from the gel test like the ones above. The top image shows the first shot fired and the bottom image shows all five. Green circles indicate the location of each bullet. Bullets that penetrated greater than 32" are "off camera" and indicated with a green arrow.

Green circles indicate the location of each bullet. Bullets that penetrated greater than 32″ are “off camera” and indicated with a green arrow.

We aren’t ranking any of these test results ourselves, but if you’re looking for some standard to compare these findings to, you can start with the FBI protocol. Their standard requires duty ammo to penetrate between 12 inches and 18 inches in ballistic gelatin. We’ve highlighted this range in the penetration graph on our chart so you can easily see which loads came close to this standard, but that shouldn’t be read as a pass/fail test. We can’t assume that a load with any bullets falling outside of the 12″-18″ range should automatically be regarded as a total failure. Consider penetration, expansion, and weight retention, as well as consistency of a load from one bullet to the next. Also consider that the heavy fabric barrier we used is just one type of test, and results could vary for rounds fired into bare gelatin or hard barriers.

There may be some disagreement on the specifics of what to look for in these kind of tests, but you will find few advocates of ammo that penetrates significantly less than 12 inches, or expanding ammo that consistently fails to expand as designed. Consistent slight over-penetration (greater than 18″) is generally considered acceptable if the alternative is under-penetration, or inconsistent performance.

Why 12 inches?

The 18 inch maximum penetration depth standard makes sense to most people — too much penetration and the bullet can go clean through the target (possibly changing direction slightly before exiting) and onward to harm an unintended target. On the other hand, the 12 inch minimum penetration standard can be more confusing. If the bullet needs to reach the middle of the chest cavity where the organs are, wouldn’t we need a penetration depth less than half of that in most cases? Some of the reason for the 12 inch minimum standard is simply “playing it safe” and allowing for the possibility of attackers possessing greater than average girth. But part of the rationale is based on the simple reality of three-dimensional anatomy.

We typically imagine a potential attacker will be directly in front of us, facing our direction with squared shoulders, much like the paper and cardboard targets we usually use. But it should come as no surprise that this is not how gunfights usually go down. We have to account for a human target that may be turned slightly toward or away form us at an angle, or possibly even above or below us, or with arms partially obscuring the torso.

If you’re having a hard time picturing why this would affect the penetration depth necessary to reliably stop an attack, imagine you’ve just been ambushed by a 275 pound dude wielding a baseball bat. As he is rushing toward you, winding up the bat for a knockout blow, you manage to draw your pistol and fire a perfectly aimed shot at his upper chest. But since he’s in mid-swing, the bullet doesn’t go straight into his chest — it enters his arm just above the elbow and now has to pass through half an arm, a shoulder, a rib cage, and a lung in order to reach the heart or spine. A bullet that can penetrate only 9 inches might lodge in the guy’s rib; unpleasant for him, but not the definitive fight-stopping shot we want.

That’s a somewhat extreme example to illustrate the point, but it’s not an unrealistic scenario. These real life encounters are messy, and what constitutes “adequate” penetration in any given situation is not a universal constant. When ballistics experts have suggested changes to the 12 inch standard, it has only been in the direction of increasing that number, but for the time being, the FBI still deems the 12-18 inch penetration range to be ideal.

Expansion

For bullet expansion values, the chart shows you the average diameter of the five bullets fired and a photograph of the bullets retrieved from the gel block alongside an unfired bullet pulled from a cartridge in the same box of ammo.

Expanded Bullets
Click on the thumbnail of the expanded bullets in the chart to see an enlarged version. When the heavy clothing barrier clogged the hollow point, we left the cloth particles in place for the photos.

Unlike penetration, there is no widely accepted minimum standard for expansion. One commonly used threshold is an expanded diameter at least 1.5 times the original diameter, but that’s far from universal. Most law enforcement agencies that have a minimum standard for duty ammo tend to prioritize penetration over expansion, and consistent expansion is often considered more important than a specific target minimum diameter.

Weight Retention

One final criteria to consider with self-defense handgun ammo is weight retention. This is essentially a way to measure the bullet’s ability to stay in one piece while travelling through barriers and tissue. This is not as much an issue with modern handgun ammunition as it was with older bullet designs, but a few of our test loads did show a tendency to fall apart in the gelatin. This occurred for one of two reasons: separation of the jacket and bullet core, or a bullet that is intentionally designed to fragment on impact. Fragmenting bullet designs are common in high velocity rifle loads, but not nearly as popular in handgun ammo, though more companies have recently begun to produce them. In our tests, these loads did fragment as designed, but there is some question as to whether the principles that make fragmenting rifle bullets effective can be applied to slower-moving handgun bullets.

Some ammo is designed to fragment on impact. We measured the weight of the largest fragment to determine the percentage weight retention.
Some ammo is designed to fragment on impact. In these cases, we measured the weight of the largest fragment to determine the percentage weight retention.

Because the vast majority of the tested loads exhibited 98% or better weight retention, we haven’t shown that data in our chart (although you can find that info on the individual product pages by clicking on the name of each load in the chart). Instead, we’ve used an asterisk on the chart to indicate the few loads that retained less than 85% of their original weight on average. Looking at the accompanying photos will clearly show whether the weight retention failure was due to fragmentation or core-jacket separation. The core-jacket separation issue tends to be more common when bullets encounter hard barriers such as windshield glass or car doors, and a bullet’s weight retention in our heavy clothing tests can’t be taken as an indicator of how the bullet would perform against other barriers.

Permanent vs. Temporary Wound Cavity

One final aspect of ballistics testing we haven’t yet addressed is the wound cavity — the flesh that is disrupted by the bullet. The permanent wound cavity is the “tunnel” made by the bullet that’s visible in all of the gelatin photos. Bullets that expand or tumble will leave a bigger wound cavity than bullets that fail to expand.

The temporary wound cavity can be seen in the high speed video footage when the gel balloons and stretches as the bullet enters. As cool as that looks, it can be misleading. The Clear Ballistics synthetic gel has more elastic properties than organic gelatin, so the temporary wounding effects tend to appear more dramatic and aren’t a very good representation of the effects on living tissue. Furthermore, most ballistics researchers believe the temporary cavity created by handgun ammo does not lead to any significant wounding effects. Rifle bullets travel at a much higher velocity and can create temporary wound cavities that tear and disrupt tissue not even touched by the bullet itself (sometimes called “hydrostatic shock”). Because handgun bullets typically travel at relatively low velocity, they possess little to no capacity to induce this phenomenon.

Generally, for handgun ammunition, only the permanent wound cavity should be considered to have any reliable effect on the target.

Ballistic Test Results

.380 ACP Ballistic Gelatin Tests

As expected, .380 ACP turned in the weakest overall performance of the four calibers we tested, but a few loads fared surprisingly well. Most loads showed either good penetration but no expansion, or decent expansion with sub-par penetration. Only a couple of loads managed to show decent numbers for both. There’s a reason that .380 ACP is often considered “underpowered”, but careful ammo selection can help to mitigate its deficiencies to some degree.

9mm Ballistic Gelatin Tests

There were several 9mm loads showing adequate penetration with a decent amount of expansion as well. Some of the loads became partially clogged with the heavy fabric which prevented complete expansion and led to slight over-penetration in the 18-22 inch range. Only a few loads completely failed to expand on all five shots, and the fragmenting bullets were among the few to fall shy of the FBI’s 12-inch penetration depth minimum.

.40 S&W Ballistic Gelatin Tests

Under-penetration was very uncommon for the .40 S&W loads. On the other hand, some of the bullets had trouble with the heavy clothing barrier, leading to expansion failure and penetration that exceeded the 32″ maximum depth of our dual gel-block setup. Many of the loads that did stay within the FBI 12-18″ range showed excellent expansion, sometimes nearly twice the original bullet diameter.

.45 ACP Ballistic Gelatin Tests

As with .40 S&W, some of the .45 ACP loads became clogged up in the heavy clothing and showed severe over-penetration, but the loads that expanded successfully did so with impressive results.

Conclusions

Looking at all of this data, it’s tempting to try to sift through the numbers and determine once and for all which load is The One Bullet To Rule Them All. If that kind of data analysis gets you excited, then go for it. If, on the other hand, you just want to find a decent load for your carry gun, you probably don’t need to go through all of that trouble. To the contrary, we did all of this work on these tests so you don’t have to obsess over the ballistic performance aspect of your carry ammo.

If the self-defense load you use is listed here, and you’re not confident in the results you’re seeing, just pick another one that performed at a level you’re more comfortable with. But keep in mind, even though the gelatin tests can tell us a lot, there’s plenty of things they don’t tell us. Ballistics testing doesn’t tell us anything about the felt recoil of a load. We also haven’t addressed accuracy or muzzle flash (which can be an issue in low light). And maybe most important of all, no gelatin test can tell you if a given load will run reliably in your own self-defense pistol. This is all stuff you’ll have to test on your own at the range with your gun.

Once you find a load that works, whatever you decide, try to keep all of this in perspective. Choice of caliber and bullet are not the most important aspects of successful self-defense. Awareness, proper mindset, marksmanship, and discernment of when to use your firearm are generally far more critical to your survival than choice of gear. Having said that, knowing your carry ammo works not only provides peace of mind, there’s a chance that choosing a solid defensive load could be the one factor that tips the scales in your favor in a fight for your life.

******************************************************************************

As you can see from the article, not only did they do a large amount of testing, but they also have difficultly with spell check and grammar……

SERIOUSLY THOUGH:

I find it interesting that the testing is all done with certain “known variables” used as a basis of lethality. Such “known variables” are the 12″ (or 16″ in this article’s case) regarding ability to reach vital organs. I understand that there has to be some sort of baseline, but the whole idea that your bullet has to penetrate a certain distance to supposedly be more lethal only makes sense in certain instances. Let’s use the 3 main ways weapon systems take down an animal while hunting: exsanguination (bleeding out), hydrostatic shock, and penetration (big bore calibres). The fact that I used hunting as a baseline is because it is a tangible, viable and understandable way to show examples of how these 3 ways projectiles harvest animals.

Exsanguination takes place when you use a cutting type instrument like an arrow. If you have never bow hunted or seen an animal hit with an arrow, I suggest you examine this before you EVER consider getting into a discussion about stopping power or bullet effectiveness. The fact that my 4 blade Muzzy broadheads will put a hole bigger than my thumb all the way through a deer when shot at 30 yards is just amazing. The deer travel about 20-30 yards and expire. I know that any solid shot will allow me to find my animal less than 40 yards distance from site of impact. This is very common with properly placed shots with a bow and a broadhead designed to leave large wound channel. The results may be different depending on the broadheads used, but there is a common theme where the animal expires within a short distance due to the large, bleeding wound channel.

Hydrostatic shock is where the energy from the bullet is transferred to surrounding tissue and damage occurs due to this “shock.” If you have ever field dressed an animal and found that jelly like tissue throughout the wound channel, you know first hand what damage hydrostatic shock does. It makes the tissue no longer “viable” and thus causes the animal to expire due to that damage. A great example of this would be the deer my father harvested this last weekend. Although he missed the deer’s heart, one ventricle was ruptured and the other one was damaged enough from hydrostatic shock to have completely turned into jelly of sorts. Both lungs where also a mush and unusable. His animal ran about 50 yards and expired. Those that hunt with high power firearms understand and have seen that damage.

Big bore bullets literally poke a hole all the way through an animal. Expiration can be due to damage to internal organs, thus causing exsanguination or even complications such as pneumothorax where air enters the chest cavity and the lungs/heart no longer function properly. There is a degree of hydrostatic shock from the bullet pushing its way through the animal. The best way to imagine this type damage, however, is to image a sledge hammer being shoved through an animal. The sledge hammer isn’t going to be going as fast as many rifle calibres, but the damage is going to be remarkable.

What a lot of these tests don’t measure is the combination of damage that can be done. For example, the use of a hollow point bullet can cause a lot of hydrostatic shock. It can also do a lot of damage that can cause exsanguination if the round was fired into certain vital areas of the body. At the same time, a large calibre bullet being fired into tissue can also act like a big bore firearm at times. Organs can be literally punctured with a large hole that can cause this type of penetration damage.

The conclusion of this article is actually quite good. It simply tells you to use what you like, what seems to work and be competent in your abilities above all. “Awareness, proper mindset, marksmanship, and discernment of when to use your firearm are generally far more critical to your survival than choice of gear.” (Baker, 2015)

So in closing I will just say this: You should use whatever you WILL carry or CAN shoot well rather than what someone else tells you is best. If your full sized Glock is sitting in your nightstand because you are tired of it pulling your britches down, you have already lost the battle and have no real dog in the fight. Keep that in mind when other people talk. Chances are that their “carry gun” is sitting in their truck and not on their belt.

Loads for 45-70

by Woodsbum

Finding reloading data on generic or lesser known bullets is not an easy feat. Most of the time you have to work up your own data. A few months ago I found some 405 gr cast bullets for my 45-70 and spent a lot of time looking for some reloading data so I can get them out and test them. Unfortunately, the data I found was never inclusive of any powder that was available so I have had to back up and “punt.”

In researching other bullet loads I found some data on the use of IMR 3031 that I thought I could use to establish a base and work up some loads from there. While working on this, my father did the same thing with the use of IMR 4198 using the same bullets. Since we had two different powder loads to evaluate, I talked him into getting out his old chronograph and we went out to the gravel pit to do some testing.

First off, his loads are using 40 gr of IMR 4198 and the same 405 gr cast bullets. Since I had not done any real testing yet, I went ahead and put together some ladder tests from 42 gr of IMR 3031 to a max of 49 gr in .5 gr increments. We chronographed each shot to look at the velocity and then checked for pressure signs. Again, all this work was based around finding a good load for the 405 gr cast bullets we picked up. Here is what we found.

My father’s load using 40 gr of IMR 4198 shot at 1702 fps.

My loads worked out as such:
42 gr IMR 3031      1271
42.5 gr IMR 3031   1406
43 gr IMR 3031      1434
43.5 gr IMR 3031   1461
44 gr IMR 3031      1482
44.5 gr IMR 3031   1508
45 gr IMR 3031      1549
45.5 gr IMR 3031   1582 and the primer just began to flatten just a touch
46 gr IMR 3031      1586 and the primer flattened even more
46.5 gr IMR 3031   1589 and the primer flattened as far as I felt was truly safe for brass/rifle

The best range load for this powder, bullet and rifle seems to be around the 45 gr of IMR 3031 mark. Even though I now had loads for 45-70 using these 405 gr cast bullets, I wondered what Hornady 325 gr Leverevolution ammunition would chronograph. It was travelling at 1825 fps. Again, this is 80 gr lighter bullet than the ones we were testing.

Since we were out there I also chronographed my father’s 300 gr hollow point loads. He was using 46.5 gr of IMR 4198 in these cartridges and they came out at 1875 fps.

Lastly, there were some plinking loads that a friend of mine made. He somehow found some 150 gr cast bullets and loaded them up with 11 gr of Trail Boss powder. These seemed to be a very light and fun round to shoot. They were like oversized .22 lr with regard to recoil and sound. Again, we decided that these would be a great small game round and were an absolute blast to play around with. The speeds of these ranged between 1262 and 1283 fps.

My father also brought out his 45-70 Sharpes 34″ barrel rifle to play with. I have excluded the data from that since it really made my little Marlin 1895 GBL look anaemic with regard to the speeds these loads produced.

All said and done it was a great outing. We had a great time and I found that I need to procure myself some IMR 4198 for these heavier grain bullets.
