For several years I have been trying to dial in my .300 Wby to get the best accuracy and consistency out of it. For some reason the actual factory loads seem to shoot best, but they are REALLY expensive. To reduce cost and be able to recreate these loads I started do some searching on the factory load data to be able to load my own. There seemed to be absolutely nowhere to find this data online. Of course that was until I ran across someone on a forum that had scanned pages from some older book was given. It actually had all the Weatherby factory load data on 5 pages. All Weatherby calibers seem to be included from the .224 through the .460.
To make it easier for everyone here are those pages so you can also reload to factory ammunition specifications.
Normally I use either Winchester or CCI primers. I am not sure how much difference this will make overall, but it might necessitate the use of a chronograph to see if the muzzle velocity is any different between factory and what I reload. Oddly enough, I actually find it difficult to find Federal primers in the places I shop. This makes me wonder if it is a regional thing, but I have not really researched the topic of primes to ANY degree. I do like to shoot the 209 primers out of my starter gun though. It makes big bangs and startles people on the firing line……
After having found this data, I might take it upon me to search out the factory data on other brands such as Hornady Leverevolution line. Since they sell their own powder, I would think that data would be available somewhere. Many other companies just use bulk powder rather than canister powder that is sold to the general public. Either way, this data above is VERY nice to have and any other information I get will definitely be passed along as well.
The link I provided actually goes to the NIJ website’s training site. They provide all sorts of online resources and training for various different programs. Although I am not a LEO and don’t really care about a lot of the content on there, the training programs for firearms are actually quite useful to those reloading and wanting to learn more about firearms.
As always, be safe and have fun!!!!
