Here is a great video that shows how to field dress an elk in less than 10 minutes via the “gutless field dressing” method.
If you are wanting to save the hide to tan out, then this would NOT be the method to use unless you wanted a lot of small chunks of leather to work. I personally fight with the animal so that I can tan out each and every hide I collect. The leather is then used for various projects I have throughout the year.
For those that are deep in the woods and just need to get the meat out, I think I would definitely recommend this method.
Good luck and happy hunting this upcoming season!
