The bison should yield approximately 700 pounds of meat and a unique trophy. I did manage to go varmint hunting one afternoon with my brother. We were using 6MM that he had hand loaded 55-grain bullets. The powder configuration he used was supposed to result in a muzzle velocity of 3,800 feet per second from a 24-inch barrel. The varmints we were shooting were gophers.
Gophers are grass eaters and therefore are less than appreciated by ranchers.
They also create holes in the ground that if cattle or horses happen to step in, the result more often than not will be a broken leg requiring the cow or horse to be destroyed. Suffice it to say, the ranch foreman was glad to see us thinning out the gophers. Due to the prolific nature of this type of varmint, the .22 long rifle is very popular because of inexpensive cost of ammunition. Magpies and other scavenger birds quickly picked up the expended gophers. It was delightful.
