The Wolf Ammo will shoot about 15 out of 20 times in my 7.62x39 barrel, but reloads work every time. The Wolf will sometimes fire on the 2nd or 3rd hit but a few will never fire. I have been shooting 6 grains of Trailboss with a .309 lead 165 grain bullet. Personal experience tells me this a good load for squirrel, armadillo, and coyote. I am going to load some hotter 125 grain bullets for the late doe season. My sons and I are going to try and kill a deer with all my barrels this year.
