I shoot 110gn Vmax from my .308. I have never had a discernible exit wound on a coyote with them. About a month ago, I put a deer carcass out on a stack of pallets. Next morning there were a few magpies on it. From my dining room window, 70yds. Blew that magpie into a 25' circle on the ground. The surrounded pallets looked like I had hit them with buckshot and only one piece was big enough to tear the hardwood up. As far as I am concerned, these work better than the varmint grenades I used both in accuracy and in effect. I have never used Blitzkings so I can't comment on them.
