I have shot 10s of thousands of rounds of 223 granted most was full auto lol. Will it work on tiny 10? I have no doubt. Would I shoot FMJ mil spec at them, absolutely not. I have had numerous ground hogs make it to the hole leaving a blood trail with a 55g or 62g green tip punching a nice little hole through them. Fox, coyotes cull deer all the same. 22cal hole punches through and the critter runs off. Yes little hide damage but you better do head shots or be good at tracking. I think a partition ,tsx or something that expands with out exploding would be much better.
