What’s the best caliber for wolf?
223. The idea would be to kill a deer and leave it somewhere where wolves would find it, set up to shoot, and then leave the dead wolves in a heap on the lawn of the govt agency responsible for the ****....
I’m not much of a hunter, but given given the speed of a wolf the the distance I think a .223 would work. When I was a kid my uncle, a WWII vet, could shoot the a$$ off a fly with out of those.
