I agree that it doesn't matter if it's overkill (if there is such a thing), all that matters is that the animal dies quickly and then you have fun!!! Hunting with small cals is fun, hunting with big cals IMO is even more fun because you can watch the animal go splat. Ok I admit it is a bit sick, but watching an animal that was taken with a cal too small die in agony is worse that a quick grusome death. Also some people just enjoy having their shoulder hurt by recoil

, hahaha.
