Black Bears are not that hard to kill, just know their anatomy (a little different than a deer's), and either have a broadside leg forward shot or a quartering away shot. The bigger the hole the better, not for killing purposes, but for tracking. Bear hair will act like a sponge so the bigger hole will allow more blood to leak out and get on the ground, if you don't see them drop within sight. If a 50# Longbow can do it, 50 or 54 cal roundball will.
Just like deer shot with a roundball they will die of Lead Poisoning. :rotf: DANNY
