RE: You've talked me into it, i'm going bear hunting
depending on your set-up and the amount of KE your arrow is producing you could use expandables. That being said I don't like them for anything and don't use them. The biggest thing is a bears vitals are relitivly small compared to there body size so an accurate shot is crutial. broadside or quartering away only. if you can get it to the boiler room black bears are not that hard to bring down. You'll love it.
