You will probaly be fine with that load, if you rshot placement is in the vitals. You may want ot consider the Nosler Accubond or Winchester Fail-Safe, or perhaps the Barnes X-Bullet if you want more penetration for the off chance that you need more penetration. Remember, piles of black bears have been tken with the old 30-30. In fact, my uncle took one (from a defensive standpoint) with a 1911 shooting hardball. I guess that, like anything else, shot placement is key. I like premium bullets for black bears, though, for what it's worth. Good luck
