I would agree that you prob won't have an issue with a bear. That said, for protection/defense....buckshot is a MUCH better option, imo. You aren't hunting...if there ever was a time you actually needed to use it, you likely won't have much time to aim. Plus, at close range buckshot is devastating...and would likely put down whatever it is you are shooting at. If not down, certainly slowed down big time or completely deterred. Panicking in the heat of the moment and missing with a slug...well that don't help much. My .02
