I'm sure this is a stupid question, but I know next to nothing of rifles and shotguns and what would be best for defense against larger animals in the woods. I know handguns are pretty much useless for anything larger than a Coyote. I go bow hunting and have come into woods fresh with bear and cat dung in the past. Where I'm from I don't have much for Brown bear, just black, and am curious as to what would be best to have around incase I come upon one of these beasts. I have access to a 30-30 lever and a Remington 870 15". I figured a slug in the 12ga would be best at anything 50yrds and closer, but like I said, what I figure isn't exactly based on experience or knowledge. Would appreciate any insight or helpful hints. Currently I carry a 45acp as its the biggest I can carry easily, but am completely prepared for slinging on a rifle or shotgun.
