I have talked to a lot of guys and done a lot of research 45-70 lever actions have been known to take bigger game. I prefer a 45-70 with a decent scope. The rounds you can get for that are very interesting if you wanna spend the money you can elephant rounds for it or bear defense rounds.
Yea I know that would be a bummer. When I was talking to a lot of guys that hunt up there they told me that if I take a pistol that I better shave off the front sight post so it hurts less when the bear takes it away and shoves it up your ass
