One of my carry guns is a 3 inch M60 stainless. I only carry it on hikes into the back country, etc. I load 110 Barnes HP's at about 1000-1100 fps. for it. They are designed to open from a 2 inch at 900 fps.
I've run into six bear while doing this. All of them ran at the sight of me, including a sow with a cub. Another was at 15 ft. Not much of a threat.
Mackay's daughter works where there are much more serious bear threats. Kalifornia bears are all black bears.
Been carrying guns in rough places all of my life. Never needed one to deal with an animal. People are a different matter. E
