Hang on guys, I thought we were talking about back-up weapons aside from rifles.
My Primary would be either 458 lott or my 338 lapua depending on the terrain, distance, etc.
I would want one of the guys with me to have a 10 or 12ga pump. I would have a 500 S&W as a side arm.
Varmint Hunter, I believe he was talking about grizz. I live and hunt in black bear country and during bow season I've been on the ground and had them within 20 yards of me. I had one last year come out to my left and start walking right towards me. I just swayed a little to let him see and he turned and fled.
The thing with black bears, similar to grizz, is that you don't want to walk thru the thick stuff and startle them.
