I've never been on a guided hunt, but wouldn't the guide have a large magnum backup gun? Would a guide back down on his minimum caliber restrictions if you held your ground and brought the 300 RUM, or would he cancel the hunt? Just thinkin' outloud because I don't pretend to know the answers.
I do know if I was a guide taking hunters with varying skill levels, I'd damn sure have something to stop that bear. But I don't even go to the 7-11 without packin".
