Agree, a few black bear in the general area as well. I usually carry a 357 though an incident like this, three attacking simultaneously, I magazine capacity could be an issue. My guess he wasn't carrying this with four legged wolves on his mind.
I dunno about that. He only needed one round. I bet the very loud report of a .357 would scare most of a "pack" away. And if 6 rounds of .357 can't do the job against any given bear then you were probably dead from the word go regardless of what you were carrying.
