You have a very good point Bob, that some people really don't realize. Animals, and people, can take awhile to go down even after they are solidly hit. Skunks had been eating baby kittens here awhile back, and I saw one in the front yard earlier this spring. He ran about 25 yards after a solid chest hit with a .22. You know on that small an animal the .22 did some major damage...there was some rib bone sticking out the off side and the hit was in the heart/lung area...closer to the heart. I do believe I'd rather stick the barrel of a .44 down the throat of an attacking bear than my fist though.
Yup that is true, a .44 would be better. I do think carrying a revolver in case of a black bear attack is being just a little over cautious considering most encounters do not end in an attack. Not that it hasn't happened but again there is a slim chance.
I also don't think too many people can manage a number of repeated well aimed shots from a heavy caliber handgun at a charging black bear's head. They are amazingly fast sprinters when they want to be.
I'm just saying it may give a person a false sense of security.
