You are not going to get more than 6 rounds off at a charging black bear moving at 35 miles an hour (50 yards in 3 seconds) at a distance you COULD convince DNR it was a self defense shoot. Go with a 44 mag. Rounds left in the magazine after you get mauled or eaten are zero good.In GA woods give me my G20 with 15 +1 of Underwood hard cast 220 grains going 1200 fps. I would take that over a 6 shot revolver for anything in GA. I like the 10 extra rounds. If a grizzly was in the picture then I would be thinking of nothing less than a hot 44 mag in a handgun. If I lived way up north, I think I would have me an AR10 by my side with at least 20 rounds.
