>>896106For bears you want a 12 gauge with rifled slugs, or a .454 Casull handgun, like a Ruger Alaskan. Here's a cool story...
> Brush stopped when he heard a twig snap behind him. Turning his head toward the sound, Brush saw a monstrous brown bear charging toward him. "There was no warning," he stresses. "None of the classic teeth-popping or woofing, raising up on hind legs, or bluff-charging that you read about. When I spotted him he was within 15 yards, his head down and his ears pinned back. He was coming like a freight train…in total chase-mode."http://www.fieldandstream.com/photos/gallery/survival/animal-attacks/2009/08/charging-grizzly-killed-alaska#page-3This guy lucked out. Good shot placement under stress is a huge survival factor.
