Any advice on a bear gun?
I'm thinking Browning BAR .338 Win Mag. Anything better to get of a few shots before being mauled?
Ruger now makes a short-barrelled revolver in .454 Casull or .480 Ruger called the "Alaskan". I would imagine it would be a good defensive piece for use against bears.
personally, i'd go for a large bore double. .375 h&h or a .416 rigby ought to do it.
i say a double for the simple reason that the gun is simple and is it's own back up. there's 2 barrels, triggers and firing pins. anything goes wrong, you still got another. also, you can get off two shots quicker in a double than in anything else or you can fire both at the same time.
2d choice would be anything magnum in an enfield action.
