257 Weatherby: I've never seen any other caliber come close to anchoring deer, RIGHT THERE.
300 Weatherby: Arguably, the greatest all around caliber out there. I've taken lots of game with it, including about 17 species of African game.
340 Weatherby: Very badass. 338 Winchester on steroids. IF when I ever go fro brown bear, this will be my caliber of choice.
