If I had to choose I would take my Remington 700 in 8mm Mag. It's very versatile I can shoot 150gr bullet at 3400fps or a 220gr at 2900fps that should cover just about anything you would ever need a rifle to do on any continent.
What about small game, survival and or self defense. I'd hate to try eat a Rabbit pounded with that cannon!!!


(or cook it for that matter)
