Shot my deer last year with my Cowboy Action Rifle. Marlin 94 in 357 magnum. Used the federal fusion ammo with GREAT results. If I didn't already have the gun on hand and the state I was in changed the reg's. I might buy a T/C Encore 20" barrel in 460 S&W. Then you can shoot 454 casuls or 45 long colts as well. Second choice would probably be a 44mag lever action Marlin.
