I was just wondering where all you guys stand on this topic. I' m looking to get a gun for elk, moose, and some day maybe even brown bear. Do you think I would be better off with something fast like a 300 Ultra Mag. or would I do better with a larger caliber like a .338 Win Mag? I know both of these rounds will do a good job, but if you had to pick between speed or mass, which would you choose? I don' t have very much experience with the larger calibers, so I don' t know how effective a larger frontal area is on big game. I would really appreciate any comments on the subject. Thanks!
