I agree with the above posts. But as driftrider said, don't "out-gun" yourself. All you'll end up with, is a sore shoulder at the range and more meat damage in the field. I went from a 300 winmag to a 308 and my "groups" shrank dramatically. As long as the shot is where it should be, dead is dead, no matter what caliber you're shooting. Being a succesful hunter is all about "shot-placement".
