Depends on what you are hunting with it. If you are primarily hunting elk I would probably use a .300. If not the 7mm is a peach to shoot well. I hunted moose for many years with a .338 win mag and dropped down to a 7mm rem mag 3 years ago and will likely never need more gun now that I have used the big 7. In 3 years it has killed 2 bull caribou, 2 pronghorn antelope and 1 bull moose. All with 1 shot kills with shots from 413 yds (antelope ) to 125 yds ( moose ). Boom, on thier nose ! I love my 7 mag.
