I went moose hunting in Newfoundland this past October. The guides were telling us how they use 270's and 30.06's. That's what most of the locals use up there. They feel there is no need to use a magnum rifle. I used a '06 myself. The 270 will do just fine unless you are going after the big Alaskan/Yukon variety or are going in grizzly country. Then I'd reccomend something bigger.
