7mm Rem Mag is a great, flat shooting round. I have one and I love it, but for deer I find myself carrying my 243 more often now, just because it is lighter and shorter, and all around easier to carry. But for a treestand there probably won't be much spot an stalk, etc. The thing I don't like about my 7mm is the barrel length is 26" other than that it is a great shooter and anchors deer very well
