If it means anything I've hunted in Maine, PA, SC, and a half dozen western states using a .270 Win. and never felt under gunned. That rifle shoots under 1 MOA consistently with Nosler 130 BTs and 54 gr of IMR 4350 powder. I would have to sit and count how many deer (whitetail and mule) and a few antelope I shot with that rifle and practically all of them dropped where they stood or only traveled a short distance at ranges from literally 10' off the end of the barrel to over 400 yards. Unless you're going after big bears there is no reason the 270 Win won't fill your bill. But frankly either rifle will work. I also like the 7-08 because it comes in shorter lighter rifles like my Browning Micro Hunter.

I would go with the 7mm-08 myself, but I'm biased. I already have 3 - 243's.

I prefer the 7mm08
