Hunted deer, elk and antelope in Wyoming for over 50 years. I started using a .308 in the late 60's and decided the recoil was better than a 30/06, so I stuck with it. Never considered anything else since. My guns seem to like bullets in the 165 gr. range and most things I've shot don't go far. Either gun you mentioned is more than capable. If the 7mm bothers you, leave it home, it ain't worth it to worry about recoil on a nice hunt in MT. Besides, hunting means getting as close as you can, for the best shot and a clean kill. Use the .308.
