RE: Which 7mm bullet?
My Son and one of my hunting buddies both shoot 7mmRemMags. They both shoot one bullet (which happens to be one that shoots very accurately out of their rifles - and should be the first consideration when selecting a bullet IMO). They hunt/kill deer, elk, moose, and caribou, and black bear. They both use the Win Supreme 160gr Fail-safes. This is not to say another bullet wouldn't be as good, but my point is this particular bullet does an excellent job for these two men. There are many "good" bullets out there for the man who uses factory ammo. Just find the one that performs the best out of YOUR rifle, and start hunting.
