I want to re barrel my 7mm rem mag I use it mostly for whitetail but I want to use it on bigger game as well like elk and bear.

so my question is if I get the 1-9 twist in the barrel that should work well with the new heavier rounds ill use for big game (180gr) but will it work well with the lighter rounds I use on white tail.....the rounds I like to use on whitetail is 140gr

whats your thoughts
