If you're going to the expense of a custom build spend an extra $150 and put a muzzle break on it. Get a thread protector if you don't want the break on it all the time. I think the recoil of the 300 WM is tolerable a 300WBY is pretty stout and a 300RUM is just too much to handle comfortably. Do the break and don't worry about recoil or scope cut
