[QUOTE="Bart B, post: 505822, member: 5302"] You probably could, but the chamber reamer may need an oversize pilot. If the 7 Rem Mag barrel's got over 800 rounds through it, the throat may well be enlarged such that an oversize pilot is needed to center the new chamber on the bore.. After this is done, the accuracy probably won't be any better than the original chamber produced. And it'll wear out faster 'cause more powder's burned for each shot. I'd stick with the original chamber until the barrel's worn out and accuracy's no longer what you want. Then rebarrel to the larger round. I'd check magazine length to be sure the new ammo both fits and feeds reliably from it. [/QUOTE]
