If you have a 7mm Rem Mag, and want to change it to a 264 Win Mag (I don't know why anyone would want to do that), then buy a new barrel, and the builder will cut, crown, and chamber the new pipe and fit it to the action. So, yes, it's that simple. Chamber accordingly, meant, to whatever you want so long as it matches the action and bolt face.
