I'm wondering how one goes about getting very similar chambers in two different rifles...at lease similar enough to exchange brass between the two. My idea is to have a hunting and a target rifle set up in 280AI so that I can fire form brass out of the hunting rig and shoot the ff'd brass from the target rig. Sort of even the barrel wear out in my mind as I don't tend to put a lot of rounds through hunting only rifles. Seems to me I'd want to have the chambers cut at the same time with the same reamer, but I'm curious if this is even necessary.
