I've got a Remington 700 rebarreled with a takeoff factory .308 24R bbl. I picked the barrel up cheap on here from prariegoat. It's an absolute tack driver, but it's got a chamber that produces fired brass marked with it's particular chamber irregularities, much like the OP's. It's one of several 308's in the safe. I never need to worry about keeping track of which brass came from that rifle.
