[QUOTE="rpol98, post: 2593221, member: 122310"] the ring marking on the brass, do they go all around, or just along one side? my guess, if they go all around, then rough chamber. but if they're just on one side, I've seen markings like that due to a sharp bevel at the edge of the feed cone, entrance to the chamber. probably on the bottom edge, although it could be the top. depends on how the round comes off the mag and gets launched up the feed ramp into the feed cone to settle into the chamber. but check for a sharp edge, bevel at the feed cone. might see a lot of brass scraped off at the edge, witness marks. just my 2 cents.
