This is a learning curve for me as well so a bore scope may have just elbowed its way onto the list of things to get. Even an old dog can learn a new trick now and then.

I was also getting marks like that on my projectiles and I instantly thought rifling but lots of checks made and no change in seating depth had me scratching my head it was scratching on the ring I chased my tail for a bit changed nothing apart from removing the ring and everything came right again . The only rifle iv dealt with a true carbon ring on easy maintenance has seen it become a past issue
