Ok I've chambered a few barrels now and have had great results. Now I got a bore scope and see they are great except for some marks in the neck and free bore. From what I can tell is they must be from the time I stopped the lathe to pull the reamer out for the last time And it tight and not so easy to take strait out. So how do you guys finish and take your reamer out without this issue. It seams to be just cosmetic and not do any harm.
