I haven't heard back from the smith but he shipped me the gun without charging me for it, just sent an invoice. Does anyone have a recommendation for a fix for any of the listed isses? Will polishing the chamber get rid of the longitudinal scratches on the case?

I went and shot the rifle today to see if I could replicate the scratches and dents. Cases do come out scratched but not dented. I think the dents below the shoulder may come from feeding them through the gun but cannot say for sure until I load some up and go try it again.
