rifle chamber scratching brass

[sapperJ24]

Looking for thoughts on how to remedy this problem. I thought (hoped) it would go away on its own, and that has not happened. Every piece of brass comes out scratched up, sometimes the scratch is deep enough that I would consider it a gouge as you can catch your nail on it. I picked up a borescope to see what was going on and there's some pretty decent gouges in the chamber.

What is the best way to get this chamber cleaned up? Am I good to keep using the brass with gouges, keeping an eye on them of course? Does this have an impact on accuracy?

Have a gunsmith polish the chamber if you are not comfortable doing it. I personally wouldn't worry about the brass, maybe run it through a tumbler and see what it looks like afterwards.

New rifle? I’d get with the mfg about sending it back for them to fix it if so

Echoing EastTNHunter, is it new? If so have the company fix it, if not that should be an easy fix for a gunsmith.

Probably not new enough anymore. I should have reached out earlier.

Take a fired case, resize it and make it a little smaller. Drill out primer and then thread it. Put a bolt in the threaded hole. Chuck up in a drill. Put very fine lapping compound on the case. Then insert and spin. Do small amounts. Clean very, very well when done.
