Circular marks on the brass, or running the long way ?
Either way if you polish the chamber it may go away....
400 grit to start, finish with 600, or close to it.....

Lengthwise. What do I use to polish it?

I would have thought they would be circular, but any marks should be removed..
A short piece of dowel rod the shape of the chamber as close as you can get it, split so it will hold a piece of wet-dry 400 grit paper oiled up good and spin it in the chamber very carefully.... keep it oiled up good... A few minutes should have it ready for 600 grit, keep that oiled good too. Clean the chamber with alcohol real good and see if it helped when you shoot it again...

You may want to verify how much primary extraction you're getting before you start polishing the chamber. -Al

If it has been leaving marks on the brass it still needs to be polished so it don't.

It is on its way back from Sharp Shooter Supply. He polished the chamber and the dies. I will report back when I shoot it.
