Re: OK I need help!
I agree, polishing the chamber is a debatable procedure. I've done it, it cured the two rifles problem, and I have witnessed no ill effects. Varmit Al gives a pretty interesting argument for the benefits on his website, from an engineers point of view.
And I would think everyone would agree, a chamber that is so rough it scratches the brass and/or will not allow extraction, needs to be polished.
