Took my PSA 6.5 CM out too start breaking her in. The brass all came out looking rather chewed on. I'm going to give PSA a chance to see what they want to do but if they won't then what are my options? The barrel is stainless.
Chamber polish?

You can look at it as a bonus, less thrust force on the bolt face with that much friction.

Just as an experiment, you should close the gas off (if adjustable) and see what the brass looks like after firing.
I can't help but wonder if those marks are from extraction while still semi sealed to the chamber walls.

I removed the bolt and took a peak....plenty of visible machining in the chamber. I'm going to give PSA a call and see what they say.
I saw that in my .308 PA10 and put some JB on a patch and polished the bore myself and the scoring was noticably reduced. Now that I'm around 150 rounds into break in, cases look normal.
As to @Slacker's theory, I've also come to the conclusion that it is overgassed. One brand of ammo had a section of rim sheared right off. IMI Match brass had a couple bent rims but not until I saw shine from the ejector so I've stepped the charge weight back. I am shooting 180's and using H4895 which shouldn't be so slow as to be the cause of high port pressure. An adjustable gas block is in my future.

It is an unpolished chamber.

Other than killing brass....
Brass is a consumable like bullets powder and primers.
When you buy a budget gun, it costs more in the long run. This chamber issue points to that fact. I like PSA and i want one. But i know a sub $1000 PR gun is a budget price point based on cheap labor costs. Cheap labor is a direct result of your situation and the many other issues with PSA.
Sometimes the hype of a prime brand has a value all its own. Not dealing with issues like you are doing now costs money to you.
pay now, pay later or just know the value of what you have.
