still having problems with my mosin
I am just guessing, I have two mosin's, I don't have the problem that you are having, but if I were to apply some speculation to your problem I might think that due to years of using "steel cased ammo" there just might be a hairline ridge around the chamber mouth that would contact the case just about exactly where your pics show the scratches.

Also, using the chamber brush method that you have tried, would not take the ridge down because the bristles are running in line with the ridge.

I would suggest some VERY fine sand paper on a dowel rod, and just sand around the chamber mouth enough to smooth the ridge, Just a thought.
