Contradictory Issues?

[SpeyRod]

Sounds like you have a good seating depth. I have many thousands of rounds through gas guns in calibers ranging from 223-6.5-308 and many in between. The high performance bolts we use are often cut to exacting tolerances. What the mfg’s miss is what is mentioned above, final finish on the ejectors. The edges of some of them are left very sharp and they will carve into your brass. I have a couple very accurate guns that leave very clear cuts on the bottom of the brass. I can count my loadings by the cuts.

Polish the edge of your ejector to help with that. Otherwise, accept some rifles will beat up brass. Focus on accuracy and pressure signs other than ejector swipes.

Best of luck!
