Thread: Brass on bolt face

I assume the Hornady case is on the right, based on the PPU/Highland anneal mark.
Bit of a bulge in the case side wall.
'Could be' pressure related and that might fit in with the brass on the bolt face?
Maybe just shoot the Highland and see if its still an issue?

Yep Hornady on the right. I'll try that next time I'm at the range cheers

Nothing in your pics suggests any pressure issue to me. If all the brass looks similar the factory ammo loads should be perfectly safe.
I'm guessing the transfer of brass residues to the bolt face is somehow related to the parkerising.

yeah, I can't see any signs of pressure in those photos even the primers look perfect no flatting
