I thought this was pretty interesting. It happened intermittently, but enough rounds hit to do damage. I was shooing British mil surplus. I didn't think to take a pic of the head stamps before trashing the brass.

I never noticed brass kisses on the factory dust cover in the spot where the brass smackation is occuring.

Should see it after 2K+ rounds.
