Pretty sure it has nothing to do with the gun.

I think that is some sort of manufacturing mark on surplus ammo, it's more pronounced on some cases and not detectable on others. I went digging through my stash of plinkin' ammo, the one on the left is headstamped hp 76, the right is fnm 80-60. Again, not noticeable on all (or most) maybe in the ballpark of 10% +-5, I wasn't about to sort through it all.

I did not see any marks like this on the LC stuff or on the annealed SB ammo.

These are 7.62 BTW.

Aaarrrrggghhh, can't get picture to upload, will try again tomorrow, or would be happy to e-mail it to someone who knows what they are doing (apparently I don't)
