Dimpled Primers

[LR1955]

Ah....I see. I didn't realize you were talking about PRIOR to firing. In that case Drifter is 100% correct. I've seen it if I leave my primers a tiny bit high when seating primers. Never noticed it in factory ammo.

Bill:

Very common with issued ammunition and the M-16 / M-4 series that uses an inertial firing pin. What it looks like is very small and although it does put a slight dimple in the primer, it is far from being dangerous unless you load and unload that same cartridge many times.
