Primer strike from chambering

[XUSMICO]

With a Ranger thumbnail, I'm surprised. This is a normal. Do some research.
looking closely one can see multi strike dimples. this IS not dangerous but in soft commercial primers it can damage the compound or anvil resulting in a FTF.
never use training/range rounds for duty. When you rotate mags and do ammo check, dimpled rounds go to training stock to confirm zero with duty loads.
