Rifle is an AR10 that I think is the problem. Rounds are hornady 6.5 creedmoor. I’ve shot a bunch of these rounds (55-65) through another gun and pretty sure it never happened. At least I can’t find any brass to say it did. It’s a pin hole in the primer at firing pin impact point. But it really hammered the firing pin. Loaded the bolt to where it stopped shooting. So I broke the bolt down and figured the symptom but not the cause.
