Primers pop - Ammo, Inc. 300 Blackout 155 Grain Boat Tail Hollow Point (BTHP) Centerfire Rifle Ammunition

I have ran through about 100 of the 200 rounds. I have had several failures to fire where I will inspect the round that did not fire and it seems OK then reload and fire it successfully. On another range trip today I had the same experience though after dropping the mag and reloading the normal appearing cartridge I noticed a primer on the bench. I collected all the spent casings and one was missing a primer and another had a primer bulging out. Finally figured out the popped primers are interfering with the action thus causing the failures. I'm reluctant to use the rest of the ammo for fear of damaging my gun with a loose primer floating around in the action. Very disappointing considering this is new factory ammo.
