Chad, try some different ammo. It sounds like the rounds you're using are two high pressure for the gun. These rifles are timed and tuned to work within certain pressure limits. In other words if it works with standard factory ammo the PMP is putting too much gas through the sytem and the bolt is working too fast. George
