[QUOTE="dsmhero, post: 1958973, member: 81510"] I have not shot the factory Hornady load in my rifle yet. I will look at the fresh cases in a few. I think you are correct in the head CLEARANCE being off(breech face to case head). That would account for the primer being force back and flattened without actual overpressure. I had a gunsmith take a look at it. The GO gauge fit, but required ~0.013" worth of "shims" to find any resistance on bolt close. I am assuming this is corroborating the head clearance issue. I will be contact Seekins shortly. Please correct me if I am wrong. [/QUOTE]
