Firing pin is not chipped, gun has been cleaned meticulously several times and it doesn't seem to help.
Looked like the firing pin was contacting the end of the barrel more than the round so I tried filing a hair off the firing pin (avoiding the part that touches the rim).
I'm wondering if maybe the magazine is contacting the bolt and keeping it from going all the way forward.
Could it be that there is too much room between where the round sits in the bolt and the extractor? Allowing for too much room resulting in insufficient contact by the firing pin?
I will see about loading pictures, basically what is happening is the firing pin is hitting the rim but not enough to fire the round. It's not bad ammo, the problem has persisted through may ammo types. If you press forward on the charging handle every time the the gun will go off every time.
Maybe if I drop a nickle in the back of the receiver it will put more pressure on the spring and fix my problem
