[QUOTE="mountainman56, post: 987725, member: 79106"] I don't understand a few things.........first how do you re-chamber a 7mm to a 300 not that it has anything to do with the firing issue? It isn't a trigger problem unless the firing pin doesn't drop at all. Once the sear is released the trigger is taken out of the picture. Since the bolt closes on a no-go gauge it obviously has a headspace issue and the barrel will need to be set back. Also I would disassemble the bolt and check for a bound firing pin spring or excessive lube. Is your friend loading his own cartridges? Any chance he is getting lube into his primers while assembling? 50 plus rounds in one day at the range? [/QUOTE]
