Anyone around the Chattanooga area have 6.5 Creedmoor headspace guages?

Recommended Posts

Posted (edited)

I need to verify if my new Manson Headspace GO gauge is not to spec or if my chamber is actually short. Not closing on a go gauge using 2 different bolts. Bolts spaces good in my 308 barrel. 1 bolt closes on round (but tight) while other does not. I am leaning 70% short chamber on a new Balllistic Advantage barrel, but would like to confirm.

Appreciate any help.

I don't have a gauge but you have an opportunity here. If you want the highest accuracy possible out of this bolt gun, I would take the bolt that does in fact close on a fresh round and do this. Take the firing pin and extractor out of the bolt, put a dab of dykem blue on the recoil face of the bolt lugs. Put a fresh round into the chamber and put the bolt in battery once, remove the bolt and check for equal rub on both bolt recoil lugs. A good percentage of factory bolt/receiver combinations are not individually mated in the factory.  If you see you have more run on 1 lug that the other, You may very well get the "snug functioning of the bolt to go into a smooth battery function by lug lapping the bolt with valve grinding compound. zero headspace is the ultimate headspace on bench guns. Like I said, this problem could be a good thing! Either way, Good Luck with it.
