[QUOTE="257RobertsMan, post: 1852386, member: 111366"] Please correct me if I'm wrong, is this not the same as using a 3-4 fire formed piece of brass that has been necked sized only, partially inserting a spent primer that has some resistance to entering the primer pocket, inserting it into the chamber and slowly closing the bolt? Will this not tell you the maximun lgth from the contact point of the cartridge shoulder to the bolt face? Is that not the max? Any longer and the bolt will not close (same as a no go gauge). Or technically if the brass shoulder is against the front of the chamber and the primer is protruding out of the primer pocket, measure the protrusion of the primer and that measurement is called Headspace? Or am I looking at this wrong? [/QUOTE]
