[QUOTE="Hired Gun, post: 738764, member: 1290"] The bolt nose recess dimension won't tell you much. The distance the cartridge sticks out of the barrel or chamber is dependent on the action used. Some sit in a recess so the cartridge is near flush. Head space is still measured with gauges and a depth gauge. With a cone nose bolt you measure from the shoulder of the barrel to the bolt face and compare the shoulder to Go-Gauge to determine headspace. What are you working on? [/QUOTE]
