[QUOTE="bigedp51, post: 1405022, member: 28965"] If you have a headspace gauge and a Hornady cartridge case headspace gauge you can determine the chambers actual headspace length. Below a Colt Field headspace gauge at 1.4736 [IMG]https://i.imgur.com/F81aB6g.jpg[/IMG] Below the same headspace gauge in my adjusted Hornady gauge. [IMG]https://i.imgur.com/kkoU6og.jpg[/IMG] Below a fired case in the adjusted Hornady gauge that is very close to actual chamber headspace length. [IMG]https://i.imgur.com/OJqNmQH.jpg[/IMG] Before anyone want to argue, a headspace gauge only tells you if the bolt will close between the GO and NO-GO gauges and not actual chamber headspace. Below a .308/7.62 headspace gauge set in .001 increments and with these gauges you still only know to approximately .001 your chambers headspace length. [IMG]https://i.imgur.com/rNoQCt0.jpg[/IMG] You can also put a fired spent primer in a fired case using just your fingers. And then chamber the case letting the bolt face seat the primer and measure the case again. The amount the primer is protruding will be any spring back of the case shoulder after firing. Bottom line my vernier calipers are accurate to .0005 so any measurement will be plus or minus .0005. And close enough for the average reloader that doesn't have headspace OCD. [/QUOTE]
