[QUOTE="bigedp51, post: 1887481, member: 28965"] Below the cheap bastards headspace gauge. Measure a case from the case mouth to the base of the case and write it down. [IMG]https://i.imgur.com/SgwqgaU.jpg[/IMG] Next just using your fingers start a fired spent primer into the primer pocket. [IMG]https://i.imgur.com/oNIvIiX.jpg[/IMG] [IMG]https://i.imgur.com/zQxlYGp.jpg[/IMG] Now chamber this test case and let the bolt face seat the primer and remove the case. Next measure the case again from the case mouth to the base of the primer and write it down. Now subtract the first case measurement from the second and this will be your actual head clearance. If I measure this case in my adjusted Hornady Cartridge Case Headspace gauge it will tell me my chambers actual headspace. All a actual headspace gauge tells you is if the bolt closes or will not close. Below a set of nine .308 headspace gauges in .001 increments that gets you closer to actual chamber headspace. [IMG]https://i.imgur.com/rNoQCt0.jpg[/IMG] And since I'm a cheap bastard a case and a fired primer is cheaper than headspace gauges and tells you more. [/QUOTE]
