I'm installing a Remage barrel in 6.5 Creedmoor. So I've threaded the receiver onto the barrel with the Go Gauge inserted. This should be SAAMI minimum headspace. Then I inserted the No Go gauge and verified the bolt won't close. I've read you should then back off the receiver .003 so you're not right at minimum. However, in researching the Creedmoor drawings and taking my own headspace measurements with my Hornady HS gauge and calipers these are the numbers I come up with. SAAMI Chamber min HS - 1.541 SAAMI cartridge min HS - 1.5368 Manson Go Gauge - 1.533 Manson No Go Gauge - 1.539 New unfired Lapua brass - 1.530 Given these measurements, should I install the barrel at minimum headspace and leave it there? Seems I would have .003 clearance with Lapua brass right there.
