POST #19 Figure is the "Cartridge". Go to Link, it's SAAMI PDF auto download. Open it, Your's is at page 98. Top figure is cartridge (ignore), bottom figure is "CHAMBER" on bottom Left is the Key. "X" inside "○" denotes "HEADSPACE" measurements between corresponding lines with arrow tips. From bottom/base of the gauge to the First sharp edge then mid shoulder angle. "Go" number you provided (on gauge) 1.079 is .0001 Larger than SAAMI listed Minimum of 1.0789. Its a miniscule difference but it's there none the less and more than likely the gauge and or number is just "Rounded Up". Gauge should still be measured to verify its true size verse above numbers and tried again "with Marking" with the stripped bolt face and clean surfaces.
