The Forster Headspace Gage for 6.5 Creedmoor, GO-length rimless (brand part no. HG65CRG), is a precision go/no-go style gauge built to check the most reliable measurement for testing a rifle chamber’s length: headspace. Headspace is the distance between the breech face and the base of the cartridge when the action closes, and excessive headspace is a genuine safety concern, since unsupported brass fired in an over-length chamber can rupture and vent gas rearward toward the shooter. Forster manufactures its headspace gages to exacting tolerances specifically because a shooter’s safety depends on the result. If a rifle closes on this GO gage, the chamber will accept any ammunition manufactured to SAAMI industry-standard specifications, giving a gunsmith or handloader a reliable pass/fail check before that rifle goes back into service.
