The Forster 6.5 Creedmoor NO GO Headspace Gage (Forster part no. HG65CRN) measures headspace, the distance between the breech face and the base of the cartridge when the action is closed, on a rimless 6.5 Creedmoor chamber. Excessive headspace is a real safety issue: unsupported brass fired in an over-headspaced chamber can rupture and blow gas rearward toward the shooter. Forster machines this gauge to exacting tolerances so a gunsmith or serious handloader can confirm exactly where a chamber falls against SAAMI specification before it ever gets fired.

What is headspace? Headspace is the distance between the face of the breech and the base of the cartridge when the action is closed; excessive headspace is a safety and accuracy concern.
