Forster 8mm Mauser Belted and Rimmed Headspace Gage, No-Go

The Forster Products Belted and Rimmed Headspace Gage for 8mmx57 Mauser (brand part no. HG8X57N) checks for excessive headspace on classic Mauser-pattern rifles, a caliber where correct chamber length is especially important given how many surplus and sporterized actions are still in circulation. Headspace is the distance between the face of the breech and the base of a chambered cartridge when the action closes, and excessive headspace can be dangerous and can hurt accuracy. The gauge measures 1.88 inches, sized specifically for the 8mmx57 chambering.
