This Forster Rimmed & Belted Headspace Gage (brand part no. HG8X57F) is cut to FIELD length for the 8mmx57 Mauser cartridge, measuring 1.884 inches. If a rifle’s bolt closes on a FIELD gage, the chamber is dangerously close to or beyond SAAMI’s maximum safe headspace, so this gage serves as a critical safety check rather than a fitting tool.
