The Forster Headspace Gauge in .22-250 Remington NO-GO (brand part no. HG2225N) pairs with a GO gauge to bracket a .22-250 chamber’s exact headspace. Headspace is the distance between the face of the breech and the base of a chambered cartridge, and it is one of the most safety-critical measurements on any rifle. Excessive headspace lets brass stretch or rupture on firing, which can send gas blasting rearward toward the shooter, so gunsmiths rely on precision gauges rather than guesswork to verify a chamber is cut correctly. Forster builds these gauges to painstaking tolerances so that test is one you can trust.

Frequently Asked Questions

What does it mean if my bolt closes on this NO-GO gauge? If the rifle’s bolt closes on a GO gauge, the chamber will safely accept ammunition built to SAAMI industry-standard dimensions. If the bolt closes on a NO-GO gauge, the chamber may already have excessive headspace, and if it closes on a FIELD gauge the chamber is dangerously close to, or already beyond, the maximum SAAMI-specified size. Most gunsmiths aim to keep a chamber cut somewhere between the GO and NO-GO dimensions.

Should I use this gauge alongside a GO gauge? Yes, using both lets you confirm the chamber falls between the GO and NO-GO dimensions rather than checking only one boundary.
