Forster Headspace Gauge, .22-250 Remington GO

The Forster Headspace Gauge in .22-250 Remington GO (brand part no. HG2225G) gives gunsmiths and serious handloaders a precise way to confirm a .22-250 chamber falls within SAAMI industry-standard dimensions. Every gunsmith knows that a headspace gauge is the most reliable way to confirm the length of a rifle chamber. Headspace is the distance between the face of the breech and the base of the cartridge when the action is closed, and excessive headspace can be dangerous as well as harmful to accuracy: unsupported brass fired in a chamber with too much headspace can rupture, sending gas rearward like exhaust from a rocket. Forster gauges are built to painstaking tolerances for exactly this kind of check.

Frequently Asked Questions

What does it mean if the bolt closes on this 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.

Is this an essential tool after rebarreling a .22-250? Yes, most gunsmiths check headspace with a GO gauge as a standard step any time a new barrel is chambered.
