The Forster 220 Swift Go Gauge (brand part no. HG0220G) is a precision steel headspace gauge sized for the 220 Swift, a high-velocity varmint cartridge that still shows up in plenty of bolt-action rebuilds and custom rifles. Forster Products machines it to a fixed 1.806-inch length representing the minimum acceptable headspace; the bolt should close freely on this gauge in a correctly finished chamber. It works alongside a no-go gauge as the standard pair used to confirm proper headspace on a new build or rebarrel. Stock it with the rest of our gunsmithing tools and gunsmith supplies for precision rifle work.

Frequently Asked Questions

Why does a varmint cartridge like 220 Swift need careful headspace checking? Its high pressures and velocities make correct headspace especially important for case life and consistent accuracy.

Do I need this gauge for a factory rifle? It’s primarily used during custom barrel work, rebarreling, or gunsmith verification rather than routine use on an unmodified factory rifle.
