The Forster .308/7.62 NATO 1.637-Inch Match Gauge (brand part no. HG308-1.6370-SP) is a precision steel headspace gauge ground to a specific 1.637-inch step within the .308 Winchester/7.62 NATO match gauge lineup, used by precision handloaders and gunsmiths to pin down a chamber’s exact headspace rather than just confirming it falls between go and no-go. Forster Products offers this cartridge in a series of fine-graduated match gauges so a shooter can set up ammunition to headspace precisely for their specific rifle, a common step in competitive and long-range handloading. It’s a more specialized tool than a standard go/no-go pair, aimed at fine-tuning rather than pass/fail inspection. Stock it with the rest of our gunsmithing tools and gunsmith supplies for precision reloading work.

Frequently Asked Questions

Who typically uses a gauge like this? Precision and competition handloaders who fire-form or set up brass to match a specific rifle’s chamber as closely as possible.
