Lyman an innovator in the field of case preparation and reloading has added several new calibres to their popular Ammo Checkers Line. Ammo Checkers are gauges that verify the quality and consistency of both reloaded and factory ammo.

They are machined from solid aluminium and cut with custom tooling to SAAMI minimum chamber tolerances. Just insert a cartridge into the gauge and if it fits, it will chamber in a firearm. Each gauge is clearly marked for calibre and is anodized in bright orange.
