Lyman Ammo Checker Small Rifle Gauge

The Lyman Ammo Checker – Small Rifle Gauge is a precision-machined chamber gauge designed to verify the quality, consistency and dimensional accuracy of both reloaded and factory small rifle ammunition. Manufactured from a solid block of 6061-T6 aircraft-grade aluminium and cut to SAAMI minimum chamber specifications, it provides a quick pass/fail check to ensure your ammunition will chamber correctly before heading to the range or field. Simply drop a loaded cartridge into the gauge—if it fits correctly, it's ready to shoot with confidence.

The Small Rifle Ammo Checker supports six of the most popular small rifle cartridges in a single compact gauge, including .204 Ruger, .22 Hornet, .223 Remington, .22-250 Remington, .300 AAC Blackout and 7.62×39mm. Each calibre is clearly engraved for easy identification, while the bright orange anodised finish makes the gauge easy to locate on any reloading bench. It's an essential quality-control tool for reloaders seeking reliable chambering and consistent ammunition performance.
