Lyman’s new Ammo Checkers check the quality and consistency of both reloaded rounds and purchased ammo. A must for any auto shooter for easy and consistent feed. You can’t afford misfeeds, so get the easiest “no-go” gauge available today!

These Ammo Checkers are gauges that allow a reloader to quickly confirm that their ammunition will fit in their chamber. Machined from solid blocks of 6061 T6 aircraft grade aluminium and cut with custom tooling to SAAMI minimum chamber dimensions. Ammo Checkers are available in three designs covering most common handgun and rifle calibres. One gauge will work with a variety of calibres. Just drop your loaded rounds in the ammo checker, and if the round fits into the gauge, it will fit in the gun’s chamber. Each calibre is clearly engraved on the gauge. Bright orange anodizing makes them easy to find on your reloading bench.

This small rifle gauge checks: 204 Ruger, 22 Hornet, 223 Rem, 22-250, 300 AAC Blackout, 7.62 x 39
