Lyman Single Caliber Ammo Checker .300 AAC Blackout
Lyman's Ammo Checkers are precision "Go/No Go" gauges that allow a reloader to quickly confirm that their ammunition will fit in their chamber. Gauges are cut to SAAMI (or CIP for non-SAAMI calibers) minimun chamber dimensions. Just drop your loaded rounds in the Ammo Checker, and if the rounds fit into the gauge flush or below the top surface, they will chamber.
Lyman’s multi-caliber Ammo Checkers have proven to be extremely popular with reloaders since their introduction last year. Ammo Checkers are gauges that verify the quality and consistency of both reloaded and factory ammo. They are machined from solid aluminum and cut with custom tooling to SAAMI minimum chamber tolerances. Just drop your cartridge into the gauge and if it fits, it will chamber in your gun.
