Lyman Ammo Checker Small Rifle Cartridge Gauge 204 Ruger / 22 Hornet / 223 Rem / 22-250 / 300 Blackout

The Lyman Ammo Checker is a precision cartridge gauge purpose-built for small rifle calibers. Cut from solid blocks of 6061 T6 aircraft-grade aluminum with custom tooling to SAAMI minimum chamber dimensions, this gauge lets reloaders quickly confirm that their handloads will chamber safely and reliably before heading to the range or field.

This Small Rifle model covers five popular varmint and tactical cartridges in a single block: 204 Ruger, 22 Hornet, 223 Remington, 22-250 Remington, and 300 Blackout. Each chamber is clearly engraved with its caliber, and the gauge holds up to 6 cartridges at a time for fast, bench-top checking.

Compact and built to last, the Lyman Small Rifle Ammo Checker measures 2.20" x 3.80" x 7.45" and is an essential reloading bench tool for varmint hunters, AR-15 shooters, and precision handloaders who want to verify ammunition dimensions against factory-spec chamber tolerances.
