Lyman Ammo Checker Multi Gauge

Use the Lyman Ammo Checker Multi Guage to confirm loaded rounds will chamber reliably. These gauges check the quality and chamber-fit of both reloaded and purchased ammunition so you can identify “no-go” rounds before they reach the firearm.

• Machined from solid blocks of 6061 T6 aluminium and cut to SAAMI minimum chamber dimensions for consistent, repeatable gauging.
• Three designs—Handgun, Large Rifle, and Small Rifle—cover most common calibres; each gauge accepts a variety of rounds so one tool serves multiple cartridges.
• Calibres are clearly engraved and the bright orange anodized finish makes the gauges easy to find on a bench.
• Simple drop-in test: if a loaded round fits the gauge, it will fit the gun’s chamber according to the supplied dimensions.

This tool is intended for quick verification of chamber fit and feed consistency for a wide range of handgun and rifle calibres. Use it to sort and identify rounds that do not meet the specified chamber dimensions before loading or use.
