Lyman's Multi-Caliber Ammo Checkers are very popular with reloaders. Due to customer demand, Lyman now offers gauges with 8 chambers, all of the same caliber.

These gauges allow reloaders to take multiple cartridges straight off the press and check them as they load. If they fit, the reloaded ammo will fit in the chamber. Like Lyman's other multi-caliber blocks, these are machined from solid 6061 aluminum and cut to SAAMI minimum chamber tolerances using custom tooling.

A must-have for any semi-auto shooter, these easy-to-use "GO" gauges ensure the quality and dimensional accuracy of your reloaded ammo.
