Lyman’s multi-caliber Ammo Checkers have been extremely popular with reloaders. Now based on demand from our customers, Lyman is adding gauges having multiple chambers with all being of the same caliber. These gauges allow reloaders to take multiple cartridges right off the press and check them as they go. If they fit, they will chamber in your gun. These are machined from solid 6061 aluminum and cut with custom tooling to SAAMI minimum chamber tolerances. A must for any semi-auto shooter, these easy to use “GO” gauges ensure the quality and consistency of your reloaded ammo. Each gauge is clearly marked for caliber and is anodized in a bright orange color so that they will be easy to spot on your reloading bench.
