Lyman Pro Maximum Cartridge Gauge 45 ACP

The Lyman Pro Maximum Cartridge Gauge for 45 ACP (Lyman part no. 7705003) is machined from corrosion-resistant stainless steel to give competitive shooters and high-volume reloaders unmatched precision when checking pistol ammunition. It verifies case length, diameter, and overall cartridge length in a single check, catching any round that would otherwise cause a chambering issue. Flat sides keep the gauge from rolling off the bench, and built-in O-rings give it a secure grip in hand. Serious 45 ACP reloaders use this gauge to confirm every round meets spec before it goes into a magazine.
