The Lyman Pro Maximum Cartridge Gauge for 9mm (Lyman part no. 7705000) is machined from corrosion-resistant stainless steel to give competitive shooters and high-volume reloaders precise verification of their pistol ammunition. It checks case length, diameter, and overall cartridge length in a single pass, catching any round that would cause a chambering problem before it happens. Flat sides keep the gauge from rolling off the bench, and O-rings give it a secure grip in hand. With 9mm being among the highest-volume calibers reloaded, this gauge lets shooters confirm consistency across large batches quickly.
