Lyman Pro Maximum Cartridge Gauge 9mm Luger Stainless Steel

The Lyman Pro Maximum Cartridge Gauge is a precision reloading tool used to verify the critical dimensions of a 9mm Luger cartridge - case mouth diameter, case length, and overall cartridge length - so each round is confirmed in spec before it ever reaches a finished load. Inspired by the Lyman Pro Die Sets, the gauge is precision machined from corrosion-resistant stainless steel for a long, rust-free service life, with milled outside flats that make it easy to pick up, set down, and handle on the reloading bench.

Caliber-specific by design, this Pro Maximum Gauge gives the 9mm Luger reloader a dedicated reference that matches the dimensions of the cartridge. A resized or loaded case drops into the gauge and the mouth, body, and overall length can be checked at a glance - a fast, repeatable visual confirmation that is faster and cleaner than tumbling cases back out of a press to measure each one with calipers.

Sized and finished for a lifetime of 9mm work, this Pro Maximum Cartridge Gauge belongs on the bench of any serious 9mm Luger handloader who wants to verify case trim length and mouth sizing before assembly.
