Lee Precision 90135 Case Length Gauge 30 M1 Carbine

The Lee Precision 90135 Case Length Gauge is a two-piece reloading accessory purpose-built for the 30 M1 Carbine cartridge. It combines a precision case length gauge with a matched shell holder to give handloaders a quick, repeatable way to trim fired brass back to the correct overall length and square the case mouth in a single setup.

Machined from durable steel with a silver finish, the gauge is cut to bring cases to a final trim length of 1.280 to 1.290 inches. It is designed to work in conjunction with the Lee Cutter and Lock Stud or the Zip Trim system, letting the reloader square the mouth and bring over-length cases back into spec without the need for extra fixturing.

Lee case length gauges are caliber-specific, and the 90135 is cut exclusively for the .30 M1 Carbine case. The included shell holder is matched to the gauge, holding the case in proper alignment during the trimming pass for consistent results on every round.
