Lee Case Length Gauge 10mm Auto w/ Shell Holder

The Lee Case Length Gauge for 10mm Auto is a precise, easy-to-use two-piece reloading tool that trims brass cases to a uniform length and squares the case mouth in a single step. Each gauge is machined from hardened steel with a silver finish and is caliber-specific, designed to bring fired 10mm Auto cases back to the proper trim length of .982 to .992 inches.

This gauge functions as part of Lee's case-prep system: the shell-holder end captures a single brass casing while the opposing gauge body works with a Lee Cutter and Lock Stud or Zip Trim to trim and deburr the case mouth simultaneously. The result is consistent case length, squared mouths, and reliable chambering round after round.

Included in this 2-piece set is the 10mm Auto case length gauge and a matched Lee shell holder, giving reloaders everything needed to begin case prep without buying extra components. Compact and lightweight at roughly 0.06 lbs, it is an essential bench tool for any 10mm Auto reloading setup.
