Precision case length gauge for .38 Special brass. Trims cases to 1.135–1.155 inches and squares case mouths. Hardened steel construction built to SAAMI specifications.
Reloaders who demand precision understand that case length directly affects accuracy and safety. The Lee Case Length Gauge provides a fast, accurate method to trim your brass cases to proper length while simultaneously squaring the case mouth—two critical steps in the reloading process.
The gauge works in conjunction with the Lee Case Trimmer Cutter and Lock Stud or Zip Trim system. Simply insert your case into the shell holder, position it in the gauge, and trim to the proper length. The design ensures consistent, repeatable results shot after shot.
Proper case length is fundamental to safe, accurate ammunition. Cases that are too long can cause excessive pressure; cases that are too short may not chamber correctly. Squaring the case mouth ensures proper bullet seating and consistent velocities. This gauge takes the guesswork out of both operations, giving you the confidence that comes from precision reloading.
