Lee Trimmer Gauge .38-55 Winchester Case Length Gauge & Shell Holder

The Lee Trimmer Gauge for the .38-55 Winchester is a precision case length gauge and shell holder designed to make trimming rifle brass quick, easy, and repeatable. Lee machines this compact gauge from steel and calibrates it to cut each case to the proper trim-to length for the .38-55 Winchester cartridge, helping reloaders maintain consistent overall case length for safer feeding and improved accuracy.

Beyond serving as a length gauge, the unit also functions as a shell holder, gripping the case firmly while you square the case mouth and trim the brass. It is designed to be used with a Lee cutter drive system, including the Lee Cutter and Lock Stud, Ball Cutter, or Zip Trim, so it drops right into a standard Lee hand-trimming setup or a powered case-prep station.

By keeping cases trimmed to specification, this gauge helps reloaders avoid the pressure spikes and feed problems that come from over-length brass, making it a simple but essential reloading accessory for anyone loading .38-55 Winchester ammunition. Its small footprint, durable steel construction, and caliber-specific fit make it a staple of the Lee case-prep lineup.
