Lee Case Length Gauge & Shell Holder 6mm ARC

The Lee Case Length Gauge & Shell Holder is a precision reloading tool purpose-built for the 6mm ARC cartridge. It combines a fixed-length gauge with an integrated shell holder, giving reloaders a fast, repeatable way to bring fired cases back to a uniform trim length and square the case mouth during case prep.

Machined from hardened steel for long service life, the gauge sets the exact trim length and supports the case while you run the cutter. The shell holder drops straight into your press or hand-trimmer setup and is designed to work with the Lee Cutter and Lock Stud, the Case Conditioning Kit, or the 3-Jaw Chuck to produce square, consistent case mouths ready for resizing and charging.

Whether you are prepping new brass for a precision 6mm ARC rifle build or maintaining uniformity across fire-formed cases, this gauge/holder combo delivers the controlled trim length and clean case mouth that accurate handloads require. Lee part number 92030.
