The Lee Precision Case Length Gauge and Shell Holder for .38 Super (part no. 90217) is a two-in-one case-prep tool built for reloaders who load this cartridge regularly. One end gauges and squares the case mouth while the other holds the case steady as a shell holder, so a single tool handles both jobs during trimming. It is machined from hardened steel to SAAMI-correct dimensions, giving you a trim reference that will not drift after hundreds of cases. Reloaders who load .38 Super in volume use this exact gauge and shell holder pairing every session to keep case length consistent and chambering reliable.

Key Specifications

• Sized specifically for .38 Super brass, so the gauge and shell holder register correctly on this cartridge alone.
• Built from hardened steel for a lifetime of repeated trimming cycles without the tool itself wearing out of spec.
• Manufactured to tight SAAMI tolerances so trimmed cases chamber consistently across your rifles or pistols in this caliber.
• The shell holder half locks the case firmly in place while you work the trimmer cutter, preventing slip during the cut.
• The case length gauge half squares the case mouth at the same time it trims, saving a separate deburring pass.
• Weighs approximately 0.8 oz shipped, light enough to keep several on the bench or in a range bag.

Frequently Asked Questions

Do I need anything else to trim brass with it? Yes, it is used together with a Lee Case Trimmer Cutter (sold separately) to actually cut the case to length.

What is it made of? Hardened steel, so it holds its size through repeated case-prep sessions.
