Lee 90034 Case Length Gauge 300 WSM Steel w/ Shell Holder

The Lee Precision 90034 Case Length Gauge is a two-piece steel trimming and squaring tool sized specifically for the .300 Winchester Short Magnum (300 WSM) cartridge. Part of Lee's proven Case Length Gauge series, this gauge gives reloaders a fast, accurate way to bring fired brass back to factory trim length while simultaneously squaring the case mouth in a single pass.

The gauge is precision-machined from steel with a silver finish and accepts a single brass casing at a time. It trims 300 WSM cases to the recommended length range of 2.080 to 2.100 inches, helping maintain safe, consistent ammunition and reliable chambering. When used with Lee's matching Cutter/Lock Stud (or Zip Trim system), the gauge squares the case mouth as it trims, eliminating the separate deburring step that slower methods require.

This listing includes both the case length gauge and the matching shell holder, so the tool is ready to pair with Lee's handheld or press-mounted trimming setups right out of the package. The shell holder secures the .30 caliber / 300 WSM case during trim and square operations, holding it perfectly aligned for clean, repeatable results.

A compact, economical bench tool, the Lee 90034 is an essential piece of reloading equipment for any 300 WSM shooter who trims their own brass.
