Lee Precision 90158 Case Length Gauge 357 Mag w/ Shell Holder

The Lee Precision 90158 Case Length Gauge is a precision reloading tool purpose-built for the .357 Magnum reloader. This hardened steel gauge provides a quick, accurate way to trim fired cases to the correct overall length and square the case mouth in a single step, helping eliminate the dimensional variations that cause feeding and pressure issues at the press.

Designed for serious reloaders, the gauge is precision-machined to exacting SAAMI specifications from hardened steel, ensuring a lifetime of consistent service. The included shell holder secures the case so it can be trimmed and squared at the same time. To trim, simply chuck the gauge in a hand drill or electric drill, and with the Lee Cutter and Lock Stud (sold separately) or Zip Trim, cases are brought to a uniform length of 1.270 to 1.290 inches per SAAMI spec.
