Key features

• the set consists of a case length gauge and a case holder (shellholder) for .357 Magnum
• works like a go/no-go gauge: a case that does not need trimming will not be trimmed
• trim by hand or with an electric drill

Usage

The gauge and shellholder are used with the Lee Cutter and Lock Stud or the Lee Cutter with Ball Grip and Lock Stud, or with the Lee Case Conditioning Kit or Zip Trim (sold separately). One cutter serves all calibres with bullets below 12.1 mm (0.475 in).
