Lee Precision case length gauge for .303 British with shell holder. Trims cases to 2.202-2.222 inches and squares case mouths for consistent reloading performance.
Precision reloading demands precision tools. The Lee Case Length Gauge and Shell Holder is engineered to deliver exactly that—a fast, accurate method for trimming your brass cases to proper length while simultaneously squaring the case mouth.
The gauge works in conjunction with Lee's Case Trimmer Cutter and Lock Stud or Zip Trim system. Simply insert your case into the shell holder, position it in the gauge, and trim to the proper length. The design ensures both efficiency and repeatability—essential qualities for handloaders who demand consistency.
Uniform case length is fundamental to safe, accurate ammunition. Cases that vary in length can produce inconsistent pressures and velocities. By maintaining proper case dimensions, you ensure your loads perform as intended, shot after shot.
