Precision case length gauge for .338 Lapua Magnum with integrated shell holder. Trims cases to 2.706–2.726 inches and squares case mouths for consistent reloading performance.
Reloading precision begins with properly trimmed cases. The Lee Case Length Gauge is engineered to give you fast, accurate trimming while simultaneously squaring case mouths—two critical steps for consistent ammunition performance.
Proper case length directly affects powder capacity, pressure, and accuracy. Cases that are too long can cause excessive pressure; cases that are too short waste capacity. Squared case mouths ensure consistent bullet seating and improved concentricity. This gauge eliminates guesswork and delivers the precision your .338 Lapua Magnum deserves.
Lee Precision tools are trusted by handloaders worldwide for their accuracy, durability, and value. This case length gauge represents the same commitment to precision that has made Lee a leader in reloading equipment for decades.
