Lee Precision case length gauge for .243 Winchester delivers precise trimming to 2.025–2.045 inches and squares case mouths. Hardened steel construction built to SAAMI specifications for consistent reloading performance.
Precision reloading begins with properly prepared brass. The Lee Case Length Gauge and Shell Holder system gives you the tools necessary to trim your cases to exact specifications and square the case mouth—two critical steps for consistent ammunition performance.
Consistent case length is fundamental to ammunition reliability and accuracy. Cases that are too long can cause feeding problems and excessive pressure; cases that are too short waste the potential of your reloads. Squaring the case mouth ensures proper bullet seating and consistent neck tension.
This gauge takes the guesswork out of case preparation, allowing you to produce ammunition that performs predictably downrange.
