Lee Case Length Gauge and Shell Holder for .243 WSSM
The Lee Case Length Gauge (model 90389) is an essential reloading tool for shooters who demand precision in their ammunition preparation. This hardened steel gauge provides a fast, accurate method for trimming brass cases to proper length while simultaneously squaring the case mouth—a critical step for consistent, reliable ammunition.
Key Features
- Precision Engineering: Crafted to tight SAAMI specifications for maximum accuracy
- Hardened Steel Construction: Built for a lifetime of reliable performance
- Dual Function: Trims cases and squares case mouths in one operation
- Caliber-Specific Design: Engineered specifically for .243 WSSM cartridges
- Trim Range: Works with cases from 1.650 to 1.670 inches
How It Works
The gauge works in conjunction with the Lee Case Trimmer Cutter and Lock Stud (or Zip Trim system). The included shell holder securely positions your brass case during the trimming operation, ensuring consistent results every time. This combination of tools helps eliminate variables that can affect ammunition performance.
Why It Matters
Proper case length is fundamental to safe, accurate reloading. Cases that are too long can cause excessive pressure; cases that are too short may not chamber properly. Squaring the case mouth ensures proper bullet seating and consistent cartridge overall length. These precision tools give you control over these critical variables.
