The Lyman Case Trimmer Pilot #39 (Manufacturer Part Number: 7822003, also known as LY-CTP39) is a precision-machined reloading accessory designed to assist handloaders in maintaining accurate cartridge case lengths. Specifically engineered for .40 S&W and 10mm Auto cartridges, this pilot fits securely into the mouth of resized brass cases measuring between .397 inches and .400 inches in diameter. Its primary function is to align the case mouth perfectly square with the cutter head of your trimmer. By providing internal support, the pilot prevents the brass neck from collapsing or deforming under cutter pressure, resulting in clean, uniform trims that meet strict SAAMI specifications. As a purely mechanical, non-powered steel component, this pilot requires no electrical power, making it fully exempt from Australian SAA and RCM compliance markings. It functions seamlessly within both manual setups and power-adapted Lyman trimming systems used across Australia.

Key Features of the Lyman Pilot #39:

  • Caliber-Specific Precision: Tailored precisely for .40 S&W and 10mm Auto calibers to ensure a snug, wobble-free fit inside the case neck.
  • Perfect Alignment: Centers the cartridge case with the cutter shaft, ensuring an even, flat cut across the case mouth for improved chambering and accuracy.
  • Structural Support: Prevents brass deformation, neck collapse, or distortion during the trimming process.
  • Hardened Steel Construction: Machined from high-durability steel to withstand friction and wear over thousands of trimming cycles.
  • Universal Integration: Designed to fit all standard Lyman Case Trimmers, including the Lyman Universal Case Trimmer.
  • No Electrical Requirements: A passive mechanical tool that requires no 240V power, cords, or Australian plugs, simplifying your reloading bench setup.
