Hornady Case Trimmer Pilot #10 - .312"

The Hornady Case Trimmer Pilot #10 in .312" diameter is a precision reloading accessory engineered for shooters who demand consistent case preparation. This trimmer pilot works with both the Hornady Cam-Lock Case Trimmer and the original Hornady Case Trimmer, providing caliber-specific trimming solutions for handloaders preparing rifle or pistol brass. The .312" diameter specification matches rounds in the .308 Winchester family and similar caliber classes, ensuring proper case neck guidance during the trimming process.

Hornady manufactures this pilot using premium-grade materials selected to withstand repeated use across hundreds of reloading cycles without wear or dimensional drift. The compact form factor—weighing just 0.05 lbs and measuring 1.9 x 1.2 x 3.05 inches—allows for straightforward installation and removal from compatible trimmer assemblies. Precision-manufactured tolerances ensure the pilot centers brass cases concentrically, eliminating uneven case wall removal that compromises cartridge consistency and firearm safety.

This pilot addresses a critical requirement in the handloading workflow: brass cases must be trimmed to specification to ensure proper seating, consistent powder charges, and reliable primer pocket integrity. Reloaders working with .308 Winchester, 7.62×51mm NATO, .300 Win Mag, or other cartridges in this caliber family rely on properly sized trimmer pilots to maintain batch uniformity. The Hornady Case Trimmer Pilot #10 is essential for shooters committed to precision ammunition manufacturing and long-term equipment reliability.
