The Hornady 8mm (.323) Cam-Lock Case Trimmer Pilot (Hornady part no. 390953) fits inside a Hornady Cam-Lock case trimmer’s cutting head to center a 8mm (.323) case by its neck for a square, consistent trim. Made by Hornady, this pilot is sized to the caliber’s neck inside diameter, keeping the case aligned on-axis so the trimmer cuts the case mouth square instead of at an angle. Handloaders trimming rifle brass to a uniform length rely on the correct pilot size for consistent case-to-case trim length and a square case mouth that seats bullets cleanly. It’s an inexpensive accessory that has an outsized effect on trim quality.
