The Hornady .17 Caliber Trimmer Pilot and Cutter (brand part no. 390942) is a caliber-specific replacement pilot and cutter set for Hornady’s case trimmer system. The pilot guides the cutter through the case mouth during trimming, keeping the cut square and centered so .17 caliber brass comes out consistently sized without deforming the case neck. It’s a small, inexpensive accessory, but it’s exactly the piece that determines whether your case trimmer produces clean, repeatable cuts on this caliber. Any .17 caliber handloader running a Hornady trimmer should keep a spare on the bench, since pilots and cutters do wear with use.
