The Hornady Case Trimmer Pilot #20 (part no. 390962) is sized to .361 inch and drops into either the Hornady Cam-Lock Case Trimmer or the original Hornady Case Trimmer to guide the cutter squarely down the case mouth. Hornady builds each pilot from quality materials specifically because a loose or undersized pilot is how reloaders end up with a crooked, uneven trim. This is a small, inexpensive part, but it’s the difference between a case that trims true and one that doesn’t.
