Forster Case Trimmer Pilot #20

The Forster Case Trimmer Pilot #20 is a precision reloading component designed for use with Forster's Original Classic and Power case trimmers. This small but essential pilot serves a critical function in the case preparation stage of ammunition reloading—ensuring that trimmed brass maintains the correct neck diameter for consistent bullet seating and cartridge performance.

The #20 pilot is sized for specific calibers and requires precise matching to achieve optimal results during the case trimming process. Selecting the correct Forster case trimmer pilot diameter is imperative for reloading success. The pilot must be slightly smaller than the inside neck diameter of the brass after full-length sizing—a specification that directly affects how securely the bullet seats in the case neck.

Reloaders building match-grade ammunition will benefit most from using the correct pilot, as it ensures uniform case neck dimensions and repeatable cartridge assembly. Verifying compatibility with your particular caliber and brass lot before purchase is essential. Forster Products manufactures these pilots to tight tolerances, ensuring reliable performance across multiple reloading sessions.
