The Hornady Cam-Lock Case Trimmer Pilot for .303/7.7 mm (.311-.312) (Hornady part no. 390952) is a caliber-specific pilot built for the Hornady Cam-Lock Case Trimmer. It centers and guides .303/7.7 mm (.311-.312) brass through the trimmer’s cutter head so the case mouth comes out square and consistent for reloading. Machined from steel, this pilot is interchangeable with every other pilot in the Hornady Cam-Lock Trimmer lineup, letting a single trimmer body cover multiple cartridges. Serious handloaders working up .303/7.7 mm (.311-.312) brass rely on a correctly sized pilot from Hornady to keep trim length consistent across a batch of cases.
