The Hornady Cam Lock Trimmer is specially designed with a micro-adjustable cutter that makes it possible to modify length in increments of 0.001 inches and without the case being moved. The trimmer boasts a one-finger cam-lock that keeps the case securely in place with a single touch. Then with a second touch, the case is released. For larger diameter cases, cutting heads can trim up to .50 caliber while leaving a tall frame to prevent hands hitting the reloading bench. This trimmer has a base that measures 8x2.5 inches and four holes for mounting. Pilots Included: 22 Caliber, 6mm, 270 Caliber, 7mm, 30 Caliber, 38 Caliber and 45 Caliber
