Hornady's Cam Lock Trimmer is the only trimmer within this price range that features a micro-adjustable cutting head. The unique way the case is locked in place in the shell holder ensures that all trim lengths are accurately measured from the base of the cartridge, with no variation due to rim thickness. The Cam Lock Trimmer includes the seven most popular pilots: .22 cal., 6mm, .270 cal., 7mm, .30 , .38 cal., and .45 cal. A light touch of the knob locks the case in place, holding it square with the cutter for precision trimming; another touch releases it. The large cutter trims cases up to .50 caliber in diameter, is easily removed for resharpening or replacement, and is made of ultra-hard, super-sharpened tool steel that keeps its edge practically forever.
