Abstract

A case trimmer and chamfer tool preferably includes a trim die, an end cutter, a crank, an outer chamfer blade, an inner chamfer blade and a height adjustment ring. The end cutter is slidably retained in the trim die. The inner and outer chamfer blades are spring loaded. The end cutter trims a length of the cartridge case. The inner and outer wall of the cartridge case are chamfered by the inner and outer chamfer blades. An adjustment boss extends downward from one end of the crank and a rotating knob is retained on the other end thereof. The end cutter is retained in the adjustment boss. The height adjustment ring is retained on the adjustment boss. A second embodiment is adapted for handling straight cartridge cases instead of rifle cartridge cases. The case trimmer and chamfer tool and a cartridge case are retained in a loading press.
