Abstract
A controlled depth cartridge case chamfering tool and method for use thereof in firearm cartridge loading and reloading operations, which enables the adjustably set repeatedly uniform taper chamfering of the mouth interior of a sized and trimmed cartridge case to provide a consistently uniform radially aligned and squarely disposed truncated conically shaped gradual taper therewithin and thereby allow for a greater ease of insertion and smoothness of seating of a bullet tip during loading or reloading operations without the otherwise inherent hazard of heel and base marring or damage thereto.
Claims8
A controlled depth cartridge case chamfering tool for accomplishing adjustably set repeatedly uniform taper chamfering of the mouth interior of a sized and trimmed cartridge case to provide a consistently unifrom radially aligned and squarely disposed truncated conically shaped gradual taper therewithin respectively from case-to-case within a run lot and thereby facilitate bullet tip placement and seating in accomplishing cartridge loading or reloading operations, comprising:
- (a) an elongated handle provided with a reamer shaft receiving opening;
- (b) a reaming cutter tool having integral thereto a chucking shaft adapted to be slidably supported within said reamer shaft receiving opening;
- (c) a means in said handle to lockably secure said chucking shaft at a variably set adjusted position within said elongated handle;
- and
- (d) a plurality of radially spaced reaming cutter tool depth stop guides extending from the base of said elongated handle cooperatively with said reaming cutter tool and adapted to adjustably limit the depth of case mouth interior depth of chamfering cut thereof.
