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.
