ABSTRACT:
A controlled depth primer seating tool and method for use thereof in firearm cartridge loading and reloading operations, which enables the accurate measured depth of seating of a primer within the primer pocket of a center fire cartridge case by accommodating both cartridge case plus primer variations so that the measured depth of primer seating provides for a slight pre-load compression of the anvil head of the primer against the explosive compound contained therein whereby firing pin impact energy is thus optimally expended in effecting consistency of primer ignition with a corresponding enhancement of consistent ballistic characteristics from cartridge-to-cartridge and consequent accuracy from round-to-round.
