This unique single stage press features: Snap in and snap out die changing. A positive spent primer catching system that passes all spent primers into a container for easy disposal and clean press/work area. Dual floating guide rods ensure perfect alignment. A unique top mounted priming device consistently seats primers to factory specifications. The design of the press provides for three times the mechanical advantage of an ordinary "C" press and easy operation for right or left handed reloaders. Utilizes unique shellholder jaws design that does not require "standard" shellholders. The shellholder jaws "float" to permit the cartridge to find the exact center of the die. Jaws are self-actuating and open and close with the movement of the press handle. Standard jaws are included that fit the majority of calibers. Optional "LS" Jaws are available (see list of calibers below). Optional Shellholder Adapter plate allows loaders to use standard shellholders in place of the jaws. Co-Ax Press accepts standard 7/8"x14 dies.
