The Forster Co-Ax® Loading Press comes with several unique features that help make it truly one of a kind, including: snap-in and snap-out die changing, a positive spent primer catcher system, and dual floating guide rods to help ensure perfect alignment. The Co-Ax® Press has three times the mechanical advantage of an ordinary "C" press resulting in effortless, full length sizing. The Co-Ax® Press delivers perfect alignment of the die and the case because the shell holder jaws are designed to float with the die, thereby permitting the case to center precisely in the die. Accepts any standard 7/8" X 14 reloading die, some with existing locking rings. Includes “S” jaws to fit most calibers. “LS” jaws sold separately.
