Forster Products Inc 028271 Co-Ax Press with (S) Jaws
The Forster Products Co-Ax reloading press with standard jaws is a single-stage press built for handloaders who want precision without unnecessary complexity. Whether you're developing ammunition for hunting, target shooting, or match competition, the Co-Ax's centered design and mechanical advantage make it a workhorse that rewards attention to technique. The press is ambidextrous, which means lefties and righties both get a natural, unobstructed working position—no swinging primer arms or frame supports getting in your way.
What sets the Forster Co-Ax apart is how it handles die changes and spent primers. Snap-in, snap-out dies let you swap from sizer to seater in roughly two seconds, keeping your reloading session flowing without fumbling. The positive spent primer catcher system routes primers and carbon debris down a tube into a catch container, keeping your press clean and the working parts free of the abrasive buildup that degrades reliability over time. Dual floating guide rods maintain perfect alignment throughout the stroke, and the shell holder jaws float with the die itself to ensure the case sits exactly where it needs to be.
The Co-Ax delivers three times the mechanical advantage of a standard C-frame press, which means less effort per stroke and more control over sensitive operations like primer seating. The included top priming device seats primers straight, reducing the learning curve for consistent, safe primer insertion. The standard jaws accommodate two rim-diameter ranges: .343″ to .422″ and .468″ to .562″, covering most rifle and magnum cases you'll encounter.
This is a no-frills, high-precision tool for reloaders who understand that boring and reliable beats flashy and complicated. If you're building your own ammo and you want a press that handles the basics with quiet authority, the Forster Co-Ax earns its place on the bench.
