Redding Big Boss Ii Reloading Press

The Redding Big Boss II reloading press is a heavy-duty cast iron single-stage press built for serious reloaders who want one rock-solid machine to handle everything from small handgun rounds to magnum rifle cartridges. With the largest frame opening and ram stroke in its class, the Big Boss II gives you the reach and leverage you need for consistent, reliable case processing without cramping your workspace or your technique.

The 36° offset O-frame design opens up a full 4½ inches of height, so you're not hunting for room to seat bullets or deal with awkward angles when loading magnum cases. That generous opening, combined with the offset ball handle, makes the press smooth and effortless to operate—you get real mechanical advantage on every stroke without white-knuckling it. Whether you're running through a thousand rounds of .308 or loading match-grade .338 Lapua, the Big Boss II won't fight you.

The press accepts standard 7⁄8"-14 dies out of the box, and Redding has built in flexibility: you can swap in a 1"-14 bushing (sold separately) or remove the bushing entirely to run 1¼"-12 dies. That means you're not locked into one die system as your reloading evolves. The spent primer collection system is the same proven design found on Redding's turret and UltraMag presses—primers automatically drop through the 1" diameter ram and feed down into a flexible plastic tube that holds hundreds of primers, making disposal clean and hassle-free.

Frequently Asked Questions

Can the Big Boss II handle magnum rifle cartridges?

Yes. The Big Boss II is designed to work with all rifle and handgun cartridges, from small rounds to the largest magnum cases. Its large frame opening and generous ram stroke give you the clearance and power needed for magnum reloading.

What dies are compatible with this press?

The press comes set up for standard 7⁄8"-14 dies. You can purchase a separate 1"-14 bushing to use those dies instead, or remove the bushing entirely to run 1¼"-12 dies. This flexibility lets you adapt to different die systems as needed.

Primers automatically drop through the 1" diameter ram and feed down into a flexible plastic tube that attaches below. The tube holds hundreds of primers and makes disposal clean and convenient—no loose primers rolling around your reloading bench.
