Redding Big Boss Press

Redding Big Boss Press

The Redding Big Boss is a heavy cast iron single stage press built for reloaders who size and form long magnum rifle cases and want more room and ram travel than a standard press gives them. It has the same frame as the Big Boss II: a 1" diameter ram, 3-13/16" of usable ram stroke and a 4-1/2" frame opening, so you can run belted and long-action magnums, and large-diameter cases like the .338 Lapua, without fighting the press for clearance. The 36° frame offset keeps the case mouth in view and gives your hands room to work.

Standard 7/8"-14 dies thread into the included steel adapter bushing. Remove the bushing and the frame accepts 1-1/4"-12 dies, so the press is ready for Redding's 1" Z Series dies and other large-body dies without an adapter.

Priming is done on the press with the Smart Primer Arm, which swings into position during the ram stroke and flips out of the way when you are not using it; priming happens at the end of the stroke where leverage is lowest and feel is best. Both large and small primer arm assemblies are included.

Big Boss vs. Big Boss II

The difference is spent primer handling. The original Big Boss (this press, Redding #79000) uses a conventional Boss-style primer catcher mounted at the ram. The Big Boss II routes spent primers down through a hollow ram into a flexible tube. If you want the tube system, choose the Big Boss II; otherwise this press gives you the same frame, ram and stroke at a lower price.
