RCBS Rock Chucker Supreme Press – Single Stage Reloading Press

The RCBS Rock Chucker Supreme is a cast iron single-stage reloading press built for precision ammunition assembly across all standard rifle and pistol cartridges. This O-frame press handles full-length resizing, bullet seating, and crimping operations with consistent leverage and alignment for shooters who prioritize accuracy over speed.

The press features a 1-inch ram with 4.125 inches of stroke, providing clearance for magnum-length cartridges up to .416 Rigby. Its offset handle design increases leverage during heavy resizing operations, and the ambidextrous primer arm accommodates both large and small primers. The compound leverage system and solid cast iron construction minimize frame deflection during high-pressure sizing tasks. Compatible with all standard 7/8"-14 threaded dies.
