The RCBS Rock Chucker Supreme is a single-stage reloading press built around one core principle: deliver the leverage and reliability you need to load ammunition safely and consistently, shift after shift. Whether you're setting up your first reloading bench or adding to an established operation, this heavy-duty press has earned its reputation as the workhorse that serious handloaders and rifle cartridge enthusiasts trust. Its central pivot design and long handle give you mechanical advantage where it counts—sizing stubborn brass and forming magnum cases without strain or risk of walking your press across the bench.
Built from cast iron and designed for ambidextrous operation, the Rock Chucker Supreme accepts standard 7/8"-14 thread dies with bushing and 1-1/4"-12 dies without bushing, so it integrates seamlessly with industry-standard tooling. The spacious 4.25-inch loading window accommodates longer magnum cartridges comfortably, and the large mounting footprint combined with reinforced anchor points means this press stays put under pressure. It's the kind of equipment that doesn't demand your attention—it just works, year after year.
RCBS backs the Rock Chucker Supreme with their legendary warranty and manufactures it in the USA. If you're serious about precision ammunition assembly and want a press that handles both common and magnum cartridges without compromise, this is the benchmark against which other single-stage presses are measured.
