The RCBS Rock Chucker Supreme sets the standard by which other single-stage presses are judged, delivering straightforward operation, an ambidextrous handle, exceptional strength, and broad capability. A cast iron frame delivers dependable performance and resists flex during reloading, while the generous 4.25″ loading window accommodates longer magnum cartridges. Oversized mounting points and an extended handle make case sizing manageable and keep the press secure on your bench.
The central pivot design offers strong mechanical advantage for sizing demanding cases, performing equally well for rifle and shotshell work. The ambidextrous handle installs for either right or left-hand operation to suit both right- and left-handed users. An integrated spent primer collection system maintains a clean work area, and the press accepts standard 7/8″-14 thread dies with bushing and 1-1/4″-12 without bushing.
For over a decade, the Rock Chucker Supreme has earned its reputation for versatility and robustness as the preferred choice for new and seasoned reloaders alike. From your first handload to your thousandth round, this single-stage press delivers the precision and durability serious handloaders demand.
