The RCBS Rockchucker Supreme Auto-Prime (RCBS part no. 9358) converts the Rockchucker Supreme from one-at-a-time hand priming to a fast, tube-fed system that eliminates direct handling of primers. A 100-primer capacity feed tube keeps the press running through long sessions without constant reloading, and a simple push-bar operation seats each primer with consistent pressure. Because the whole system feeds primers through a tube rather than placing them by hand, it dramatically increases the speed of single-stage reloading while also reducing the chance of a primer detonating from mishandling. Built by RCBS specifically for the Rockchucker Supreme press, this attachment includes large and small primer pickup tubes, feed tubes, and primer seat plugs, plus a safety shield for protection during operation.
