The RCBS Rock Chucker Supreme Press with Auto Priming Unit transforms your single-stage reloading workflow by automating one of the most repetitive and time-consuming steps at the bench. If you're loading volume and tired of hand-priming one round at a time, this tube-fed priming system mounts directly to your Rock Chucker Supreme and handles the job faster and with less fatigue. The auto priming unit holds up to 100 primers in its tube feed, so you can focus on case prep, powder charging, and bullet seating while primer seating becomes a simple push-pull operation.
What sets this upgrade apart is the straight push-pull motion of the primer arm slide—a design that reduces the frustration of primers popping out of the seat plug mid-stroke. The included safety shield adds peace of mind when working with a full primer tube, and you get both large and small primer pick-up feed tubes and matching seat plugs right out of the box, so you're ready to run whatever primer size your loads call for. Reloaders who shoot multiple calibers or load in volume will feel the time savings immediately.
The auto priming unit attaches to the same location as the standard priming arm, making installation straightforward on any Rock Chucker Supreme. Load faster, handle primers less, and keep your focus on consistency and accuracy where it matters.
