RCBS Rock Chucker Supreme Press Best Overall
- Frame
- Cast-iron O-frame
- Weight
- 20 lb
- Die Threading
- Standard 7/8"-14
- Loading Window
- 4.25 inches
The 4.25-inch loading window is the first thing we notice, and it is the reason this press is easy to live with. Long rifle cases sit in the shell holder with enough room to guide a bullet without scraping your knuckles, and the open front makes it simple to see what the case is doing. The cast-iron O-frame adds the other half of the story: when you full-length size a stiff piece of brass, the press stays planted instead of flexing.
We like the standard 7/8"-14 threading because it takes the dies most reloaders already own, and the long handle gives plenty of leverage for resizing. The spent-primer catch is a small detail that matters more after a hundred rounds, and it keeps the bench cleaner than an open ram slot. The press is a bench fixture in the best sense, built to be bolted down and left alone.
The one thing we watch is the linkage. If a case sticks, stop and fix the cause rather than forcing the handle through cam-over; that is the kind of load that can break parts. Otherwise, the Rock Chucker Supreme is the press we reach for when we want one deliberate operation at a time and no drama. It is also the foundation of the Master Kit, which is the route we recommend for a first bench.
What We Like
- Generous 4.25-inch loading window
- Cast-iron O-frame stays planted
- Standard 7/8"-14 die threading
- Lifetime warranty backs the press
Worth Noting
- Heavy 20-pound bench presence
We recommend the Rock Chucker Supreme as the default single-stage press for reloaders who want a stable, precise bench press with room for long rifle cases.
