- Frame

- Weight
- 20 lb
- Press Type
- Single stage
- Loading Window
- 4.25 inches
Cast iron is the reason to buy this press, and 20 pounds of it is the reason it stays where you bolted it. The Rock Chucker Supreme has a 4.25-inch loading window, which reads like a spec until you're lowering a long magnum case into the shell holder with cold hands — then it's the difference between a rhythm and a fiddle. We like the long handle for the same reason: full-length sizing on belted brass takes real leverage, and this press has leverage to spare.
The work it's really for is the ammunition you care most about. Single-stage loading is one operation at a time — size every case, then prime every case, then charge and seat — and the slowness is the point: every round gets the same stroke, the same feel, the same seating depth. For match rifle, hunting loads, and anything where you're bumping a shoulder or working up a charge, that consistency is worth more than the rounds per hour you give up.
It's also the least fussy press here. Standard 7/8"-14 threads take the dies you already own, spent primers drop into a catcher instead of scattering across the bench, and the cast iron doesn't care whether you're running .223 or .45-70. RCBS backs the whole thing with a lifetime warranty.
Where it stops making sense is high-volume pistol. Four strokes a round adds up fast, and if a weekend's shooting is a few hundred 9mm rounds, the Lee turret below is the better buy. The Rock Chucker earns its bench on the rifle cartridges you'd otherwise be weighing every charge for.
What We Like
- Cast-iron frame and 20-pound weight stay put under sizing
- 4.25-inch opening clears long magnum cases
- Standard 7/8"-14 threads fit common dies
- Lifetime warranty
Worth Noting
- Linkage arms can fail under heavy case-forming
Our default recommendation: a cast-iron single stage with the leverage for magnum brass and the consistency for match loads, built to outlast the bench it sits on.
