In-Depth Review: RCBS Rock Chucker Supreme
The RCBS Rock Chucker Supreme is the workhorse. It’s the press you see on benches decades old. Its cast-iron “O” frame provides immense strength and rigidity, eliminating flex during tough operations like resizing large rifle brass.
Key Features & Performance
Let’s break down what makes it a perennial favorite.
- Construction: Massive cast-iron frame with a 4-inch opening. It handles any cartridge up to .50 BMG.
- Leverage: The compound linkage system provides exceptional mechanical advantage. Resizing stubborn brass feels smooth.
- Priming System: It includes a reliable on-press priming arm. Many users, however, prefer to hand prime for ultimate sensitivity.
- Versatility: The universal ram accepts all standard shell holders. It’s the centerpiece of a system you can build around for years.
This press excels in teaching reloading for beginners. Its operation is straightforward and incredibly strong. The feedback it provides is direct, helping you build proper technique from round one. It’s the definition of a best reloading press for building a lifelong skill.
In-Depth Review: RCBS Summit Press
The RCBS Summit Press takes a different, more modern approach. It’s a co-axial, inline design where the ram is guided by a large bronze bushing at the top of the press. This design aims for ultimate alignment and smooth operation.
Key Features & Performance
The Summit is all about finesse and precision.
- Construction: Cast-iron “C” frame with a unique inverted design. The ram pulls up into the die, which some find offers better visual access.
- Alignment: The co-axial design is legendary for promoting perfect die-to-case alignment. This is a key factor in consistent bullet seating for precision reloading.
- Priming System: It uses a superb off-press hand primer tool (included). This separation of operations is preferred by many precision shooters.
- Handle Feel: The action is notably smoother than a traditional “O” frame, with less perceived effort on the downstroke.
The big question for many is, is the RCBS Summit press worth the money? If your primary focus is precision rifle cartridges where consistent neck tension and bullet runout are critical, the answer is often yes. Its design philosophy is built for that task.
Head-to-Head Comparison & Key Differences
