Deciding on a reloading press often feels like choosing between a scalpel and a production line. Both are tools of immense capability, but their purpose defines their design. The RCBS Rock Chucker Supreme Press and the Dillon Precision RL550C represent two fundamentally different philosophies in the reloading world. One is the bedrock of meticulous craftsmanship, while the other is an engine for volume. Your goals at the reloading bench will determine which one is your perfect partner.
Honest OpinionThis isn’t just about picking a machine; it’s about aligning a tool with your shooting habits, your budget, and your patience for setup. Do you chase the absolute tightest groups on paper, or do you need to replenish a stockpile of practice ammo for the weekend? Honestly speaking, the right answer varies wildly from shooter to shooter. Let’s break down these two titans to find your match.
Head-to-Head: Rock Chucker Supreme vs. Dillon RL550C
At their core, these presses operate on different principles. The Rock Chucker is a classic single-stage press, handling one operation per cartridge in a single stroke. The Dillon RL550C is a manual-indexing progressive press, performing multiple operations (like sizing, priming, charging, and seating) with each pull of the handle as the shell plate rotates. This fundamental difference dictates everything about their use.

Detailed Analysis: Where Each Press Excels
For the Pursuit of Ultimate Precision
If your world revolves around sub-MOA groups and meticulous case preparation, the RCBS Rock Chucker is your anvil. Its massive, rigid frame eliminates flex, ensuring every stroke is identical. This is critical for operations like full-length resizing and bullet seating where thousandths of an inch matter. The process is slow, deliberate, and allows for inspection at every single stage. You handle each case individually, which fosters an intimate understanding of your components. For precision rifle reloading, this methodical approach is often considered non-negotiable. My honest assessment is that the Rock Chucker builds foundational skills that benefit any reloader, forever.
For High Volume Reloading and Efficiency
The Dillon RL550C shines when the goal is quantity without sacrificing reasonable quality. Its progressive design dramatically increases reloading speed. The case-activated powder measure is a game-changer for consistency and preventing mess. Manual indexing means you, the operator, control the rotation of the shell plate. This allows you to visually verify each station before proceeding, offering a great balance between speed and oversight. Changing calibers is streamlined with the removable toolhead system, making it fantastic for shooters who regularly switch between pistol and rifle. Honestly speaking, for someone burning through hundreds of rounds of 9mm or .223 a month, the time savings are immense.
Cost, Value, and the Intangibles
The upfront cost difference between Rock Chucker Supreme and Dillon 550C is significant. The Rock Chucker presents a lower barrier to entry. However, evaluating long-term value requires a broader lens.
- Initial Investment: The Rock Chucker is typically less expensive. You’ll need to add a scale, calipers, dies, and a priming tool. The Dillon is a larger initial outlay but often includes a robust primer system and powder measure in the package.
- Modularity & Future-Proofing: Dillon’s system is built for expansion. Conversion kits for new calibers are straightforward. The Rock Chucker is a fixed, supremely strong toolit does one thing perfectly but doesn’t “convert.”
- Warranty & Customer Service: This is a major differentiator. Dillon is legendary for its “no-BS” lifetime warranty and stellar support. RCBS also offers excellent support, but Dillon’s reputation in this area is a key part of its value proposition.
- Noise & Vibration: The solid, heavy construction of the Rock Chucker tends to dampen vibration and feel more solid on the bench. Progressive presses have more moving parts, which can transmit a different feel during operation.
So, is the Dillon 550C worth the extra money over the Rock Chucker? From my honest perspective, it is if your shooting volume justifies it. The investment pays for itself in time saved. If you’re loading 50 rounds a month for a hunting rifle, it’s likely overkill.

There is no universal “best” press. There’s only the best press for you. I honestly believe the RCBS Rock Chucker Supreme is the undisputed best press for beginners and the gold standard for precision-focused reloaders. It teaches patience and perfection. The Dillon RL550C is a productivity powerhouse for the active shooter who understands the process and needs to feed multiple firearms.
