Two names dominate the conversation for a first serious reloading press: the Lee Precision Anniversary Challenger Kit II and the RCBS 9356 Rock Chucker Supreme Press. One arrives as a complete kit, promising an immediate start. The other is a legendary, press-only unit built for a lifetime of heavy-duty use. This isn’t just about tools; it’s about two fundamentally different philosophies for entering the world of precision reloading.
For a beginner, the choice can feel overwhelming. Do you prioritize upfront value and a complete setup, or invest in a heirloom-quality foundation? My honest assessment is that both are excellent, but they serve different masters. Let’s break down exactly what you get, how they perform, and which path makes the most sense for your bench.
Head-to-Head: Lee Challenger Kit II vs RCBS Rock Chucker Supreme
Seeing the core specifications side-by-side reveals their distinct identities immediately. The Lee is a system, while the RCBS is a component.

Build Quality & Durability: Cast Iron vs. A Legacy
Both presses utilize a robust O-frame design and cast iron construction. This is where similarities in the feel end. The RCBS Rock Chucker Supreme’s description emphasizes its heavy-duty engineering: a full four inches of ram-bearing surface rigidly supports a massive one-inch diameter main ram. The handle is solid steel. This speaks to a press designed for immense leverage and minimal flex, even under heavy resizing operations. Its built like a piece of industrial machinery.
The Lee Challenger is also cast iron and perfectly capable for most calibers. Honestly speaking, the difference isn’t about one breaking and the other not. It’s about mass, rigidity, and the smoothness that comes from over-engineering. The RCBS simply has more of it. Its legendary status is backed by that unbeatable Lifetime Warranty. For long-term durability and peace of mind, the Rock Chucker sets a high bar.
Performance: Precision & Ease of Use
Precision in a single stage press comes from consistency. A rigid frame that doesn’t flex and a smooth, predictable handle stroke are key. The RCBS, with its compound leverage system and massive ram, provides an exceptionally smooth and powerful operation. This consistency translates directly to uniform ammunition.
The Lee Challenger provides a very good mechanical advantage for its price. Where the Lee kit truly shines for reloading for beginners is in its included workflow tools. The “very sensitive” Lee Safety Scale is a legitimate tool for learning precise powder measurement. The chamfer tool and power funnel eliminate the need for immediate additional purchases. You can literally unbox the kit and start learning the process of precision reloading. The RCBS requires you to source each component separately, which is an advantage for customization but a hurdle for a first-timer.
A critical, often overlooked entity is the Primer Catcher System. Speaking honestly, the efficiency and containment of spent primers is a major quality-of-life factor. While not detailed in the core features, the design of these systems differs and is worth researching as you consider your bench cleanliness.
Value Proposition: Kit Contents vs. Press-Only Cost
This is the heart of the debate. The Lee Challenger Kit II is arguably the best value entry point in all of reloading. For one price, you get a functional press, a scale, a funnel, and a case prep tool. You can begin learning immediately. My honest take is that for someone unsure if reloading is for them, this is the lowest-risk, highest-reward path.
The RCBS Rock Chucker Supreme is a press-only purchase. Its price is often close to the entire Lee kit. However, you are investing in a tool that will never need upgrading. You then build your perfect system around itchoosing your preferred scale, powder measure, and case prep tools from brands like Hornady or Lyman. This path costs more upfront but results in a superior, customized setup. It’s the choice for the committed enthusiast.
Consider reloading kit accessories and their long-term cost. A good scale alone can cost a significant fraction of the Lee kit. Honestly, if you see yourself reloading for years, buying the RCBS and adding quality components piecemeal is the wiser financial move over a decade.
Covering the Nuances: Caliber, Maintenance, and Parts
Most reloading press reviews miss key practical details. Both presses handle a wide range of rifle and pistol calibers with standard dies. However, for massive magnum cartridges, the RCBS’s superior rigidity may offer a tangible advantage in smoothness.
Maintenance is simple for botha periodic wipe-down and a drop of oil on the ram. The real difference lies in the availability of replacement parts. RCBS, with its lifetime warranty and massive support, excels here. Lee Precision also has good support, but the ecosystem for aftermarket upgrades and accessories, like from Inline Fabrication, is more extensive for the Rock Chucker due to its iconic status.
Final Verdict & Recommendation
So, which wins this reloading press comparison? It depends entirely on your profile.
Choose the Lee Precision Challenger Kit II if:
- You are a total beginner and want the simplest, most cost-effective all-in-one start.
- Your budget is tight and you need to begin reloading now with minimal extra purchases.
- You’re loading standard rifle and pistol calibers without extreme pressures.
- You value the immediate utility of included tools like the scale and chamfer tool.
Choose the RCBS Rock Chucker Supreme Press if:
- You are committed to reloading long-term and view your press as a lifetime investment.
- You demand maximum rigidity and smooth operation for precision rifle reloading.
- You prefer to hand-select each component (scale, powder measure) for your perfect workflow.
- The strength of a no-questions-asked Lifetime Warranty is a decisive factor for you.
From my honest perspective, there is no single best reloading press for everyone. The Lee Challenger Kit II is the ultimate gateway drug. It gets you hooked on the craft with minimal friction. Many reloaders start with it, then later upgrade the press while still using the included accessories. The RCBS Rock Chucker Supreme is the press you buy once. It is the unwavering foundation of a serious reloading bench.
For the absolute beginner on a strict budget, the Lee kit is the smarter first step. For the shooter who knows they’re in it for the long haul and can allocate a larger initial budget, the RCBS is the unequivocal choice. Regardless of your path, the journey toward making your own ammunition is incredibly rewarding. Remember, the best press is the one you’ll use consistently to safely produce quality rounds.
