Deciding on your first reloading setup can feel overwhelming. You’re faced with a fundamental choice: invest in a comprehensive kit or start with a focused, high-value component. Two names dominate this conversation for the 9mm Luger enthusiast: the Lee Precision 92134 Challenger 40th Anniversary Pack and the RCBS Rock Chucker Supreme Master Reloading Kit. One offers a streamlined path with a press and dies, while the other provides an almost complete workshop in a single box.
This isn’t just about picking a product; it’s about selecting your reloading philosophy. Do you prioritize an all-in-one solution from a legendary brand, or do you favor a modular, cost-effective entry point with renowned dies? Speaking honestly, both paths are valid, but they lead to very different initial experiences and long-term bench setups. Let’s break down what each product actually delivers.
Head-to-Head: The Core Proposition
At their heart, these are two different product categories. The Lee Precision 92134 is a press-and-die bundle specifically for 9mm. The RCBS kit is a full-fledged starter system missing only dies and shell holders. Understanding this core distinction is crucial before we dive into the specs.

Detailed Feature Breakdown & Comparison
Now, let’s examine the components that define your reloading workflow. From the single stage press itself to the critical tools for case sizing and bullet seating, the differences become stark.
The Press: Strength vs. Refinement
Both presses utilize the robust O-frame press design. The Lee Challenger is noted for its strength and popularity, with a 4-inch opening for hand clearance. The RCBS Rock Chucker Supreme, the benchmark in its class, features a slightly larger 4.25-inch window and a central pivot design engineered for exceptional leverage on tough cases. Honestly speaking, both are more than capable for 9mm Luger, but the Rock Chucker’s reputation for enduring precision is well-earned.
The Dies: Lee’s Famous Carbide vs. RCBS’s Absence
This is the most significant differentiator. The Lee bundle includes its 9mm Luger Breech Lock 3-Die Set. The key here is the carbide sizing die, which eliminates the need for case lube on straight-walled pistol casesa massive convenience boost for beginners. The Breech Lock system allows for instant die changes. The RCBS kit, conversely, includes no dies at all. You must purchase a 9mm die set separately, which from my honest perspective, is a critical upfront cost to factor in.
Kit Completeness: Ready to Load vs. Ready to Build
The RCBS kit’s value is in its breadth. It surrounds its legendary press with professional-grade components:
- Uniflow-III Powder Measure: Praised for consistent, accurate charges.
- M500 Mechanical Scale: A magnetic-damped beam scale for precise weighing.
- Hand Priming Tool, Case Lube Kit, Debur Tool, Loading Block, Funnel, and Speer Manual.
The Lee pack gives you a press and excellent dies. You’ll need to source a scale, powder measure, case prep tools, and a manual separately. My honest take is that the RCBS kit gets you operational faster, while the Lee route requires more initial research and piecemeal purchasing.
Performance Analysis: Accuracy & Ease of Use
How do these choices translate to the bench? Reloading accuracy for 9mm on a single stage press hinges on consistency and technique.
Workflow and Consistency
The RCBS Uniflow-III powder measure and M500 scale are a proven combo for charge consistency, directly impacting accuracy. The separate hand priming tool allows for sensitive, tactile feedback on primer pocket seating. The Lee setup relies on you choosing compatible, quality components for these steps. For the actual bullet seating and crimp die operation, both presses offer precise control. The RCBS press might have a slight edge in smoothness and feel, but the Lee’s Breech Lock system makes die adjustment and changes incredibly fast.
The Beginner Experience
If you want my honest opinion, a true beginner might find the all-in-one nature of the RCBS Rock Chucker kit components less daunting. Everything is matched and designed to work together, including a vital reloading manual. The Lee path is fantastic for the budget-conscious learner who doesn’t mind sourcing other tools, perhaps opting for a digital scale or a different powder measure. The included carbide sizing die is a huge win for simplicity.
Value Proposition & Total Cost Analysis
The sticker price is only part of the story. You must consider the total cost to produce your first round.
Initial Investment & Hidden Costs
The Lee Precision 92134 pack has a lower entry price. However, you must immediately budget for:
- A precision scale (beam or digital).
- A powder measure or trickler.
- Case prep tools (though a debur tool is often included with die sets).
- A reloading manual (non-negotiable for safety).
- Case lube if you ever load rifle cartridges.
The RCBS kit’s higher price includes all these essentials except the dies. The cost of upgrading RCBS Rock Chucker kit with Lee dies is a popular and savvy hybrid approach. You get the superb RCBS press and tools paired with Lee’s cost-effective, user-friendly carbide dies. It’s a compelling middle ground.
Long-Term Value and Flexibility
The RCBS kit is an investment in a system. The press, scale, and powder measure are pieces you’ll likely never need to upgrade. The Lee Challenger press is a solid performer, but some reloaders eventually upgrade the press while keeping the excellent Breech Lock dies. Thinking about a progressive press alternative down the line? The RCBS scale and powder measure will still be invaluable on your bench, while the Rock Chucker becomes your dedicated single stage press for precision rifle or processing tasks.
Final Verdict & Recommendation Scenarios
So, which is better for beginner reloading Lee dies or RCBS kit? It depends entirely on your profile and goals.
Choose the RCBS Rock Chucker Supreme Master Kit if:
- You want a true “one-box” start with minimal supplemental shopping.
- You value top-tier tools and don’t mind a higher initial investment.
- You plan to reload multiple calibers, especially rifle, and want a forever press.
- You prefer the methodical, tool-by-tool process of a traditional hand priming tool and separate powder measure.

Choose the Lee Precision 92134 Challenger Pack if:
- Your budget is the primary constraint and you need to spread costs over time.
- You are 100% focused on 9mm Luger for the foreseeable future.
- You enjoy researching and selecting individual components (scale, measure, etc.) to customize your kit.
- The convenience of a carbide sizing die and quick-change Breech Lock system strongly appeals to you.
The Hybrid Champion Approach
My honest assessment is that for many new reloaders, the optimal 2026 solution is a hybrid. Purchase the RCBS Rock Chucker Master Kit for its unparalleled foundation, then add the Lee Precision 9mm Carbide 3-Die Set. You bypass the need for case lube on pistol rounds and gain the Breech Lock convenience, all while building your bench around legendary RCBS durability. This combo arguably creates the best 9mm reloading setup for a serious beginner.
Regardless of your choice, remember that precision reloading requires verification. Investing in a case gauge or headspace gauge to check your finished 9mm rounds is non-negotiable for safety and reliability. Always consult multiple official sources for load data, including manuals from rcbs, Lee, and others like Hornady.
In the end, both products deliver exceptional value in their own lane. The RCBS kit is the comprehensive workshop. The Lee pack is the efficient, focused entry ticket. Your decision hinges on whether you want to build a bench immediately or assemble one deliberately.

From my Honest Opinion, you can’t go wrong with either as a starting point for the rewarding craft of reloading.
