Two names dominate the conversation when you’re looking for a serious single stage press. The Lee Precision 90045 and the RCBS Rock Chucker Supreme Master Reloading Kit represent two distinct philosophies in the reloading world. One is a bare-bones, focused tool, while the other is a comprehensive system designed to get you started immediately. The choice between them isn’t just about a press; it’s about your entire approach to the bench.
Honestly speaking, this comparison cuts to the core of what you value most: pure component cost or a ready-to-run experience. Both have earned their reputations, but they serve different masters. Let’s break down exactly what each product offers, using only their stated features, to see which one aligns with your reloading journey.
Head-to-Head Comparison: Lee Precision 90045 vs RCBS Rock Chucker Supreme
At first glance, this seems like an apples-to-oranges comparison. And in many ways, it is. The Lee 90045 is a standalone press. The RCBS offering is a complete kit. This fundamental difference shapes every aspect of their value proposition. To be completely honest, you’re not just comparing two presses; you’re comparing a single component against an entire workstation.

Detailed Feature Breakdown & Specifications
Diving deeper, the nuances of each product become clear. The provided features tell a specific story about intended use and engineering priorities.
The Lee Precision 90045: The Bare Bones Workhorse
The Lee 90045 is described simply as a “Reloading Press.” From my honest perspective, this is its greatest strength and its most significant limitation. It makes no promises about included extras. You get a robust, cast-iron single stage press known for its simplicity and direct operation. It’s a blank canvas. This approach is perfect for the reloader who either:
- Already owns a scale, powder measure, and other reloading accessories.
- Wants to meticulously select each component of their setup, perhaps mixing brands like a Hornady measure with a Lyman manual.
- Is on an extremely tight budget and needs to acquire tools piecemeal over time.
The press itself is a proven design. However, you must immediately factor in the additional cost and research required for all the supporting gear not included.
The RCBS Rock Chucker Supreme Master Kit: The Turn-Key Solution
RCBS doesn’t just sell you a press; they sell you a system. The kit’s description is rich with detail, highlighting why it’s often called the “king of reloading kits.” The backbone is the legendary Rock Chucker Supreme press. Its compound leverage and central pivot design are specifically mentioned for handling tough case sizing with outstanding leverage. The 4.25″ window is a clear nod toward versatility for rifle cartridges, addressing specific caliber reloading performance for longer rounds.
Beyond the press, the kit is packed with purpose-selected components:
- Uniflow-III Powder Measure: Touted as the most accurate Uniflow ever, with tight tolerances for consistent charges.
- M500 Mechanical Scale: A magnetic-damped, two-poise scale for precise measurements up to 505 grains.
- Hand Priming Tool & Case Lube Kit: Essential tools for two critical stages of the process.
- Speer Reloading Manual: An invaluable resource, especially for a beginner reloader.
My honest take is that this kit is engineered to eliminate guesswork. Every major component you need to start loading safe, accurate ammunition (except dies and shell holders) is in one box, designed to work together seamlessly.
Target User & Use Case Analysis
This is where the “which is better for a beginner Lee or RCBS” question gets answered. The target user for each product is almost diametrically opposed.
The Ideal Lee 90045 User: This is the experienced reloader adding a dedicated press for a specific task, or the incredibly budget-conscious and patient beginner. They are comfortable sourcing components separately, comparing scales and measures, and potentially dealing with a more fragmented setup. They value the low initial entry cost above all else, accepting that the total system cost will be higher and assembled over time. For precision reloading where every component is scrutinized, this path allows for ultimate customization.
The Ideal RCBS Kit User: This is the classic beginner reloader or any shooter who values convenience and confidence. They want to buy one kit, set it on their bench (mindful of bench mounting requirements for a heavy press), and start learning with quality, matched tools. The included Speer manual is a critical safety and education tool. The value proposition here is time, simplicity, and the assurance that you have a complete, pro-grade system from a trusted brand like RCBS. The question of “best value single stage reloading kit” often points here, as the sum of the parts typically exceeds the kit’s cost.
Value Proposition & Total Cost of Ownership
Speaking honestly, the sticker price is a trap. You must think in terms of total cost to get to your first loaded round.
The Lee 90045 has a low initial cost. But then you must add:
- A precision scale (like the RCBS M500, which costs over $100 alone).
- A powder measure.
- A priming tool.
- Case lubrication method.
- Case blocks, funnel, deburring tool.
- A reloading manual.
Suddenly, the “budget” press is the core of a $500+ system you assembled yourself. The advantage? You could choose a digital scale, a different brand measure, or a specific hand primer you prefer.
The RCBS Rock Chucker Supreme Master Kit has a higher initial price. But it includes every single item on that list except the reloading dies. The M500 scale and Uniflow-III measure are high-quality staples. The hand priming tool is excellent. You are, in effect, getting a significant discount on a curated collection of tools. For a detailed look at the press itself, our rcbs press review dives deeper. The total cost of ownership from purchase to first cartridge is essentially the kit price plus dies.
Addressing Durability, Performance, and the
Questions about “Lee 90045 vs Rock Chucker Supreme durability” are common. The RCBS description explicitly markets its “outstanding strength” and legacy status. The Lee press is built from sturdy cast iron but its listing makes no specific durability claims. In my honest opinion, both are capable of lasting a lifetime for a hobbyist. The RCBS’s compound linkage may provide a mechanical advantage in perceived smoothness, especially on large rifle cases.
Competitors often miss a few practical considerations. Noise and vibration comparison can be a factor; a heavier, more massive press like the Rock Chucker may dampen more sound and shock. Both require solid bench mounting, but the RCBS kit’s total weight is considerably more, demanding a sturdier bench. The RCBS press includes a Primer Catcher System as a standard feature, a small but critical accessory for keeping your bench clean. The Lee may or may not include one; it’s not mentioned.
For those focused on reloading press comparison for precision rifle, the RCBS kit’s included mechanical scale is a trusted tool for charge weight consistency. The Lee path would allow you to invest that “saved” money into a high-end digital scale immediately. It’s a trade-off between a complete good system and an incomplete great one.
Final Verdict & Recommendation
So, which one wins? My honest assessment is that there is no single winner, only the right tool for the right person.
Choose the Lee Precision 90045 Reloading Press if:
- You already own the essential reloading accessories.
- You are a tinkerer who wants to build a custom bench piece-by-piece.
- The absolute minimum upfront cost is your primary, non-negotiable driver.
- You are replacing a press and need just the press.
You accept the research time and additional purchases required. For a broader look at the ecosystem, the rcbs system showcases the alternative approach.
Choose the RCBS Rock Chucker Supreme Master Reloading Kit if:
- You are a beginner and want the safest, most straightforward start.
- You value your time and want a single, comprehensive purchase.
- You want the confidence of matched, high-quality components from a single brand.
- You load rifle cartridges and appreciate the large press window and leverage.
- You see the value in the included manual and tools as part of the education process.
You pay more initially but likely save money and certainly save time in the long run.
From my honest perspective, for the vast majority of new reloaders, the RCBS kit is the wiser choice. The integrated system, educational manual, and lack of guesswork provide immense value and promote safer practices. The Lee is a fantastic, no-frills press, but it’s best suited as a component in an existing setup or a project for a very specific type of user. For more foundational knowledge, an authority guide on safety is always recommended.
Your reloading press review journey starts with self-assessment. What’s your priority: ultimate low-cost entry or a ready-to-excel toolkit? Answer that, and the choice becomes clear. And remember, no matter which path you choose, investing in solid fundamentals is key. That’s the Honest Opinion from someone who’s seen both benches.
