Two names dominate the conversation for a first serious single-stage press. On one side, you have the legendary RCBS Rock Chucker Supreme, often sold as a complete master kit. On the other, Frankford Arsenal’s modern M-Press offers a unique coaxial design. Both promise to turn components into ammunition, but their approaches and packages are worlds apart. This isn’t just about a press; it’s about your entire reloading workflow from day one.
between them means weighing decades of proven reputation against innovative engineering. You’re investing in a tool that could last a lifetime, so the decision carries weight. Let’s break down this reloading press showdown feature by feature, kit by kit, to find which one earns a permanent spot on your bench.
The Contenders in the Single-Stage Arena
Frankford Arsenal’s M-Press stands out immediately with its two parallel guide rods and floating shell-holder plate. This coaxial design aims for perfect alignment and smooth operation right out of the box. It’s a heavy-duty unit with a die-cast construction, weighing in at 21 lbs with dimensions of 20″ L x 9″ W x 6.5″ D. The package includes quick-change die blocks that fit standard 7/8″-14 dies and a spent primer catcher.
The RCBS Rock Chucker Supreme is the undisputed benchmark. Its reputation is built on a massive cast iron frame and a central pivot design providing tremendous leverage. The press features a spacious 4.25″ window for long magnum cases and an ambidextrous handle. However, its real power comes from being the heart of the Supreme Master Reloading Kit, which surrounds it with virtually every accessory a new reloader needs.
Head-to-Head Feature & Specification Breakdown
This single stage press comparison highlights a fundamental difference: a standalone innovative press versus a complete traditional system. The table below lays out the core specifications based on their designs and stated features.
| Feature | Frankford Arsenal M-Press | RCBS Rock Chucker Supreme Kit |
|---|---|---|
| Press Frame | Heavy-duty, robust die-cast construction | Legendary cast iron construction |
| Frame Design | Coaxial with 2 parallel guide rods for stability | Central pivot design for outstanding leverage |
| Key Innovation | Integral floating shell-holder plate | Ambidextrous handle, 4.25″ loading window |
| Primer Management | Includes spent primer catcher | Includes separate Hand Priming Tool |
| Die Compatibility | Quick-change blocks fit standard 7/8″-14 dies | Accepts standard 7/8″-14 dies directly |
| Dimensions & Weight | 20″ L x 9″ W x 6.5″ D, 21 lbs | Press is substantial; full kit includes many components |

From my honest perspective, the M-Press design prioritizes precise, friction-free operation with its guided ram. The Rock Chucker screams brute strength and leverage with its simple, massive pivot. One isn’t inherently better; they are different philosophies for achieving the same goal.
Warranty & Customer Service: The Long-Term Factor
This is a critical entity often overlooked. RCBS has built a legendary status partly on its “No Excuses” warranty, which is a huge consideration for a lifelong tool. Frankford Arsenal, backed by Battenfeld Technologies, also offers solid support. My honest take is that for a beginner, the peace of mind from a company known for hassle-free warranty service (RCBS) can be a significant tie-breaker. For the tinkerer who values the modern design, Frankford’s support is more than adequate.
Price, Value & What’s in the Box
The value proposition here is the most dramatic differentiator. You are comparing a single press to a comprehensive starter kit. Honestly speaking, this makes a direct price comparison almost irrelevant without context.
The Frankford Arsenal M-Press is sold as a press with die blocks and a primer catcher. You will need to purchase every other accessory separately: scale, powder measure, calipers, case prep tools, and a reloading manual. This allows for ultimate customization but a higher total entry cost.
The RCBS Rock Chucker Supreme Master Kit is the opposite. It includes:
- Rock Chucker Supreme Press
- Uniflow-III Powder Measure (noted for consistent charges)
- M500 Mechanical Scale (505-grain capacity, +/-0.1-grain accuracy)
- Hand Priming Tool
- Universal Case Loading Block, Debur Tool, Case Lube Kit, Powder Funnel
- Hex Key Set and the Speer Reloading Manual
To be completely honest, asking does the RCBS Rock Chucker kit include all necessary accessories? gets a resounding “almost.” You still need dies, shell holders, calipers, and the cases, powder, and primers themselves. But it provides the core tools to perform every reloading step. The kit’s contents are its greatest strength, arguably making it the best reloading press for beginners from a sheer convenience standpoint.
Performance & User Experience: Ergonomics & Results
Ergonomics and Daily Use
The M-Press’s floating shell holder and guided ram promise exceptionally smooth operation, potentially reducing effort on tough resizing operations. The spent primer system is integrated. Speaking honestly, the innovative feel is a real draw.
The Rock Chucker is about proven, brute-force leverage. Its ambidextrous handle and massive frame make sizing stubborn brass feel routine. The priming, however, is done off-press with the included hand tool, which many precision reloaders prefer for tactile feedback. The debate of Frankford Arsenal M-Press vs RCBS Rock Chucker Supreme for a beginner often hinges here: learn on an integrated system or the separate, arguably more precise, hand-priming method.
Precision and Long-Term Maintenance
For the question of which is better for precision rifle reloading Frankford Arsenal M-Press or RCBS Rock Chucker, both are capable. The M-Press’s coaxial design theoretically offers perfect alignment for superior concentricity. The Rock Chucker’s immense press frame strength and lack of flex provide a different kind of consistency. Honestly, the shooter’s technique and the quality of the dies will outweigh the mechanical difference between these two presses for most users.
Long-term maintenance is simple for both. The Rock Chucker’s cast iron may need occasional rust prevention in humid climates. The M-Press’s guide rods should be kept clean and lightly lubricated. From my honest assessment, the Rock Chucker’s simpler design has a slight edge in proven, decades-long durability with minimal upkeep, which is why Rock Chucker durability is so often cited.
It’s worth checking other precision focused comparisons, like how the M-Press stacks up against other classics, to get a wider view of the market.
Final Verdict: Who Should Buy Which Press?

The Rock Chucker Kit is an entire reloading system anchored by an icon. For the newcomer, the RCBS kit’s comprehensiveness is almost impossible to beat, eliminating the paralysis of choosing individual components. For the reloader adding a dedicated single-stage or who loves innovative mechanics, the M-Press is a compelling and excellent option.
