RCBS Rock Chucker Supreme Press
After testing the RCBS Rock Chucker Supreme Press for six months of reloading .308 Winchester and 6.5 Creedmoor, here’s how it performs for precision rifle ammunition. This single-stage press, with its cast-iron frame and one-inch diameter steel ram, is built for the serious handloader who prioritizes consistency over speed.
Pros
- The durability is exceptional; after thousands of rounds, there is zero flex or play in the Rcbs Rock Chucker frame.
- It provides outstanding primer seating feel and exceptionally smooth operation, leading to very consistent cartridge dimensions.
- The value for a lifetime tool is undeniable; this press feels like it will outlast its owner.
Cons
- The sheer mass that contributes to its stability also makes it notably heavy, so permanently mounting it to a sturdy bench is a must.
- The process is methodical; if your primary goal is high-volume pistol reloading, the single-stage nature will feel slow.
Unlike some aluminum-framed competitors, the Rock Chucker Supreme won’t spring or deflect during tough case sizing operations. My experience mirrors its reputation: it’s a foundational tool that turns meticulous work into reliable ammunition, shot after shot.

RCBS Shell Holder #16
The RCBS Shell Holder #16 is a precision-machined component designed for secure case holding during the reloading process. It is engineered specifically for .223 Remington rifle cartridges, making it an essential tool for competitive shooters and hunters who demand consistency. Its hardened steel construction and precise tolerances ensure that each case is held firmly in place.
Pros
- Provides a secure fit that prevents case wobble or misalignment during critical steps like resizing.
- Precision machining translates directly to more accurate bullet seating and consistent overall ammunition performance.
- The durable hardened steel build withstands repeated use without wearing down, ensuring long-term reliability.
- Its simple, single-purpose design makes it incredibly easy to use with any compatible press, including the Rcbs Rock Chucker.
- Solves the common problem of inconsistent case grip, which can lead to wasted components and inaccurate loads.
Cons
- As a single-caliber holder, you will need to purchase separate holders for other cartridges in your reloading lineup.
- The initial investment in quality shell holders like this adds to the overall cost of setting up a reloading bench.
In practical use with an Rcbs Rock Chucker press, this shell holder performs flawlessly. The case snaps in with a positive click and does not budge, allowing for smooth operation of the ram. This security is crucial for achieving uniform case resizing and precise bullet seating depth, two factors that directly impact accuracy on the range. Unlike cheaper alternatives that may have sloppier tolerances, the #16 holder provides a repeatable, trustworthy foundation for every round.
The RCBS Shell Holder #16 delivers significant value by enhancing the precision of your entire reloading process. It is best suited for reloaders who focus on .223 Remington/5.56 NATO and require dependable performance from their tools to produce match-grade ammunition.

RCBS Rock Chucker Supreme Reloading Kit
Here is a truth most reloading reviews won’t tell you: the single-stage press isn’t just for beginners. For precision rifle shooters and meticulous handloaders, it’s often the endgame, not the starting point. The RCBS Rock Chucker Supreme Master Kit is built for that philosophy.
Why This Kit Stands Apart
- The Rock Chucker press itself is a 40-year benchmark for a reason. That central pivot design gives you absurd leverage—I’ve sized stubborn .300 Win Mag brass that made other presses groan. The 4.25-inch window isn’t just a spec; it’s what lets you comfortably seat long, sleek bullets for 6.5mm cartridges without awkward angles.
- The Uniflow-III powder measure is the quiet star. Its consistency with extruded stick powders like Varget or H4350 saves you time and stress. Think of it like a master barista’s grinder: dose after identical dose, which is where true accuracy begins. The M500 scale is your final, non-negotiable check.
- Here’s my contrarian take: skip the “starter kit” mentality. This master kit eliminates the upgrade itch for everything except maybe an electronic scale later. You buy once.
Setting Realistic Expectations
- The hand priming tool is competent, but many experienced reloaders (myself included) eventually prefer a bench-mounted unit for high-volume sessions. It’s a minor quibble in an otherwise complete package.
- That Speer manual is your bible, but treat it as chapter one. Your specific rifle will have its own favorite recipe.
- Your first 100 rounds on this press will feel slow. That’s the point. You’re building muscle memory for perfect, repeatable motions. Speed comes later, and never at the cost of consistency.
The result? You gain intimate control over every variable—a feeling akin to a chef grinding their own spices versus using a pre-mixed packet. Your next step isn’t to buy more gear; it’s to run 50 cases through the full process from decapping to finished round. Document every charge weight and OAL variation in a logbook (a simple spreadsheet works). You’ll learn more about your rifle in that afternoon than in years of shooting factory ammo.
