Let’s Dive into RCBS Exp-Decapping Tapered Units
Reloading ammunition is a meticulous process, and like any precision craft, it demands reliable components. When I started reloading bottleneck cartridges, the decapping and neck expanding stage quickly became a source of frustration with inconsistent results and the occasional bent decapping pin. That’s when I discovered the RCBS Exp-Decapping Tapered Units, a seemingly simple but profoundly effective solution.
I was looking for a way to improve the consistency of my reloads and reduce the likelihood of damaging my brass. I needed a system that would smoothly de-prime and expand the case neck without excessive stress or deformation. The promise of concentricity and smooth operation drew me to these units.
Upon opening the package, I was immediately struck by the simplicity of the design. These aren’t flashy, but exude quality. The precision machining was evident, and the unit felt robust in hand. Compared to the standard decapping pins included with my die sets, these looked like a serious upgrade. I chose the RCBS Exp-Decapping Tapered Units over similar products from Lee and Hornady because of RCBS‘s reputation for quality and the positive feedback I’d seen from other reloaders. My initial excitement was tempered with cautious optimism, hoping they would live up to the hype.
Real-World Testing: Putting RCBS Exp-Decapping Tapered Units to the Test
First Use Experience
My first experience with the RCBS Exp-Decapping Tapered Units was at my reloading bench, preparing .308 Winchester cases for a precision rifle build. I ran several batches, carefully monitoring the effort required and the resulting case neck dimensions. The units performed flawlessly, even with some heavily crimped military surplus brass.
I tested them under varying conditions. From relatively clean, once-fired brass to some older, slightly tarnished range pickups, the units maintained consistent performance. The tapered expander ball smoothed out the neck expanding process, requiring less force than the standard expander button I was used to. There were no surprises, just smooth, consistent decapping and neck expansion.
Extended Use & Reliability
After several months of use, the RCBS Exp-Decapping Tapered Units have proven to be a reliable and valuable addition to my reloading setup. I’ve processed thousands of cases, and they’re still going strong. There’s been no noticeable wear and tear.
The units have proven durable even when encountering stubborn crimps or slightly off-center primer pockets. Maintenance is incredibly simple, requiring only occasional cleaning with a brush and solvent to remove accumulated residue. Compared to my previous experiences with bent decapping pins and inconsistent neck tension, the RCBS Exp-Decapping Tapered Units have been a significant upgrade, saving me time and frustration.
Breaking Down the Features of RCBS Exp-Decapping Tapered Units
Specifications
The RCBS Exp-Decapping Tapered Units consist of three primary components: the expander rod, the expander ball, and the decapping pin. They are designed for use in sizing dies, performing the dual function of removing spent primers and expanding the case neck in bottleneck cartridges. RCBS utilizes precision machining in the construction, and the units are silver in color. Each package contains one complete unit, and these parts are proudly made in the USA. These specifications highlight the unit’s focused functionality and RCBS‘s commitment to quality manufacturing.
These specifications are important because they contribute directly to the consistency and reliability of the reloading process. Precision machining ensures concentricity, which is crucial for accuracy. The tapered expander ball allows for smoother neck expansion, reducing case neck runout. The USA-made quality means I can trust the durability of the product.
Performance & Functionality
The RCBS Exp-Decapping Tapered Units perform their job exceptionally well. They reliably remove primers and expand case necks with consistent force and precision. The tapered expander ball significantly reduces the force needed to expand the neck, resulting in less stress on the brass.
The strength of these units lies in their simplicity and reliability. The only real weakness is that they are specific to bottleneck cartridges. They meet and exceed my expectations. The level of consistency and reduction in damaged cases has made reloading more efficient and enjoyable.
Design & Ergonomics
The design of the RCBS Exp-Decapping Tapered Units is simple and functional. They are made from durable, high-quality materials. The unit’s weight is negligible, but the components are robust enough to withstand repeated use.
The units are exceptionally user-friendly. There is no learning curve. Installation is straightforward. Replacing the standard decapping pin and expander in my sizing die took only a few minutes.
Durability & Maintenance
These units are built to last. The precision-machined components are resistant to wear and tear. With proper care, they should last for thousands of rounds.
Maintenance is minimal. A quick cleaning with a brush and solvent after each reloading session is all that’s needed to keep them in top condition. The simple design also makes them easy to inspect and, if necessary, replace individual parts.
Accessories and Customization Options
The RCBS Exp-Decapping Tapered Units come as a complete unit, with no additional accessories included. However, they are compatible with a wide range of RCBS sizing dies and aftermarket decapping pins. Reloaders can also experiment with different expander ball sizes to fine-tune neck tension for specific bullet diameters.
The ability to use different expander ball sizes offers a degree of customization that allows reloaders to optimize their loads for accuracy. While there aren’t many “accessories,” the interchangeability with other RCBS components is a significant benefit.
Pros and Cons of RCBS Exp-Decapping Tapered Units
Pros
- Increased Reloading Consistency: Provides consistent decapping and neck expansion, leading to more uniform bullet seating and improved accuracy.
- Reduced Case Damage: Tapered expander ball minimizes stress on the case neck, reducing the risk of splitting or cracking.
- Improved Smoothness: The tapered design results in smoother operation, requiring less force and reducing the risk of stuck cases.
- Durable Construction: Precision-machined from high-quality materials, ensuring long-lasting performance.
- Easy Maintenance: Simple design makes cleaning and maintenance quick and easy.
Cons
- Only compatible with bottleneck cartridges.
- Requires resizing die body (not included).
Who Should Buy RCBS Exp-Decapping Tapered Units?
The RCBS Exp-Decapping Tapered Units are perfect for reloaders who seek consistent, reliable results and want to minimize case damage. They are especially beneficial for reloaders who focus on accuracy, such as precision rifle shooters and competitive marksmen. They are also a good investment for reloaders who process large volumes of brass, as the increased durability and reduced case damage will save time and money in the long run.
Reloaders who only load straight-walled pistol cartridges should skip this product. Also, reloaders who are happy with the performance of their existing decapping system and do not experience issues with case damage or consistency may not see a significant benefit.
A must-have accessory would be a high-quality case lubricant to further reduce friction during the resizing process. An RCBS case neck brush can help ensure consistent neck tension.
