RCBS Cowboy 12 Gauge Brass Shot Shell Dies Review

Uncovering the RCBS Cowboy 12 Gauge Brass Shot Shell Dies: Real Review

The pursuit of authenticity in Cowboy Action Shooting often extends beyond the firearms themselves. Many enthusiasts seek to replicate historical ammunition, and for 12 gauge shotgunners, this means working with brass shotshells. This is precisely where the RCBS Cowboy 12 Gauge Brass Shot Shell Dies come into play, offering a dedicated solution for reloaders looking to maintain period-correct aesthetics. As an experienced gear specialist with over a decade of real-world application across diverse environments, I was keen to see if these dies lived up to the promise of precision and authenticity.

My journey to this specific die set was driven by a growing frustration with the aesthetic disconnect when using modern plastic hulls in my historical firearms. While functionally sound, the visual contrast simply didn’t align with the immersive experience I strive for at Cowboy Action matches. I needed a way to faithfully reproduce the look and feel of traditional shotshells without compromising safety or functionality.

Upon arrival, the initial impression was one of typical RCBS robustness. The dies possess a satisfying heft, suggesting quality materials and precise machining. The included components felt solid, giving me confidence in their longevity. I briefly considered less specialized die sets or attempting to adapt other tooling, but the specialized nature of these RCBS dies promised a more streamlined and reliable process, specifically tailored for brass hulls. My immediate reaction was a sense of quiet anticipation, a feeling that a long-standing reloading puzzle might finally be solved.

Real-World Testing: Putting RCBS Cowboy 12 Gauge Brass Shot Shell Dies to the Test

My primary testing ground for these dies was my home reloading bench, a space that has seen everything from delicate laboratory instruments to rugged workshop tools. I employed a standard RCBS single-stage press, a staple in my setup for its reliability and compatibility. The RCBS Cowboy 12 Gauge Brass Shot Shell Dies were tested with various brands of used 12 gauge brass hulls, ensuring a broad spectrum of fit and potential challenges.

The initial setup was remarkably straightforward, fitting perfectly into the press’s bushing system. Sizing and de-priming the brass hulls was surprisingly smooth; the dies worked through the aged brass with an almost effortless feel. I did encounter a minor issue with a particularly stubborn primer on one of the older hulls, but this was more a reflection of the hull’s condition than a fault of the die itself.

After weeks of regular use, these dies have proven to be exceptionally reliable. My reloading sessions now routinely involve processing a batch of brass hulls, and the performance of the RCBS Cowboy 12 Gauge Brass Shot Shell Dies remains consistent. There are no noticeable signs of wear on the dies themselves, and they continue to size and crimp with the same precision as day one. Maintenance is minimal, requiring only a light wipe-down and occasional application of a quality lubricant to the press and dies.

Compared to previous experiences with generic reloading tools that required significant trial-and-error for specialized tasks, these dedicated shotshell dies are a revelation. They perform precisely as intended, eliminating the guesswork and frustration often associated with reloading non-standard ammunition types. They represent a significant upgrade in both efficiency and outcome.

Breaking Down the Features of RCBS Cowboy 12 Gauge Brass Shot Shell Dies

Specifications

The RCBS Cowboy 12 Gauge Brass Shot Shell Dies set includes the essential components for resizing, de-priming, and finishing brass shotshells. The primary die performs the crucial sizing and de-priming function, bringing previously fired brass hulls back to their original dimensions. This process is critical for ensuring proper fit in both the firearm and subsequent reloading steps.

The set is designed for 12 Gauge shells, with a quantity of 1 die set included, as is standard for most reloading die configurations. The material composition inherently points to Brass as the material for the hulls being worked with, and the dies themselves are constructed from hardened steel for durability. These specifications are fundamental for the precise metal deformation required in reloading shotshells.

The Gun Type indicated is Shotgun, and crucially for many domestic reloaders, these dies are manufactured in the USA. This commitment to domestic manufacturing often translates to high-quality control and adherence to stringent production standards, which is a hallmark of the RCBS brand. The robust construction ensures these dies can withstand the repeated stresses of resizing and crimping brass cases over many reloading cycles.

Performance & Functionality

The core job of the RCBS Cowboy 12 Gauge Brass Shot Shell Dies is to prepare brass shotshells for reloading, and in this, they excel. The resizing die effectively removes any bulges or dents, returning the hull to a uniform diameter. This is paramount for reliable chambering and ejection of reloaded shells.

The de-priming function is also robust, clearing out spent primers efficiently. The sizing ring, a key feature, ensures that even heavily used brass hulls can be revived for another life. While these dies don’t handle the powder, wad, or shot insertion—those tasks fall to a dedicated shotshell press—they provide the essential foundation for successful brass hull reloading.

The finishing crimp, achieved by removing the sizing ring and installing the finish crimp die, creates a neat, professional-looking roll crimp. This not only enhances the authentic appearance but also ensures the over-shot card and shot remain securely contained. The performance is consistent, resulting in shells that look and feel authentic.

Design & Ergonomics

The design of these RCBS dies is purely functional, prioritizing precision and durability over elaborate aesthetics. They are engineered to work within a standard RCBS single-stage press equipped with removable die bushings. The fit and finish are typical of RCBS products: clean machining, with no rough edges or imperfections.

Ergonomically, the dies are handled during setup and adjustment rather than repeated manipulation during the reloading cycle. Once installed and adjusted, the press lever does the work. The feel of the hardened steel and the precise threading speak to the quality of the materials and manufacturing.

The die components are clearly marked, indicating their purpose, which simplifies the setup process. The sizing ring is distinct and easily removable when transitioning to the crimping step. This straightforward design philosophy ensures that the user can focus on the reloading process without unnecessary complexity.

Durability & Maintenance

Given their construction from hardened steel, the RCBS Cowboy 12 Gauge Brass Shot Shell Dies are built for longevity. Under normal reloading conditions, these dies should last for a lifetime of use. The inherent nature of reloading brass hulls means the dies are subjected to significant force, but the robust build quality mitigates wear.

Maintenance is minimal; a light application of a good quality reloading press lubricant on the threads and internal surfaces of the sizing die will keep them operating smoothly. After each reloading session, a quick wipe-down with a clean cloth to remove any brass dust or residue is sufficient. There are no complex parts to break or delicate mechanisms that require special care.

The primary potential for “failure” would come from extreme misuse, such as dropping the dies repeatedly on a hard surface or allowing them to rust, which is easily preventable with basic care. The lack of intricate parts means fewer points of potential mechanical failure compared to more complex reloading tools.

Accessories and Customization Options

This particular die set, the RCBS Cowboy 12 Gauge Brass Shot Shell Dies, is designed as a specialized component for a reloading press. It does not typically come with a wide array of accessories in the traditional sense. The set inherently includes the necessary dies for resizing, de-priming, and crimping.

Compatibility with other brands is generally limited to presses that accept standard 7/8″-14 thread reloading dies and feature removable die bushings. The critical element is the RCBS single-stage press or equivalent that allows for the necessary press stroke and die retention. There are no other significant customization options for the dies themselves.

The true “customization” comes in the form of the ammunition you create. These dies enable the meticulous reloader to craft authentic-looking brass shotshells, which is the primary goal for users seeking this specific product. The effectiveness of these dies is in their ability to facilitate this specific type of reloading.

Pros and Cons of RCBS Cowboy 12 Gauge Brass Shot Shell Dies

Who Should Buy RCBS Cowboy 12 Gauge Brass Shot Shell Dies?

The RCBS Cowboy 12 Gauge Brass Shot Shell Dies are unequivocally for the dedicated Cowboy Action Shooter or historical firearm enthusiast who prioritizes authenticity in their ammunition. If you are involved in historical reenactments or simply want to achieve the most period-correct look for your black powder shotgun loads, this set is an essential tool. It is also for the reloader who appreciates the tactile experience and visual appeal of brass shotshells, and who wants to do it the right way.

However, individuals seeking a general-purpose shotshell reloading die set for modern plastic hulls should look elsewhere.

For those who do invest, consider pairing these dies with a quality shotshell loading press and a scale for precise powder charges. Ensuring you have a good supply of clean brass hulls is also paramount. A good set of reloading manuals or online resources specific to shotshell reloading with brass hulls will also enhance the experience.
