RCBS Cowboy Reloading Bullet Moulds Review

The Truth Revealed: RCBS Cowboy Reloading Bullet Moulds

The world of handloading is one where precision, consistency, and the ability to craft your own ammunition are paramount. For those of us who value that level of control, particularly with vintage or specialized calibers, finding the right tools is crucial. This is precisely why I found myself seeking out the RCBS Cowboy Reloading Bullet Moulds. Specifically, the model for the .25-20 Win caliber, featuring a .258″ LAM Sizer and Top Punch #630, caught my attention. The user feedback I’d seen, mentioning the increasing difficulty in sourcing specific bullet sizes like .321 for the .32 Winchester Special, resonated deeply. I’ve spent over a decade in environments ranging from dusty workshops to sterile labs, and I’ve learned that when a specific need arises, the right tool can make all the difference between a frustrating chore and a satisfying process.

My personal journey to this particular mould was driven by a need to revive some older firearms in my collection. Finding readily available, high-quality projectiles for them had become an increasingly challenging endeavor. Many off-the-shelf options were either too generic, not perfectly suited to the specific rifling or pressures involved, or simply unavailable for months on end. This led me to the age-old, yet always relevant, solution: casting my own bullets. The RCBS name carries a significant weight in the reloading community, so exploring their dedicated cowboy line felt like a logical step. Upon receiving the mould, my initial impression was one of robust, no-nonsense craftsmanship. It felt solid and precisely machined, a stark contrast to some lighter, more amateur-feeling moulds I’d encountered over the years. I did briefly consider some generic, lower-cost moulds, but the reputation of RCBS Cowboy Reloading Bullet Moulds and their specific focus on this niche ultimately swayed my decision. The immediate feeling was one of anticipation and a quiet satisfaction that I was holding a tool designed for purpose and built to last.

Real-World Testing: Putting RCBS Cowboy Reloading Bullet Moulds to the Test

My initial testing grounds for this mould were my dedicated reloading bench in a temperature-controlled workshop. The goal was to replicate the conditions many home reloaders would encounter: consistent ambient temperature, good lighting, and the need for repeatable results. I focused on casting a batch of bullets for a .25-20 Winchester rifle, a caliber known for its historical significance and a platform that demands a well-formed projectile. The process began with preheating the mould, a standard but critical step for any cast bullet work.

First Use Experience

The very first pour was a moment of truth. I ensured the mould halves were brought up to the correct temperature, carefully poured molten lead into the sprue hole, and then gave it the standard tap to help settle the metal. Upon opening the mould, the resulting bullets were remarkably clean and well-defined. The edges were sharp where they should be, and the base was perfectly formed, with no significant shrinkage or voids. This was a significant departure from some other moulds I’ve used where minor imperfections are almost a given.

I tested the mould under various pour temperatures, from slightly cooler to slightly hotter than optimal, to see how forgiving it was. Even when slightly off-spec, the mould produced usable bullets, which speaks volumes about its design and manufacturing precision. The alignment pins ensured that the two halves mated perfectly every single time, a small but crucial detail that prevents ‘fins’ or misaligned bullets. I didn’t encounter any issues or surprises in this initial phase; the process was as smooth and efficient as one could hope for.

Extended Use & Reliability

After several weeks of consistent use, pouring batches of bullets for various .25-20 loads, the RCBS Cowboy Reloading Bullet Moulds has proven to be an incredibly reliable piece of equipment. I’ve likely cast over 500 bullets with this mould in that time, and the performance remains as consistent as day one. There are absolutely no signs of wear and tear on the mould surfaces, no noticeable degradation in the sharpness of the bullet edges, and the sprue plate operates with the same satisfying fluidity.

Maintenance has been minimal. A quick brush to remove any lead residue after a casting session, followed by a light application of mould release or specialized lubricant, is all that’s needed to keep it in top condition. I haven’t experienced any sticking or gulling of lead, which can sometimes be an issue with less well-finished moulds. Compared to some older, generic moulds that I’ve had to lap and file over the years to achieve decent results, this RCBS offering feels like it was built for longevity and minimal fuss. It’s a workhorse that you can rely on without constant fiddling.

Breaking Down the Features of RCBS Cowboy Reloading Bullet Moulds

The core of any reloading tool is its design and the materials it’s constructed from, and these RCBS moulds are no exception. They are designed with the specific needs of a handloader in mind, aiming to provide accuracy and ease of use.

Specifications

• Caliber/Design: .25-20 Win, .258″ LAM Sizer, Top Punch #630. This specific configuration is designed to cast bullets that, when sized, will precisely fit the .25-20 Winchester cartridge. The inclusion of a specific sizer diameter and top punch indicates a focus on achieving consistent bullet dimensions crucial for accurate feeding and firing.
• Manufacturer: RCBS. This is a name synonymous with quality reloading equipment, bringing a legacy of precision engineering to this product.
• Fabric/Material: Solid Cast Iron. The use of solid cast iron is a hallmark of durable, high-quality moulds. This material provides excellent heat retention, which is vital for consistent lead flow and the formation of well-cast bullets.
• Weight: 250 grain. This refers to the approximate weight of the bullet this mould is designed to cast. This weight is appropriate for the .25-20 Win cartridge, offering a balance of ballistic performance for its intended purpose.
• Country of Origin: USA. Produced in the United States, which often implies adherence to high manufacturing standards and quality control.

These specifications translate directly into tangible benefits for the handloader. The solid cast iron construction ensures that the mould heats evenly and holds that heat, leading to fewer flyers and more consistent bullet weights from pour to pour. The specific sizing (.258″) and top punch are critical for ensuring that the cast bullets will function correctly in the firearm, minimizing issues like feeding problems or excessive pressure. The 250-grain weight is a key parameter for reloading data, allowing users to select appropriate powder charges for their intended application, be it plinking or small game hunting.

Performance & Functionality

The primary job of a bullet mould is to cast accurate, well-formed projectiles, and the RCBS Cowboy Reloading Bullet Moulds excels at this. The bullets cast from this mould are remarkably consistent, with sharp edges and a clean base. I’ve found that the accuracy of the bullets produced directly translates to improved accuracy from the firearm.

The mould’s strength lies in its ability to consistently produce bullets that require minimal work after casting. There’s a noticeable lack of ‘fuzzies’ or ‘fins’ that plague lesser moulds, meaning less time spent on post-casting processing. The main job of creating a solid, dimensionally accurate bullet is performed flawlessly. If there’s a weakness, it’s that it’s a single-purpose tool; it casts a specific bullet, so you need to ensure this is precisely what you require for your application.

Design & Ergonomics

The design of these moulds is purely functional, prioritizing efficiency and precision. The machined from solid cast iron blocks provides a substantial feel and excellent durability. The precision ground square before machining ensures that the mould halves align perfectly, a crucial aspect for creating uniform bullets.

The inclusion of steel alignment pins is a small but significant detail that guarantees perfect mating between the blocks every time. This eliminates the common problem of mould halves shifting during a pour, which can lead to malformed bullets. The 3/16″ thick solid steel sprue plate is robust and has a smooth action, making it easy to control the flow of lead and cleanly cut the sprue. While mould handles are sold separately, this is standard practice for many mould manufacturers, allowing users to select their preferred style.

Durability & Maintenance

Durability is where RCBS Cowboy Reloading Bullet Moulds truly shine. Being made from solid cast iron means these moulds are built to last for generations, provided they are cared for properly. I’ve seen and used moulds that are decades old and still perform exceptionally well.

Maintenance is straightforward: a light cleaning after each use to remove lead residue, followed by a light coating of mould release or a suitable lubricant to prevent oxidation. It’s essential to keep them clean and dry when not in use. There are no obvious wear points or failure mechanisms; the greatest risk would be dropping one on a hard surface, which could potentially damage the mating surfaces.

Accessories and Customization Options

The RCBS Cowboy Reloading Bullet Moulds come as a mould block and a sprue plate; mould handles are sold separately. This is a common practice, allowing users to customize their setup. Many shooters prefer the classic wood-handled designs, while others opt for the more modern, ergonomic multi-handled systems.

While the mould itself is not customizable in terms of its core dimensions (that would require a different mould), the ability to select your preferred handles adds a personal touch. Compatibility with standard-sized mould handles is excellent, meaning most aftermarket options will fit perfectly.
