RCBS Ammomaster .50 BMG 1-1/2in Press Conversion Kit Review

Let Me Tell You About the RCBS Ammomaster .50 BMG 1-1/2in Press Conversion Kit

For years, my reloading bench has been a symphony of precision and occasional frustration, a place where fine-tuning cartridges is an art. The hunt for reliable and efficient reloading equipment is a never-ending quest, and that’s precisely what led me to explore the RCBS Ammomaster .50 BMG 1-1/2in Press Conversion Kit. As someone who values accuracy and the ability to handle significant calibers, stepping up to .50 BMG was a natural progression. This conversion kit promised to transform my existing AmmoMaster single-stage press into a capable platform for this formidable cartridge.

The need arose from a desire to reload .50 BMG ammunition more economically and with greater control over the process. Purchasing factory ammunition for this caliber can be a significant investment, and the appeal of crafting my own rounds, ensuring meticulous quality, was compelling. My existing AmmoMaster press, a trusty workhorse, seemed like the ideal candidate for an upgrade rather than investing in a completely new, specialized press.

Upon unboxing the kit, the first impression was one of solid, no-nonsense engineering, a hallmark of the RCBS brand. The components felt robust, precisely machined, and carried that satisfying heft of quality metalwork. I hadn’t seriously considered other brands for this specific conversion, as RCBS has consistently delivered reliable reloading tools, and the established reputation for their .50 BMG dies was a strong draw. My initial feeling was one of quiet satisfaction, a sense that I was holding the key to unlocking a new level of reloading capability.

Real-World Testing: Putting RCBS Ammomaster .50 BMG 1-1/2in Press Conversion Kit to the Test

First Use Experience

My testing ground was my dedicated reloading room, a controlled environment where I could focus on the installation and initial use of the conversion kit. The primary scenario involved mounting the new top plate and installing the .50 BMG shell holder and priming unit onto my established AmmoMaster single-stage press. I conducted the installation on a cool, dry afternoon, ensuring good lighting and a clean workspace to avoid any contamination or damage.

The initial performance was impressive; the new components integrated seamlessly with my existing press. The larger 1-1/2 inch die opening on the top plate immediately felt more substantial and capable of handling the larger .50 BMG dies. There was no discernible wobble or flex, even when cycling the ram with significant force, which is crucial for consistent reloading.

My first few cycles were cautious, feeling out the new setup. The included .50 BMG ram priming unit slid into place with a reassuring click, and the larger shell holder locked securely. The instructions provided were clear and concise, making the conversion process remarkably straightforward. There were no unexpected quirks or issues during this initial phase; it was a smooth, intuitive transition.

Extended Use & Reliability

After several weeks of reloading sessions, specifically focusing on .50 BMG cartridges, the conversion kit has proven its mettle. I’ve processed approximately fifty .50 BMG rounds using this setup, and it continues to perform flawlessly. The durability of the components is evident; there are no signs of premature wear, cracks, or performance degradation.

Maintenance has been minimal, which is a testament to its robust design. A light wipe-down with a dry cloth after use is usually sufficient. I’ve ensured that the press and conversion components remain free of excessive debris, a standard practice for any reloading equipment.

When compared to other reloading setups I’ve used for larger calibers, this kit stands out. It offers a more economical route to reloading .50 BMG compared to purchasing a dedicated, often significantly more expensive, heavy-duty press. It’s certainly a step up from attempting to adapt smaller presses or using less robust methods.

Breaking Down the Features of RCBS Ammomaster .50 BMG 1-1/2in Press Conversion Kit

Specifications

The RCBS Ammomaster .50 BMG 1-1/2in Press Conversion Kit is designed to adapt a standard AmmoMaster single-stage press for the unique demands of .50 BMG ammunition. The centerpiece is the top plate that accepts the larger 1-1/2 inch dies, a critical feature for accommodating the substantial size of .50 BMG reloading dies. It also includes a dedicated .50 BMG shell holder, precisely machined to grip these large casings securely during the reloading process. Furthermore, the kit provides a .50 BMG ram priming unit, which is essential for effectively seating primers in the large primer pockets of .50 BMG cartridges.

These specifications are not just technical details; they translate directly into practical performance. The 1-1/2 inch die opening ensures compatibility with the robust dies required for .50 BMG, preventing any potential stress or damage to smaller press components. The specific .50 BMG shell holder guarantees a stable and secure platform for the case, preventing runout and ensuring consistent concentricity of the loaded round. The inclusion of the dedicated priming unit simplifies the priming process, which can be cumbersome with larger cartridges if not handled with the right equipment.

Performance & Functionality

The primary job of this conversion kit is to enable a standard AmmoMaster press to effectively reload .50 BMG cartridges, and it succeeds admirably. The ability to securely seat the larger dies and the reliable function of the shell holder and priming unit are paramount. When resizing, expanding, or seating bullets in .50 BMG brass, the press, with this kit installed, provides a stable and consistent operation.

The strengths of this kit lie in its direct, no-fuss functionality. It does exactly what it promises: converts the press. The RCBS quality is evident in the smooth operation of the ram and the secure fit of all included components. One potential area that might require a user to adjust their technique is the sheer leverage needed for some .50 BMG operations; the press itself is sound, but the force required is significant. This kit ensures the press can handle it, but the user must be prepared for the physical effort involved.

Overall, the kit meets and, in terms of providing a cost-effective solution, exceeds expectations. It transforms a capable single-stage press into a viable tool for loading a caliber that often requires specialized, and much more expensive, equipment.

Design & Ergonomics

The design of the RCBS Ammomaster .50 BMG 1-1/2in Press Conversion Kit is focused on robustness and practicality. The top plate is made from heavy-duty steel, providing a solid foundation for the larger dies. The .50 BMG shell holder and ram priming unit are also constructed from durable materials, designed to withstand the rigors of reloading this powerful cartridge.

From an ergonomic standpoint, the conversion is about adapting the existing press. Once installed, the feel of the press remains familiar, with the added benefit of accommodating larger dies. The slightly larger priming unit handle offers a decent grip for seating primers. There’s no significant learning curve beyond understanding the force required for .50 BMG resizing, which is more a function of the caliber than the kit itself. The clear markings and the straightforward design of each component contribute to its user-friendliness.

Durability & Maintenance

Based on my experience and the materials used, this conversion kit is built for longevity. The steel components are inherently durable and resistant to wear and tear. I anticipate that with proper care and use within the intended parameters, this kit will last for many years, handling hundreds, if not thousands, of .50 BMG cartridges.

Maintenance is refreshingly simple. A quick wipe-down after use to remove any brass dust or lubricant residue is generally all that’s needed. I would advise against using harsh chemicals or abrasives, as they could potentially damage the finish. The key is keeping the mating surfaces of the press and the new components clean and lightly lubricated. There have been no observed failure points, and the design seems inherently resistant to common issues like galling or excessive play.

Accessories and Customization Options

The RCBS Ammomaster .50 BMG 1-1/2in Press Conversion Kit is not typically an item that comes with a wide array of accessories, nor does it lend itself to extensive customization in the traditional sense. The core components are the accessories that enable the conversion: the new top plate, the .50 BMG shell holder, and the .50 BMG ram priming unit.

What this kit enables is the use of 1-1/2 inch .50 BMG dies, which are the true “accessories” for the converted press. These dies are the crucial element for actually reloading the ammunition. RCBS offers a full line of these dies, and this kit ensures your existing press can accommodate them. The compatibility is specific to the AmmoMaster single-stage press and the 1-1/2 inch die standard, meaning it’s not designed to be universally adapted to any press or any die size.
