RCBS 3-Die Carbide Taper Crimp Set – Group E – Straight Walled Cartridges Review

This is What Happened When I Used the RCBS 3-Die Carbide Taper Crimp Set – Group E – Straight Walled Cartridges

As a seasoned gear and equipment specialist with over a decade of hands-on experience across diverse environments, I’ve seen my fair share of reloading components. My journey into precision reloading, particularly for straight-walled pistol cartridges, often leads me to seek out the most reliable and efficient tools. Recently, a need arose for a dependable set of dies to ensure consistent case resizing, expansion, and a proper taper crimp for a variety of common pistol calibers. This led me to the RCBS 3-Die Carbide Taper Crimp Set – Group E – Straight Walled Cartridges, a name synonymous with quality in the reloading world. The prospect of a carbide sizing die, eliminating the mess of case lube, and a dedicated taper crimp die for headspacing control was particularly appealing.

My primary motivation for acquiring this set was the desire for repeatable accuracy and ease of use. In my workshop, where time is often at a premium, anything that streamlines the reloading process without sacrificing quality is a win. I’d been using a different brand’s steel sizing die, which required constant lubrication, and while functional, it added an extra step and potential for mess. The idea of a maintenance-free carbide sizer was a significant draw. Competitors offer similar 3-die sets, but RCBS’s reputation for precision machining and durability made it my top choice. My first impression upon unpacking was one of solid craftsmanship; the dies felt substantial and well-finished.


Real-World Testing: Putting RCBS 3-Die Carbide Taper Crimp Set – Group E – Straight Walled Cartridges to the Test

First Use Experience

My initial testing took place at my reloading bench in the controlled environment of my workshop. I decided to start with a batch of .45 ACP brass that had been through several firing cycles, varying in condition from slightly dented to mildly oxidized. The process of setting up the dies on my progressive press was straightforward, as is typical for RCBS tooling. I appreciated the clear instructions and the familiar feel of their die bodies.

The first few cases through the carbide size die were a revelation. The absence of case lube was immediately noticeable; no sticky residue on the cases, no need to wipe them down, and no lubricant buildup on the press or dies themselves. This single aspect significantly sped up the initial sizing and de-priming process. The expander die performed as expected, consistently flaring the case mouths to the precise dimension needed for bullet seating, with no signs of over-expansion or stress on the brass. Finally, the taper crimp seater die applied a clean, uniform crimp, ensuring proper headspacing without collapsing the case mouth excessively.

Extended Use & Reliability

Over several weeks, I used this RCBS die set to reload thousands of rounds across multiple straight-walled pistol calibers, including 9mm Luger, .40 S&W, and .45 Colt, in addition to the initial .45 ACP batch. The carbide sizing die consistently performed without requiring any lubrication, even with brass that had been fired in different firearms and exhibited some grime. There were no instances of brass sticking in the die, which can be a frustrating issue with less precise tooling.

The durability of the carbide rings is evident; after extensive use, there are no visible signs of wear or degradation in their sizing performance. The expander plug has also held up well, maintaining its dimensions and consistent flare. The taper crimp function of the seating die remains precise, producing cartridges that chamber and headspace flawlessly in my firearms. Cleaning is minimal – a quick wipe-down of the die bodies and a check of the seating stem is all that’s needed. Compared to my previous steel dies, the maintenance requirements are vastly reduced, saving considerable time and effort.

Breaking Down the Features of RCBS 3-Die Carbide Taper Crimp Set – Group E – Straight Walled Cartridges

Specifications

The RCBS 3-Die Carbide Taper Crimp Set – Group E – Straight Walled Cartridges is designed for handloaders working with straight-walled pistol cartridges. It consists of three essential dies: a carbide size die, an expander die, and a taper crimp seat die. The carbide construction of the sizing die is a standout feature, meaning no case lubrication is required, which is a significant advantage for workflow efficiency and cleanliness.

The expander die is precisely machined to open the case mouth to the correct diameter, preparing it for bullet insertion and imparting a slight bell or flare. The taper crimp seat die performs the dual function of seating the bullet to the correct depth and applying a taper crimp. This taper crimp is crucial for proper cartridge headspacing, ensuring reliable feeding and extraction. These dies are manufactured to RCBS’s high standards, ensuring accuracy and longevity. The set typically comes packaged in the manufacturer’s signature green box.

Performance & Functionality

In terms of core function, this die set excels. The primary job of resizing and de-priming brass is handled with effortless precision by the carbide size die. Cases are returned to their correct dimensions without the fuss of lubrication, which is a game-changer for volume reloaders. The expander die consistently provides the perfect amount of case mouth flare, allowing for smooth bullet seating without damage to the case or bullet.

The taper crimp applied by the third die is particularly noteworthy. It’s designed to remove the bell from the case mouth without overly reducing the case diameter, which is ideal for many semi-automatic pistol cartridges. This results in cartridges that feed reliably from magazines and headspace correctly in the chamber. The overall consistency across hundreds of loaded rounds has been exceptional, leading to more accurate and dependable reloads. While it’s designed for straight-walled cartridges, it performs that specific task exceptionally well.

Design & Ergonomics

The design of the RCBS 3-Die Carbide Taper Crimp Set – Group E – Straight Walled Cartridges is classic and functional. The dies are constructed from durable steel with hardened carbide inserts for the sizing ring. Their weight and feel are substantial, conveying a sense of quality and robustness.

The knurled bands on the die bodies provide a secure grip for adjustment and removal from the press, even with slightly greasy hands. The seating stem in the seater die is well-designed for consistent bullet seating depth. While there’s no complex ergonomics involved, the straightforward, tool-like design ensures ease of use and minimal learning curve for anyone familiar with progressive presses.

Durability & Maintenance

Based on my extensive use and RCBS’s reputation, the durability of this die set is excellent. The carbide sizing ring is inherently harder and more wear-resistant than steel, meaning it should provide consistent sizing performance for tens of thousands of rounds, if not more. The overall construction is robust, and there are no small, easily broken parts to worry about.

Maintenance is remarkably simple. Because the carbide size die doesn’t require lubrication, the primary need is to keep the dies clean from dust and powder residue. A quick wipe with a soft cloth after use is usually sufficient. The seating stem can be occasionally cleaned and lightly lubricated if needed, but this is minimal. There have been no failure points observed, and I expect these dies to last for decades of reloading.

Accessories and Customization Options

This set comes as a complete 3-die package for straight-walled cartridges. It does not typically include additional accessories like different caliber seating stems or specialized crimp inserts, as it’s designed for a specific purpose and caliber group. However, the expander ball on the expander die is usually caliber-specific.

If you were reloading a different straight-walled caliber within the “Group E” designation (like .38 Special, .357 Magnum, etc.), you would likely need a separate die set or potentially a caliber-specific expander plug and seater stem. The dies themselves are not meant for extensive customization beyond adjusting seating depth and crimp. Their strength lies in their dedicated, precise function as provided.
