RCBS X-Die Small Base Sizer Die Review

From Curiosity to Confidence: My RCBS X-Die Small Base Sizer Die Review

The RCBS X-Die Small Base Sizer Die promises to be a game-changer for reloaders, offering the allure of eliminating repeated case trimming. RCBS, a name synonymous with quality reloading equipment, aims to simplify the bottleneck case resizing process with this innovative die. My experience with reloading spans over a decade, and the tediousness of trimming cases is a constant battle.

What drew me to the RCBS X-Die Small Base Sizer Die was the promise of “trim once, never trim again.” The constant measuring and trimming of my .223 Remington cases was eating into my reloading time. If this die could genuinely deliver on its claim, it would be a substantial time-saver.

Upon opening the package, the die appeared well-machined and robust, befitting the RCBS reputation. The steel construction felt solid, and the silver finish was clean and professional. Its design seemed straightforward, but the specialized mandrel and expander ball hinted at the intricate mechanics within.

I considered other resizing dies, including standard small base sizers from RCBS and Redding. However, the unique case-length control mechanism of the X-Die swayed my decision. I was willing to invest a bit more upfront for the potential long-term time savings and improved case consistency. My initial impression was one of cautious optimism; the concept was intriguing, and I was eager to see if the X-Die lived up to the hype.

Real-World Testing: Putting RCBS X-Die Small Base Sizer Die to the Test

First Use Experience

My first test with the RCBS X-Die Small Base Sizer Die took place in my reloading workshop. I was resizing .223 Remington cases that had been previously fired from my AR-15. I wanted to see how it would perform with a batch of brass that had already experienced some expansion and work hardening.

The die was straightforward to set up, following the instructions provided by RCBS. I initially trimmed all cases to 0.020″ below the maximum case length. I resized approximately 50 cases. The resizing process itself felt smooth and consistent, with no excessive force required.

The most noticeable aspect was the lack of case lengthening after resizing. Standard resizing dies often stretch the case neck, necessitating trimming. I monitored case lengths after each resizing and found minimal changes. No immediate problems arose, but I needed more rounds to test stability.

Extended Use & Reliability

After several weeks of using the RCBS X-Die Small Base Sizer Die, I have resized hundreds of .223 Remington cases. The die continues to perform consistently. I’ve encountered no failures or malfunctions.

There’s been minimal wear and tear on the die itself. I maintain it by cleaning and lubricating it after each reloading session. Compared to my experience with standard resizing dies, the X-Die has significantly reduced the need for case trimming. My reloading sessions are now more efficient, and I have more confidence in the uniformity of my cases.

Breaking Down the Features of RCBS X-Die Small Base Sizer Die

Specifications

The RCBS X-Die Small Base Sizer Die is constructed from durable steel with a silver finish. It is designed specifically for bottleneck rifle cartridges. The “Small Base” designation indicates that it sizes the case body slightly more than a standard die. This is important for reliable feeding in semi-automatic rifles like the AR-15. The key features include a specially designed mandrel with an expander ball and decapping pin attached. The die’s patented design allows for maintaining consistent case lengths, theoretically eliminating the need for repeated trimming after the initial setup.

These specifications are crucial for reloaders seeking accuracy and reliability, especially in semi-automatic rifles. The small base sizing ensures proper chambering, while the case-length control simplifies the reloading process and improves consistency.

Performance & Functionality

The RCBS X-Die Small Base Sizer Die performs its primary function – resizing bottleneck cases – exceptionally well. It maintains consistent case lengths, reducing the need for trimming. The initial trimming is still essential, but after that, cases tend to stabilize within a narrow length range.

The die’s strengths lie in its ability to streamline the reloading process and promote case-length uniformity. A potential weakness is that it requires precise initial trimming to function correctly. I found that the X-Die exceeded my expectations.

Design & Ergonomics

The RCBS X-Die Small Base Sizer Die is a well-built piece of reloading equipment. The steel construction feels robust. Its ergonomics are typical of resizing dies. It is easy to install and adjust in a reloading press.

The die is user-friendly, although a clear understanding of bottleneck case resizing is beneficial. It requires no special tools or techniques beyond those used for standard resizing dies.

Durability & Maintenance

Given its steel construction, the RCBS X-Die Small Base Sizer Die should last for many years with proper care. I expect to get a lifetime of use out of it.

Maintenance involves cleaning the die with a solvent and lubricating it periodically with a reloading die lubricant. This process is straightforward and takes only a few minutes.

Accessories and Customization Options

The RCBS X-Die Small Base Sizer Die comes as a standalone die. To complete the reloading process, it needs to be paired with a seating die. RCBS offers a standard seating die separately or in a set with the X-Die. The die is compatible with standard reloading presses and shell holders. There are no specific customization options for the die itself, but reloaders can adjust the resizing depth to fine-tune case dimensions.

Pros and Cons of RCBS X-Die Small Base Sizer Die

Who Should Buy RCBS X-Die Small Base Sizer Die?

The RCBS X-Die Small Base Sizer Die is perfect for reloaders who reload bottleneck rifle cartridges, especially .223 Remington or 308 Winchester, and who value efficiency and consistency. It is a great choice for those who primarily shoot semi-automatic rifles like AR-15s, where reliable feeding is critical. It is ideal for high-volume reloaders who want to minimize the tedious task of case trimming.

This product may not be necessary for reloaders who only load a small number of rounds or who meticulously trim each case to a precise length. It’s also less relevant for straight-walled cartridges.

A must-have accessory is a high-quality case trimmer for the initial trimming process. A case gauge is also useful for verifying proper case dimensions.

Conclusion on RCBS X-Die Small Base Sizer Die

The RCBS X-Die Small Base Sizer Die is a worthwhile investment for reloaders seeking to streamline their bottleneck case resizing process. It genuinely reduces the need for repeated case trimming, saving time and improving consistency. The small base sizing enhances reliability in semi-automatic rifles, making it a particularly good choice for AR-15 owners.

The price of $50.49 is justified by the time savings and improved accuracy potential. I personally recommend the RCBS X-Die Small Base Sizer Die to any serious reloader looking to optimize their process. If you’re tired of trimming cases, this die is a game-changer. Consider adding the RCBS X-Die Small Base Sizer Die to your reloading bench and experience the convenience of “trim once, never trim again!”
