Let’s Dive into RCBS X-Die Small Base Sizer Die
For years, I’ve chased the elusive dream of consistent, perfectly sized rifle cartridges. The RCBS X-Die Small Base Sizer Die promises just that – a way to trim cases once and never again. It’s a bold claim, but one that immediately piqued my interest, given my extensive reloading experience and the meticulous nature required for precision ammunition.
Case trimming, a necessary evil for bottleneck cartridges, can be tedious and time-consuming. I was specifically looking for a solution to improve the consistency of my .223 reloads for AR-15 platform rifles, both for competitive shooting and varmint hunting.
Upon unboxing the die, I was immediately struck by its robust construction. The steel felt solid and well-machined, what I expect from RCBS. The mandrel design, with its integrated expander ball and decapping pin, looked innovative and efficient, I could see the engineering that went into it.
I considered several other sizing dies, including standard small base dies from RCBS and Redding, but the “no more trimming” promise of the RCBS X-Die Small Base Sizer Die swayed me. Ultimately, the time saved and the promise of greater consistency made it the most appealing option.
My first impression was one of cautious optimism. I was excited to see if it lived up to the hype, but also a bit skeptical of any “one-size-fits-all” solution in the precise world of reloading. I couldn’t wait to get to my reloading press and begin using it, the anticipation was killing me.
Real-World Testing: Putting RCBS X-Die Small Base Sizer Die to the Test
First Use Experience
My first test of the RCBS X-Die Small Base Sizer Die took place in my well-equipped reloading room. I was preparing .223 Remington ammunition for an upcoming prairie dog hunt. I processed approximately 100 cases of mixed headstamps, previously fired in my AR-15.
The die functioned smoothly, with the expander ball providing consistent neck tension. I immediately liked the built in decapping pin as it saved a step in my process. However, I did encounter slightly more resistance than with a standard sizing die, likely due to the small base design and mandrel.
I didn’t run into any issues during the first use, but I noticed the cases grew a very small amount after firing. This was expected, but needed to be closely monitored to ensure reliability.
Extended Use & Reliability
After several months of using the RCBS X-Die Small Base Sizer Die, I can confidently say it has significantly streamlined my reloading process. I’ve reloaded several hundred rounds through it, and the initial batch I trimmed has remained within spec. I have experienced less brass waste, which is a big plus.
The die itself shows no signs of wear and tear. The steel construction seems very durable, even after repeated use.
Cleaning is straightforward, requiring only occasional lubrication. Compared to my previous process, which involved frequent case trimming, this die has been a game-changer. I can tell that my rounds are more consistent when shooting.

Performance & Functionality
The RCBS X-Die Small Base Sizer Die performs its primary function – resizing bottleneck rifle cartridges – exceptionally well. It resizes the cases to near minimum SAAMI specifications, ensuring reliable feeding and chambering, particularly important in semi-automatic rifles like the AR-15. The consistency of neck tension achieved with the expander ball contributes to improved accuracy.
However, it’s crucial to follow the instructions carefully, especially regarding the initial case trimming. Cases that are too long can cause damage to the die. While the “no more trimming” claim is largely true, it’s essential to monitor case length periodically, especially with high-pressure loads.
Design & Ergonomics
The die is well-machined and easy to install in any standard reloading press. The integrated mandrel design simplifies the process, but the slightly increased resizing force might require more leverage.
The steel construction feels robust and durable. The design is straightforward and functional, prioritizing performance over aesthetics.
Durability & Maintenance
The RCBS X-Die Small Base Sizer Die is built to last. With proper care and lubrication, it should provide years of reliable service.
