Let’s Dive into RCBS X Mandrel Assy
The RCBS X Mandrel Assy is a seemingly small but crucial component for reloaders seeking consistent and accurate ammunition, particularly for .223 Remington. Manufactured by RCBS, a name synonymous with quality reloading equipment, this assembly plays a pivotal role in case preparation. It’s designed to work in conjunction with the X-Die Sizer to de-prime cases and expand the neck, ensuring proper bullet seating and consistent neck tension.
What led me to this product was a quest for improved consistency in my .223 reloads. I was experiencing inconsistent neck tension, leading to variations in velocity and accuracy. I wanted a solution that would allow me to minimize runout.
Upon receiving the RCBS X Mandrel Assy, I immediately noted its simple yet robust design. The steel construction felt solid, suggesting durability. My initial thoughts were it may reduce bullet runout during seating.
While there are other expander mandrels on the market, such as those from Lee Precision and Hornady, I chose the RCBS X Mandrel Assy because of its specific compatibility with the RCBS X-Die Sizer. I had heard reports on its potential to improve the consistency of neck tension. My first impression was cautiously optimistic. This seemed like a well-made tool, but the proof would be in its performance.
Real-World Testing: Putting RCBS X Mandrel Assy to the Test
First Use Experience
My initial testing of the RCBS X Mandrel Assy took place at my reloading bench, focusing on preparing .223 Remington cases for precision rifle shooting. I paired it with the RCBS X-Die Sizer as intended and processed a batch of 100 cases. The consistent neck expansion achieved was immediately noticeable.
I tested the assembly over the course of several hours, noting its performance when the cases were wet from lubricant. It performed flawlessly under those conditions. The ease of use was also apparent; it was a simple drop-in replacement for the standard expander. There were no issues or surprises after the first use.
Extended Use & Reliability
After several months of consistent use, the RCBS X Mandrel Assy has held up remarkably well. There are no signs of significant wear and tear. This speaks to the quality of the steel used in its construction.
Maintenance is straightforward. After each reloading session, I wipe down the expander rod and decapping pin with a lightly oiled cloth. This keeps them clean and prevents corrosion. Compared to my previous experience using a standard expander button, the RCBS X Mandrel Assy provides significantly more consistent neck tension. It has noticeably improved the accuracy of my reloads.
