Let’s Dive into Lyman Universal Priming Arm for T-Mag & Crusher Presses
The Lyman Universal Priming Arm for T-Mag & Crusher Presses is a seemingly small component that makes a huge difference in the reloading process. This isn’t just another piece of metal; it’s the heart of consistent primer seating, and anyone who reloads knows that consistent primer seating is crucial for consistent ammunition. It replaces the priming arm on Lyman’s T-Mag and Crusher presses, and it promises to seat all sizes and types of primers with ease.
For years, I wrestled with inconsistent primer seating using the original priming arm that came with my Lyman T-Mag. I was plagued with primers that were either slightly crushed or not seated deeply enough, resulting in inconsistent ignition and accuracy issues. After countless hours of frustration and wasted components, I decided to seek a solution, landing on the Lyman Universal Priming Arm for T-Mag & Crusher Presses.
Upon unboxing, I was immediately struck by the solid feel of the arm. The Aluminum and Steel construction inspired confidence. It felt significantly more robust than the original priming arm. The two included priming sleeves (large and small) were neatly packaged. My initial thought was, “Finally, a priming system that might actually work!”
I had also considered the RCBS Automatic Priming Tool, but I liked the idea of keeping the priming process integrated with my press for space-saving and workflow reasons. I also briefly looked at the Hornady priming system, but opted to stay within the Lyman ecosystem. This choice boiled down to my existing comfort with the Lyman press and positive user reviews regarding the Lyman Universal Priming Arm for T-Mag & Crusher Presses.
My first impression was definitely one of cautious optimism. I was excited to see if it would live up to its claims of universal compatibility and consistent seating depth. However, I was also wary, having been burned by other “universal” products in the past. The build quality gave me hope, though.
Real-World Testing: Putting Lyman Universal Priming Arm for T-Mag & Crusher Presses to the Test
First Use Experience
My initial test was conducted at my reloading bench, a converted section of my garage meticulously organized to maximize efficiency. I primarily reload for my .308 Winchester and 9mm pistols. I planned to load 50 rounds of each. I tested the Lyman Universal Priming Arm for T-Mag & Crusher Presses using both CCI and Federal primers.
The arm performed admirably under normal conditions. The primer seating was much smoother and more consistent than with the original arm. However, when I attempted to seat primers in some slightly crimped military brass, the arm showed a bit of flex. It wasn’t a failure, but it required more force than I was comfortable with.
The most significant challenge was the changing between primer sizes. I realized very quickly I’d want to own more than one arm. Switching the priming sleeves involves removing a small retaining clip, swapping the sleeve, and re-attaching the clip. It’s not difficult, but it’s certainly not quick, especially when switching between small and large primers frequently. I definitely see the merit in the user feedback that suggested keeping one arm dedicated to each primer size.
Extended Use & Reliability
After several months of regular use, the Lyman Universal Priming Arm for T-Mag & Crusher Presses has proven to be a worthwhile upgrade. I’ve loaded thousands of rounds using it. The primer seating is consistently more uniform, leading to improved accuracy and fewer misfires.
The arm has held up well, showing no signs of significant wear and tear. The Aluminum and Steel construction has proven durable. I have, however, noticed that the retaining clip for the priming sleeves can become slightly loose over time. I addressed this by applying a small amount of Loctite to the clip, which seems to have solved the issue.
Maintenance is relatively simple. A quick wipe-down with a clean cloth after each reloading session is usually sufficient. I also occasionally apply a light coat of oil to the moving parts to ensure smooth operation. Comparing it to my previous experience with the original priming arm, the Lyman Universal Priming Arm for T-Mag & Crusher Presses is a definite improvement in consistency and ease of use. The primer seating is noticeably smoother and more reliable.
