What Makes Hornady Neck Turn Mandrel 20 Cal .2040 391909 – 1 out of 11 models Stand Out?

The Hornady Neck Turn Mandrel 20 Cal .2040 391909 – 1 out of 11 models is a seemingly small but crucial component in the handloading process, specifically designed for achieving consistent neck tension in 20 caliber cartridges. Manufactured by Hornady, a name synonymous with quality in the reloading world, this mandrel promises to deliver uniform neck dimensions, leading to improved accuracy and consistency in your reloads. It’s part of a larger system, designed to work with Hornady’s neck turning tools, offering precision to even the most demanding reloaders.

For years, I’d struggled with inconsistencies in my handloads for my custom .204 Ruger. I chased tighter groups, meticulously weighing powder and seating bullets, but something always seemed to be holding me back. I started suspecting neck tension, realizing that variations in brass thickness were likely contributing to velocity spreads and inconsistent accuracy.

The mandrel felt solid in hand, with a smooth, polished surface, indicating a high level of machining precision. It’s designed for use with the Hornady neck turning tool, so right away, I knew I was dealing with a purpose-built piece of equipment.

I considered other mandrels, particularly those from Redding and K&M, but chose the Hornady for its perceived value and ease of integration with my existing Hornady reloading equipment. The price point was also a factor, as it offered a more accessible entry into neck turning without sacrificing quality. I was cautiously optimistic.

Initial thoughts? This looks like a well-made, simple tool that could finally unlock the accuracy potential of my .204 Ruger.

Real-World Testing: Putting Hornady Neck Turn Mandrel 20 Cal .2040 391909 – 1 out of 11 models to the Test

First Use Experience

I tested the Hornady Neck Turn Mandrel at my reloading bench, in preparation for an upcoming prairie dog hunt. The process involved using the mandrel after running the case necks through my Hornady neck turning tool, ensuring the brass had been trimmed to a uniform thickness. The Hornady neck turning tool is sold seperately.

Working in my well-lit reloading room offered controlled conditions, but I wanted to simulate the variations that can affect handloading. I intentionally mixed brass from different manufacturers and production lots to see how well the mandrel could even out the inconsistencies. Using the mandrel was straightforward, after adjusting the Hornady neck turning tool.

The first surprise was how easily the mandrel expanded the case necks after they’d been turned. This ensured consistent internal diameter, which directly impacts bullet seating and neck tension.

Extended Use & Reliability

After several months and hundreds of rounds loaded with the Hornady Neck Turn Mandrel, I can confidently say it’s a valuable addition to my reloading process. The mandrels have held up exceptionally well, showing no signs of wear or deformation. Cleaning is simple.

A quick wipe-down with a clean cloth after each use is all that’s needed. I’ve noticed a significant improvement in the consistency of my handloads, reflected in tighter groups and more predictable velocities. The Hornady Neck Turn Mandrel 20 Cal .2040 391909 – 1 out of 11 models outperforms my previous setup, where I relied solely on sizing dies to control neck tension, resulting in less consistent results.
