What Makes the Hornady Zip Spindle Dies Conversion Kit Click?
As a reloading enthusiast with a focus on precision and efficiency, I’m always on the lookout for ways to streamline my process. My workshop is a testament to years of hands-on experience, filled with tools that have seen everything from delicate calibration work to the rough and tumble of high-volume reloading sessions. I recently found myself needing a small but significant upgrade to my existing sizing dies, which led me to the Hornady Zip Spindle Dies Conversion Kit.
This kit is designed to bring Hornady’s innovative “Zip Spindle” design to their New Dimension sizing dies. The core issue I faced was the time and occasional fumbling required to adjust my older dies for different bullet seating depths or neck tensions. I considered other brands of dies entirely, but the cost and the need to re-verify my existing dies’ performance made that a less appealing option. The appeal of a simple conversion, offering a tangible improvement without a complete overhaul, was undeniable. My initial impression upon holding the kit was one of solid, no-nonsense functionality; the components felt well-machined and ready for duty.
Real-World Testing: Putting Hornady Zip Spindle Dies Conversion Kit to the Test
First Use Experience
My testing grounds were my own reloading bench, a space meticulously organized for consistent results. I installed the Hornady Zip Spindle Dies Conversion Kit on a standard Hornady New Dimension sizing die. The process was straightforward, taking less than five minutes from opening the package to having it installed and ready for adjustment.
The primary test involved adjusting the die for various shoulder set-back measurements across a few rifle cartridges. The difference was immediately apparent; the threaded spindle allowed for much finer, more tactile adjustments than the older friction-fit collar. I experienced no binding or slippage, even when making minute changes.
Extended Use & Reliability
After several weeks of consistent use, processing dozens of brass cases, the performance of this small conversion kit has been remarkably consistent. The threaded spindle and collet maintain their grip without any signs of loosening or degradation. Adjustments remain smooth and precise, eliminating the guesswork I sometimes encountered with the previous design.
Cleaning is as simple as wiping down the die components. The metal finish shows no signs of corrosion or premature wear, even with occasional exposure to oils and cleaning solvents. Compared to my older dies, which required more deliberate force and occasionally marked the die body, this conversion feels like a significant step up in user experience and longevity.
Breaking Down the Features of Hornady Zip Spindle Dies Conversion Kit
Specifications
The Hornady Zip Spindle Dies Conversion Kit is a simple, two-piece upgrade. It includes one threaded spindle and one threaded spindle collet. These are made from what feels like hardened steel, offering excellent durability for the intended use.
The purpose of these components is to replace the standard spindle mechanism on Hornady New Dimension sizing dies. This conversion allows for rapid, secure, and repeatable adjustments to the die’s depth. This is crucial for reloaders who frequently switch between different bullet types or desired neck tensions within the same caliber.
Performance & Functionality
The main job of this kit is to enhance the adjustability of a sizing die, and it performs this task exceptionally well. The ability to quickly lock down a precise setting is invaluable for maintaining consistency between reloads. This directly translates to more accurate and reliable ammunition.
Its primary strength is the instantaneous and secure adjustment it provides. There are no real weaknesses to speak of in its intended function; it does precisely what it’s designed to do, and it does it effectively. It certainly meets, and in terms of adjustability and speed, exceeds the capabilities of a standard non-threaded spindle.
Design & Ergonomics
The design is pure functionality. The components are precisely machined to fit standard Hornady dies, ensuring a snug and secure fit. The knurling on the spindle provides a good grip, allowing for fine adjustments even with slightly greasy fingers.
The ergonomics are superior to the older friction-collar designs. The threaded spindle collet allows for a firm lock-down, preventing any accidental shifts during the resizing process. This tactile feedback and secure locking mechanism significantly improve the overall user experience at the reloading bench.
Durability & Maintenance
Given the robust materials, the Hornady Zip Spindle Dies Conversion Kit is built for the long haul. It’s designed for a lifetime of use in typical reloading environments. Maintenance is minimal, essentially boiling down to keeping the threads clean and occasionally applying a light lubricant.
There are no obvious failure points. As long as the threads are kept free of debris, this kit should perform flawlessly for years. It’s a testament to Hornady‘s commitment to producing reliable reloading components.
Accessories and Customization Options
This is a direct conversion kit, meaning it doesn’t come with additional accessories in the traditional sense. Its purpose is to enhance an existing die, not to expand its functionality with new tools. There are no external customization options, as it’s designed to integrate seamlessly with specific Hornady dies.
