Is the Hype Real? Hornady Lock-N-Load Modified Cases .17 Hornet Reviewed
For those deeply invested in precision reloading, especially for finicky cartridges like the .17 Hornet, the quest for perfect alignment is never-ending. My journey led me to the Hornady Lock-N-Load Modified Cases .17 Hornet, a product specifically designed to address a critical aspect of reloading accuracy. As an equipment specialist with over a decade of experience across diverse environments, I’ve come to appreciate how small details can dramatically impact results. This particular set of modified cases from Hornady promised a solution to ensure consistent seating of projectiles, a common bottleneck for achieving sub-MOA accuracy. I’d been wrestling with slightly inconsistent neck runout on my standard .17 Hornet cases, and the promise of a perfectly square and precisely aligned seating surface was too compelling to ignore. While I briefly considered attempting to modify my own brass, the time investment and the risk of error made purchasing these specialized cases a more practical choice. My initial impression upon handling them was positive; the machined quality felt precise, and the material seemed robust.
Real-World Testing: Putting Hornady Lock-N-Load Modified Cases .17 Hornet to the Test
First Use Experience
My testing ground for these modified cases was my dedicated reloading bench, a space that sees constant use and can get quite dusty. I primarily integrated them into my load development process for a custom .17 Hornet rifle, where minute accuracy gains are crucial. I specifically aimed to replicate conditions that might stress case alignment, such as loading a batch of 50 rounds consecutively without any breaks.
The ease of use was immediately apparent. The fine threading for the Lock-N-Load system engaged smoothly, and the cases seated perfectly square with the gauge. There was no discernible wobble or play, which is precisely what you want when measuring headspace or bullet runout.
One minor surprise was how effortlessly standard .17 Hornet bullets slipped into the precisely reamed necks. It confirmed the specification about the slight opening, allowing for easy, yet concentric, insertion.
Extended Use & Reliability
After several weeks of consistent use, involving the reloading of over 150 rounds for various load development experiments, these modified cases have held up remarkably well. I’ve subjected them to repeated seating and unseating within the Lock-N-Load precision gauges, and they show no signs of thread wear or deformation.
The durability of the machined brass is evident; they have maintained their precise dimensions. Unlike some standard brass that can develop slight variations in neck tension or roundness after multiple firings and resizing cycles, these modified cases are designed for a specific purpose and seem to excel at it.
Maintenance has been minimal. A quick wipe-down with a soft cloth after use is usually sufficient. I haven’t encountered any issues with stiff threads or the need for specialized cleaning beyond what’s typical for brass cases.
Compared to my previous experiences with standard, unmodified brass for high-precision applications, these cases offer a significant advantage. They eliminate a potential variable that could otherwise lead to frustrating inconsistencies in group size. While premium reloading dies and precise measuring tools are essential, having perfectly modified cases like these elevates the entire process.
Breaking Down the Features of Hornady Lock-N-Load Modified Cases .17 Hornet
Specifications
The Hornady Lock-N-Load Modified Cases .17 Hornet are engineered with two primary modifications for enhanced precision reloading. First, they feature a special fine thread, specifically designed to mate with Hornady’s Lock-N-Load Precision Gauges. This ensures the case remains perfectly square when attached, critical for accurate headspace measurements.
Secondly, the neck of the case is meticulously made perfectly round and opened slightly. This modification allows a standard diameter bullet to slip into the case mouth effortlessly, yet concentrically, promoting the most precise bullet seating possible. The caliber itself, .17 Hornet, demands high accuracy, and these modifications directly address that need by minimizing variables.
Performance & Functionality
In their intended role with the Lock-N-Load Precision Gauges, these modified cases perform exceptionally well. Their primary function is to provide a stable, perfectly aligned platform for measurement and alignment. When used for bullet seating in conjunction with a precision seating die, the concentric neck opening greatly aids in achieving minimal bullet runout.
The main job of these cases is to eliminate case-related runout issues during the reloading process. They succeed admirably, providing a consistent and repeatable starting point for accurate cartridge assembly. The key strength lies in their precise machining and the specific modifications that directly combat common sources of error in precision reloading.
Design & Ergonomics
The design of these cases is purely functional, focused on precision. The fine thread is robust and engages smoothly with the corresponding gauge threads. The overall feel is one of quality craftsmanship, indicative of Hornady‘s commitment to producing reliable reloading components.
The ergonomic aspect is less about handling and more about how they integrate into the reloading workflow. Their design makes them easy to pick up and thread into the gauge, and their uniform dimensions prevent any fumbling or misalignment during setup. The slightly opened neck is a thoughtful touch that simplifies bullet insertion without compromising concentricity.
Durability & Maintenance
These modified cases are designed for longevity within the scope of their intended use. They are not intended for repeated firing cycles like standard reloading brass. Instead, their durability is measured by their ability to withstand repeated attachment and detachment from precision gauges and their consistent dimensional integrity.
Maintaining them is straightforward. A clean environment and occasional gentle wiping are all that’s needed. The fine threads are less prone to damage from dirt ingress than coarser threads, but it’s still good practice to keep them clean. Potential failure points would likely be related to cross-threading or physical damage, rather than wear and tear from normal use.
Accessories and Customization Options
These Hornady Lock-N-Load Modified Cases .17 Hornet are designed to work specifically with the Hornady Lock-N-Load Precision Gauges. They are essentially a precision accessory in themselves, rather than something that comes with many external accessories.
While there isn’t direct customization of the case itself, its purpose is to facilitate customization of your reloaded ammunition. The modification ensures that when you use your preferred precision seating die, the bullet is seated as concentrically as possible, allowing for the most precise adjustments to your final ammunition specifications.
