Hornady PTX Powder Measure Stops Review

The One Thing I Didn’t Expect from the Hornady PTX Powder Measure Stops

For over a decade, my reloading bench has been a sanctuary of precision and efficiency, but it’s also been a place where small frustrations can echo. My recent acquisition, the Hornady PTX Powder Measure Stops, wasn’t a purchase driven by a glaring defect, but rather a refinement born from years of incremental learning. It’s a seemingly simple component, a set of small, adjustable mechanical stops designed to augment the case-activated powder drop on my Hornady powder measure. The promise was finer control over case flaring, a detail I hadn’t realized I was compromising on.

The impetus for this upgrade stemmed from a long-standing workaround. For years, I’d been using a single stop, painstakingly set to ensure a full powder throw while also accommodating the varying flare depths required for different pistol calibers. This meant a constant compromise, a delicate dance between a consistent charge and the perfect mouth expansion. More critically, the physical limitations of my press often meant the powder measure was obstructed, limiting how precisely I could adjust that crucial flare depth. It was functional, but far from ideal, and the thought of dedicated adjustments for each caliber began to gnaw at me.

Upon arrival, the Hornady PTX Powder Measure Stops presented themselves with a no-nonsense practicality. Machined metal, precisely threaded, they exuded the kind of robust construction I’ve come to expect from Hornady. There wasn’t any flashy packaging or complex instructions; it was just two small, but significant, pieces of hardware. I briefly considered generic alternatives from other manufacturers, but the integrated nature of my Hornady system made sticking with the same brand a pragmatic choice for guaranteed compatibility. My initial reaction was a quiet sense of anticipation, a feeling that a small, persistent annoyance might finally be laid to rest.

Real-World Testing: Putting Hornady PTX Powder Measure Stops to the Test

First Use Experience

My testing grounds for these stops were strictly within the controlled, yet often demanding, environment of my home reloading workshop. The primary scenario involved setting up for a batch of 9mm Luger and then a separate run of .45 ACP ammunition. This allowed me to directly compare the adjustment capabilities and witness the impact of dedicated stops for each caliber. I performed the initial installations and adjustments on my workbench, ensuring a clean setup before integrating them into the powder measure.

During this initial phase, I subjected the stops to repeated adjustments, cycling the powder drop mechanism numerous times for each caliber. I deliberately varied the settings to push the limits of their adjustability, ensuring they maintained their position without creeping or loosening. The smooth, positive engagement of the adjustment screws provided immediate confidence.

The ease of use was surprisingly intuitive. After a quick look at the basic function, it was clear how to set and lock them down. There was no significant learning curve, just a straightforward application of mechanical adjustment. The only minor surprise was how much finer the adjustment became compared to my old single-stop method; it felt like I suddenly had a much larger dial to work with.

Extended Use & Reliability

After several weeks and the reloading of hundreds of rounds across multiple pistol calibers, the Hornady PTX Powder Measure Stops have proven to be remarkably reliable. They have consistently maintained their set positions, even through repeated cycles of powder dispensing and case insertion. There has been no noticeable slippage or degradation in performance.

Durability-wise, these small components have held up exceptionally well. The machined metal construction shows no signs of wear, even with frequent tightening and loosening of the adjustment screws. I haven’t observed any stiffness developing in the threads, nor any issues with the locking mechanism.

Maintenance and care have been virtually non-existent, which is precisely what you want from a component like this. A quick wipe-down with a dry cloth during routine bench cleaning is all that’s required. There’s nothing to disassemble or complicate the cleaning process. Compared to my previous single-stop setup, which often required re-adjustment if disturbed, these dedicated stops offer a superior level of long-term reliability. The frustration of constantly having to tweak my single setting has been replaced by a confidence in consistent results.

Breaking Down the Features of Hornady PTX Powder Measure Stops

Specifications

The Hornady PTX Powder Measure Stops are a component designed to integrate with the Hornady Case Activated Powder Drop. Each unit is manufactured from machined metal, ensuring a robust and durable build that can withstand the rigors of regular reloading use. The set includes one quantity, implying a single purchase provides the necessary stops for one powder measure setup, though they are often sold in packs or as part of a larger kit.

These stops are designed with top and bottom adjustment screws. This specification is crucial as it allows for a fine-tuning of the flare on cases. In practical terms, this means you can precisely control how much the case mouth is expanded, which is vital for consistent bullet seating and preventing case damage. The $10.49 price point for this upgrade makes it an accessible way to enhance precision in your reloading process.

Performance & Functionality

The primary function of these stops is to enable precise adjustment of the case flare depth during the powder charging process. They excel at this task by providing independent control points that prevent over or under-flaring. This leads to more consistent feeding of bullets into the case mouth and a reduction in rejected rounds due to improperly flared cases.

The main strength of the Hornady PTX Powder Measure Stops lies in their ability to offer dedicated adjustments for each caliber. This is a significant improvement over using a single, compromise setting. They allow for a level of precision that was previously difficult to achieve, particularly when obstructions on the press limited movement. The only potential weakness, if one could call it that, is that they are an add-on component; their effectiveness is still dependent on the overall quality and setup of the powder measure and press they are attached to.

Design & Ergonomics

The design of these stops is rooted in practical functionality. The machined metal construction feels solid and substantial, offering a reassuring tactile experience. Their small size means they integrate seamlessly with the existing powder measure mechanism without adding significant bulk or interfering with other press components.

Ergonomically, the top and bottom adjustment screws are well-placed and easy to manipulate. They offer enough resistance to stay put but are smooth enough for precise, incremental turns. The knurled heads of the screws provide a good grip, even with slightly greasy fingers common in a workshop environment. The overall feel is one of thoughtful engineering focused on user control and reliability.

Durability & Maintenance

Given their machined metal construction, these stops are built for longevity. Under typical reloading conditions, they are unlikely to suffer wear and tear that would impact their performance. The internal threading is robust, and the locking action of the screws is designed to be secure.

Maintenance is exceptionally straightforward; essentially, it involves keeping the threads clean. A quick wipe is usually sufficient. There are no complex parts to clean or lubricate regularly. The potential for failure is extremely low, making them a highly durable addition to any reloading setup.

Accessories and Customization Options

The Hornady PTX Powder Measure Stops are not designed to come with accessories themselves. Instead, they are an accessory that enhances the functionality of existing equipment, specifically the Hornady Case Activated Powder Drop. Their customization lies in their adjustability, allowing the user to dial in specific flare depths for a wide range of calibers. They are designed to work seamlessly with their intended Hornady components, ensuring a precise fit and function.
