Hornady Lock-N-Load Iron Press Kit w/Auto Prime Review

What I Wish I Knew Before Buying the Hornady Lock-N-Load Iron Press Kit w/Auto Prime

As someone who has spent over a decade wrestling with gear across labs, workshops, and rugged outdoor environments, I’ve developed a keen sense for what works and what doesn’t. My search for a more robust and efficient reloading press led me to the Hornady Lock-N-Load Iron Press Kit w/Auto Prime. This kit promised a significant upgrade, combining the renowned Lock-N-Load bushing system with an integrated automatic priming system, all housed within a cast iron frame designed for superior strength. I was particularly drawn to the idea of streamlining the reloading process, especially the priming stage, which has always been a point of manual tedium and potential error.

My previous press, while functional, lacked the rigidity and the integrated features I was starting to crave as my reloading volume and standards increased. I had been eyeing presses with similar quick-change bushing systems for a while, but the addition of an automatic primer feeder in a comprehensive kit like this was a compelling proposition. My initial impression upon unboxing was one of solid construction; the cast iron frame felt substantial and well-machined, hinting at the durability Hornady is known for. It certainly felt like a step up from the lighter-weight aluminum or steel presses I’d encountered.

There were a few other contenders in my consideration set. I briefly looked at the RCBS Rock Chucker, a venerable classic, and some progressive presses, but the allure of the Iron Press’s brute strength combined with the convenience of the Lock-N-Load system, plus the all-in-one kit approach, ultimately steered me towards this Hornady offering. My first reaction was a cautious optimism, a feeling that I might have finally found a tool that could genuinely enhance my reloading efficiency and consistency.

Real-World Testing: Putting Hornady Lock-N-Load Iron Press Kit w/Auto Prime to the Test

First Use Experience

My initial testing grounds for the Hornady Lock-N-Load Iron Press Kit w/Auto Prime were my dedicated reloading bench in the workshop. The primary objective was to assemble several batches of rifle cartridges, focusing on consistency and speed. I mounted the press securely, a process that benefited from its substantial weight, which prevented any unwanted movement. My first few pulls of the handle were surprisingly smooth, and the Lock-N-Load bushings lived up to their reputation, making die changes remarkably swift.

The automatic priming system was where I encountered my first significant hurdle. While the concept is brilliant, the execution proved less than flawless. The “Shell Assist Collar,” a key component of the auto-prime mechanism, exhibited a concerning amount of play. This looseness caused the shell casing to tilt forward slightly, leading to misalignments with the priming die and, on more than one occasion, a jammed casing. It was a frustrating start, requiring careful manual manipulation to overcome the inherent wobble.

Furthermore, one of the advertised selling points of the kit was a digital scale. Unfortunately, upon powering it on, I discovered it was completely inoperative. This was a significant disappointment, as a reliable scale is paramount for safe and accurate reloading. Thankfully, Hornady’s customer service was responsive and promptly offered a replacement, but this required an additional delay and hassle, detracting from the initial user experience.

Extended Use & Reliability

After several weeks of consistent use, approximately 500 rounds loaded across different calibers, the Hornady Lock-N-Load Iron Press Kit w/Auto Prime has revealed more about its character. The cast iron frame remains incredibly rigid, providing a stable platform for case resizing and bullet seating, which translates to more consistent dimensions in the finished cartridges. The Lock-N-Load bushings continue to be a major convenience, allowing for rapid caliber changes without the need to readjust dies.

However, the issues with the automatic priming system, specifically the play in the “Shell Assist Collar” (part no. 399606), persist. While I’ve learned to compensate with gentle nudges and precise movements, it’s a constant reminder of a design flaw that detracts from the press’s otherwise robust build. This slight tilt in the casing during the priming cycle is particularly problematic with smaller primers or when loading delicate rounds where precise alignment is critical.

Maintenance is relatively straightforward for the press itself. A light application of lubricant on the ram and pivot points keeps it operating smoothly. The included accessories, aside from the initial scale issue, have held up reasonably well, though the case lube quality is mediocre at best. Compared to some of the lighter, aluminum-framed presses I’ve used in the past, this iron press certainly feels like it can withstand heavy use and the occasional bump without complaint, but the priming mechanism’s play is a persistent concern for long-term reliability.

Breaking Down the Features of Hornady Lock-N-Load Iron Press Kit w/Auto Prime

Specifications

The Hornady Lock-N-Load Iron Press Kit w/Auto Prime is engineered with robust reloading in mind. Its most prominent feature is the Lock-N-Load Bushing System, which allows for extremely fast die changes with its quick-release mechanism. This press boasts a superior strength cast iron frame, giving it a substantial weight of 42 lb, which significantly reduces flex during operation.

Included in this comprehensive kit is a patented Shell Holder Platform, designed to aid in processes like de-priming and chamfering by utilizing natural gravity. The press is also ambidextrous in its operation, catering to both right and left-handed users. Another key specification is the integrated Automatic Priming System, which aims to automate the tedious task of seating primers. An Accessory Deck is also built into the press frame, providing a convenient place to keep small tools and components close at hand.

The kit is surprisingly generous with its included accessories. Beyond the press itself, you receive an Electronic Caliper, a Powder Funnel, several Lock-N-Load Die Bushings, a Lock-N-Load Bullet Comparator Set with six inserts, Hornady’s Reloading Handbook, a Lock-N-Load Powder Measure, a set of Case Prep Accessories, a Digital Scale (though my unit was faulty), a Component Feed Bin & Bracket, a Die Caddy, and a bottle of Unique Case Lube. These additions transform the press into a nearly complete reloading station right out of the box.

Performance & Functionality

In terms of its primary function – resizing, de-priming, and seating bullets – the Hornady Lock-N-Load Iron Press Kit w/Auto Prime performs admirably. The sheer rigidity of the cast iron frame means that even with full-length resizing of tough rifle cases, there’s virtually no noticeable flex or wobble. This translates directly into more consistent case dimensions and straighter bullet seating, which are critical for accurate ammunition. The Lock-N-Load bushings are truly a game-changer for anyone who frequently switches calibers or loads.

However, the Automatic Priming System is where performance falters considerably. The issue lies with the “Shell Assist Collar” (part no. 399606), which exhibits excessive play. This looseness causes the shell casing to tilt forward as it’s raised into position. Consequently, the primer often fails to align perfectly with the priming punch, leading to missed primers, bent primers, or even primers getting stuck in the die. This necessitates manual intervention to ensure proper seating, negating much of the system’s intended automation and speed benefit.

The included accessories add significant value, but their individual performance varies. The Electronic Caliper is precise and handy, and the Reloading Handbook is an invaluable resource for any reloader. The Lock-N-Load Powder Measure is decent for basic volumetric measurements, though for critical accuracy, a more advanced measure or trickler is usually preferred. The primary functional weakness of this kit, by far, is the problematic auto-priming mechanism, which requires careful handling and may even lead some users to abandon it in favor of a separate hand primer.

Design & Ergonomics

The design of the Hornady Lock-N-Load Iron Press Kit w/Auto Prime prioritizes brute strength and functional convenience. The cast iron frame is undoubtedly its most striking feature, giving it an industrial feel and promising long-term durability. The overall finish is a matte black, which is practical and resists showing fingerprints.

Operationally, the press is quite ergonomic, particularly with the Lock-N-Load Bushing System. Swapping dies is as simple as turning a collar, making quick caliber changes a breeze. The large ram handle is comfortable to grip, and its throw is smooth and consistent. The Accessory Deck is a thoughtful addition, providing handy spots for calipers, primers, bullets, and case lube, keeping everything within easy reach.

The main ergonomic drawback, as previously mentioned, stems from the Automatic Priming System. The “Shell Assist Collar” feels slightly unbalanced and wobbly, which not only affects priming but can also make it feel a bit less refined when guiding the case into the shell holder. While the press itself is ambidextrous, the priming system’s slight tilt can require a bit of extra attention regardless of which hand is operating the handle. Despite this, the overall build quality and the intuitive nature of the core press mechanics make it a generally pleasant tool to use, once you navigate the quirks of the priming system.

Durability & Maintenance

Based on its construction, the Hornady Lock-N-Load Iron Press Kit w/Auto Prime appears built to last for decades, if not longer. The heavy cast iron frame is inherently durable and resistant to wear. The ram, being a critical moving part, feels robust and well-supported within its housing. The Lock-N-Load bushings are made of hardened steel and show no signs of wear after hundreds of cycles.

Routine maintenance is minimal. Keeping the ram lubricated with a quality gun oil or general-purpose lubricant will ensure smooth operation. Cleaning is simple; a quick wipe-down with a dry cloth usually suffices, with occasional degreasing if necessary. The primary concern for long-term durability lies not with the press frame itself, but with the plastic components of the Automatic Priming System. The “Shell Assist Collar,” in particular, feels less robust and its inherent play suggests a potential point of failure or increased wear over time compared to the solid metal construction of the press.

Replacement parts for the press frame and ram are likely readily available, given Hornady’s reputation. However, specific components of the auto-prime mechanism might be more niche. For the average reloader performing standard tasks, the press itself should offer exceptional longevity. It’s the delicate auto-priming component that might require more careful handling or eventual replacement.

Accessories and Customization Options

The Hornady Lock-N-Load Iron Press Kit w/Auto Prime comes with a remarkably comprehensive suite of accessories, aiming to provide a complete reloading experience out of the box. The Lock-N-Load Die Bushings are the stars here, enabling lightning-fast die changes and making them a must-have for any serious reloader. The included Lock-N-Load Bullet Comparator Set with six inserts is also a highly useful addition for precisely measuring bullet seating depth.

The Digital Scale and Powder Measure are functional, though as noted, the scale’s initial failure was a significant drawback. The Reloading Handbook is an indispensable reference. The Case Prep Accessories, while basic, cover essential tasks like deburring and chamfering. The Component Feed Bin & Bracket and Die Caddy are practical organizers that help keep the reloading bench tidy and efficient.

Customization for this press is primarily focused on the dies themselves, which are standard 7/8″-14 threaded units compatible with most reloading dies on the market. While the included powder measure is functional, many reloaders opt for more precise digital scales and powder tricklers for critical loads. The automatic priming system is designed as an integrated part of this press, but given its performance issues, users might consider purchasing a high-quality, standalone hand primer for greater reliability and control.

Pros and Cons of Hornady Lock-N-Load Iron Press Kit w/Auto Prime

Who Should Buy Hornady Lock-N-Load Iron Press Kit w/Auto Prime?

The Hornady Lock-N-Load Iron Press Kit w/Auto Prime is ideally suited for intermediate to advanced reloaders who prioritize stability and efficiency in their reloading process. If you frequently switch calibers or are looking for a press that can handle full-length resizing of tough rifle cases without flexing, this iron press is an excellent choice. It’s also a good option for those who appreciate the convenience of the Lock-N-Load Bushing System and are willing to overlook or work around the limitations of the integrated priming system.

However, absolute beginners might find the complexity and the issues with the auto-primer overwhelming. If your sole focus is perfectly reliable and automated priming, you might be better served by a press without an integrated system and a separate, high-quality hand primer. Users who require extremely precise priming for delicate match ammunition might also find the play in the auto-primer’s “Shell Assist Collar” to be a dealbreaker.

For those who purchase this kit, I’d highly recommend investing in a high-quality, separate hand primer for critical applications. Additionally, a more precise powder trickler and a digital powder scale will offer superior accuracy compared to the included measure and scale, especially for precision rifle cartridges. A good quality case lube and resizing lubricant will also enhance the resizing process.

Conclusion on Hornady Lock-N-Load Iron Press Kit w/Auto Prime

The Hornady Lock-N-Load Iron Press Kit w/Auto Prime presents a compelling, albeit flawed, package for the discerning reloader. The press itself, with its cast iron frame and Lock-N-Load Bushing System, is undeniably robust and highly functional, offering the rigidity and speed that many reloaders crave. The comprehensive nature of the kit, including numerous useful accessories, makes it a strong contender for those looking for an all-in-one solution.

However, the significant issues with the integrated Automatic Priming System, specifically the excessive play in the “Shell Assist Collar,” prevent this kit from achieving true excellence. This flaw detracts from the otherwise solid performance and can lead to frustrating inconsistencies in primer seating. While the included accessories are generally good, the initial failure of my digital scale pointed to potential quality control lapses in the ancillary components.

Considering its price point, the Hornady Lock-N-Load Iron Press Kit w/Auto Prime offers a good value for the press and the Lock-N-Load system alone. If you are primarily purchasing it for the press’s strength and the bushing system, and you plan to use a separate hand primer, then this kit is certainly worth considering. For those who absolutely need a flawlessly integrated auto-priming solution, you may need to look elsewhere or be prepared to address the shortcomings of this particular feature. It’s a tool that excels in its core function as a press but falters in one of its advertised convenience features.
