Lee Full-Length 3-Die Set Review

The Lee Full-Length 3-Die Set and What It Taught Me

For those of us who delve into the intricate world of reloading, the right tools are not just helpful; they are indispensable. I’ve spent over a decade working with equipment across various demanding environments, from the precision of a laboratory bench to the grit of an outdoor workshop, and I’ve learned that quality and reliability are paramount. That’s why, when I needed to outfit myself for a rather niche reloading endeavor, the Lee Full-Length 3-Die Set for the .577 Nitro Express cartridge presented itself as a compelling option. This set, designed for the classic Martini Henry rifle, promises to bring a significant piece of historical firearm into the modern reloading enthusiast’s hands.

My journey to this particular die set began with the acquisition of a beautifully preserved Martini Henry rifle chambered in .577 Nitro Express. As any collector or shooter of vintage firearms knows, ammunition for such cartridges is often scarce and prohibitively expensive. The only practical path forward was to begin reloading, which immediately presented a challenge: finding a reliable and accessible die set for this large, obsolete caliber. While other, more boutique manufacturers might offer specialized tooling, their price points often placed them out of reach for a project like this. I considered a few custom machining options, but the lead times and cost were simply not feasible for my immediate needs.

Upon receiving the Lee Full-Length 3-Die Set, my initial impression was one of pragmatic solidity. The dies themselves, crafted from steel with a substantial feel, exuded a no-nonsense durability. There wasn’t any flashy presentation; instead, what I saw was a set of tools built for purpose, ready to endure the rigors of reloading. It offered a sense of immediate relief, knowing that a critical piece of the reloading puzzle had finally arrived, and the anticipation of putting it to work was palpable.

Real-World Testing: Putting Lee Full-Length 3-Die Set to the Test

My testing environment for this die set was firmly rooted in a dedicated reloading workshop, a space where precision and repeatability are key. The primary goal was to process spent .577 Nitro Express brass, bringing it back to a state where it could be safely and accurately reloaded for the Martini Henry. This involved sizing the cases to bring them back to spec, seating new bullets, and applying a factory crimp to ensure a secure fit. The workshop conditions were fairly standard, with consistent temperature and humidity, but the task itself demanded accuracy and a certain degree of patience due to the large case dimensions.

First Use Experience

The first experience with this die set was both instructive and surprisingly straightforward. Once the dies were installed in my reloading press, the process of resizing a case felt robust. The full-length sizing die worked effectively, bringing the fired cases back to their original dimensions with a satisfyingly solid action. The bullet seating die also performed admirably, allowing for precise control over bullet depth, which is crucial for both chambering and consistent ballistic performance.

The factory crimp die provided a secure closure to the reloading process, ensuring that the bullet remained firmly seated under recoil. There were no immediate issues or unexpected quirks; the dies performed precisely as their function implied. The inclusion of a shell holder and clear instructions made the initial setup and operation quite intuitive, even for a caliber that is far from commonplace.

Extended Use & Reliability

As I continued to work with the Lee Full-Length 3-Die Set over several reloading sessions, its reliability became increasingly apparent. Processing batch after batch of .577 Nitro Express brass, the dies held their adjustments and continued to produce consistent results. I haven’t noticed any significant wear or tear on the die bodies or their internal components.

The steel construction feels substantial enough to withstand years of use without developing the kind of stiffness or performance degradation I’ve encountered with lesser-quality dies in the past. Cleaning and maintenance are also relatively simple; a quick wipe-down with a rust inhibitor after use is all that’s typically required to keep them in top condition. Compared to some of the more expensive, specialized dies I’ve used for other calibers, this set from Lee offers a performance level that is remarkably close, especially considering the price point.

Breaking Down the Features of Lee Full-Length 3-Die Set

The Lee Full-Length 3-Die Set for the .577 Nitro Express Martini Henry cartridge is a complete package designed to handle the essential stages of reloading this large bore rifle cartridge. It includes the core components necessary to resize, seat bullets, and crimp cases, along with a shell holder to facilitate the process. This comprehensive approach is a hallmark of Lee Precision’s philosophy, aiming to provide accessible tooling for a wide range of firearm calibers.

Specifications

This particular die set is specified for the .577 Nitro Express caliber, which is designed for Rifle type firearms. The large series designation refers to the 1 1/4×12 thread size, common for larger rifle dies, ensuring a sturdy connection to most reloading presses. The set includes a Full Length Sizing Die, a Bullet Seating Die, and a Factory Crimp Die. Also included is the necessary shell holder to properly align the case during resizing and seating.

The importance of these specifications cannot be overstated for this caliber. The 1 1/4×12 thread provides the necessary rigidity to handle the forces involved in sizing a large diameter case like the .577 Nitro Express. The inclusion of a full length sizing die is critical, as it ensures that the entire case is brought back to proper dimensions, making it reliably chamber in the vintage firearm. The bullet seating die allows for precise control over the depth to which the projectile is seated, directly impacting cartridge length and chamber clearance. Finally, the factory crimp die is essential for securing the bullet in place, preventing any setback under recoil or during magazine feeding if applicable.

Performance & Functionality

In its primary function, the Lee Full-Length 3-Die Set performs exceptionally well for reloading .577 Nitro Express ammunition. The full-length sizing die reliably brings fired cases back to specification, making them ready for subsequent steps. The bullet seating die offers good control over seating depth, allowing for consistent cartridge overall length which is vital for reliable feeding and accuracy.

The factory crimp die provides a solid and secure crimp, holding the bullet firmly in place and preventing potential issues. One of the standout strengths of this set is its straightforward functionality; it does exactly what it’s supposed to do without fuss. A minor area where improvement could be seen is in the precision of the seating stem on the bullet seating die, but for this particular application and caliber, it meets and often exceeds expectations, especially considering its accessible price point.

Design & Ergonomics

The design of the Lee Full-Length 3-Die Set is purely utilitarian, focusing on function over aesthetics. The dies are constructed from robust steel, giving them a substantial feel and indicating good durability. The knurled surfaces on the die bodies provide adequate grip for adjustments, though they aren’t overly aggressive.

Ergonomically, once threaded into the press, they operate smoothly. The adjustment collars move with a firm but not overly tight action, staying put once locked down. There’s a slight learning curve for any new die set, but the clear functions of each die—sizing, seating, crimping—make them intuitive to use. The markings on the dies are clear and functional, indicating their purpose.

Durability & Maintenance

Given their all-steel construction, the Lee Full-Length 3-Die Set is built for longevity. I expect these dies to last for many years, even with regular use in reloading .577 Nitro Express cartridges. The materials are resistant to corrosion, provided basic care is taken.

Maintenance is straightforward; a simple wipe-down with a light gun oil or CLP after each session is sufficient to prevent rust and keep the threads clean. There are no obvious potential failure points, assuming standard reloading practices are followed. For instance, over-tightening or forcing cases could damage any die, but the construction of these Lee dies suggests they can handle typical reloading pressures without issue.

Accessories and Customization Options

The Lee Full-Length 3-Die Set comes as a complete set, including the three essential dies and the corresponding shell holder. This means you have nearly everything needed to begin resizing, seating bullets, and crimping your .577 Nitro Express cases. Unlike some premium die sets that might offer interchangeable seating stems or other specialized inserts, this set is designed for a single purpose: to reload this specific cartridge effectively.

While there aren’t extensive customization options for the dies themselves, Lee Precision does offer a range of complementary reloading products that can enhance the overall process, such as their powder measures and presses. The threading on these dies, being a standard 1 1/4×12 thread, ensures compatibility with most common reloading presses on the market. This means that while the dies themselves are specialized for the caliber, they integrate seamlessly into a broader reloading setup.
