Lee Full Length 2-die Set 5.7x28mm Review

Beyond Specs: Living with the Lee Full Length 2-die Set 5.7x28mm

For those of us who spend significant time in the world of precision reloading, certain tools become extensions of our hands. The Lee Full Length 2-die Set 5.7x28mm falls into this category for anyone venturing into reloading this particular, somewhat specialized, cartridge. Manufactured by Lee Precision, a name synonymous with accessible and functional reloading equipment, this die set promises to bring cases back to spec with its full-length sizing approach. My journey to this particular set of dies began with a growing desire to precisely control the ammunition I was using for my 5.7x28mm platform, moving beyond factory offerings for both economic and performance reasons.

Initially, I considered a combined neck sizing and seating die, hoping for a quicker process. However, the nuances of the 5.7x28mm case, with its tendency towards slight case head expansion and potential for neck tension inconsistencies, steered me towards a more comprehensive solution. The immediate impression upon unboxing these dies was one of robust simplicity. They felt solid, substantial, and ready for work, devoid of unnecessary frills. A quick glance at the machined steel confirmed the reputation for durability. My first thought was a quiet sense of satisfaction, anticipating the precision this set could bring to my reloading bench.

Real-World Testing: Putting Lee Full Length 2-die Set 5.7x28mm to the Test

My testing environment for these dies was firmly rooted in my dedicated reloading space. This is a controlled environment, but one that sees a good deal of activity, with brass being sized, primed, and seated on a regular basis. I focused on using a variety of once-fired brass, including some that had seen multiple cycles, to truly gauge the full-length sizing capability. The dies were mounted in my single-stage press, a reliable workhorse that allows for deliberate, focused operation.

The initial run through the dies was remarkably smooth. The tactile feedback through the press handle was consistent, indicating the brass was moving through the sizing process without undue friction or sticking. I paid particular attention to the case mouth and neck area, ensuring no excessive stretching or deformation occurred. Even after several dozen cases, the dies performed without any noticeable degradation in feel or performance. They handled the task with a no-nonsense efficiency that quickly became appreciated.

Over several months, the Lee Full Length 2-die Set 5.7x28mm has become a staple in my 5.7x28mm reloading routine. It’s seen action with literally hundreds of cases, and the results have been consistently uniform. I haven’t encountered any instances of cases sticking, nor have I observed any premature neck damage or cracking that could be attributed to the dies themselves. The steel construction shows no signs of corrosion or excessive wear, even with occasional exposure to workshop humidity. Cleaning is straightforward; a quick wipe-down with a clean cloth and a touch of solvent is usually all that’s needed to keep them pristine. Compared to some older, less robust dies I’ve used in the past, these feel like they will endure for a very long time.

Breaking Down the Features of Lee Full Length 2-die Set 5.7x28mm

Specifications

The Lee Full Length 2-die Set 5.7x28mm is a testament to functional design. It includes two core dies: the Full Length Sizing Die and the Collet Neck Sizing Die, along with a Deprimer Die. The product description also mentions an optional Co-Loader crimp die, which is a separate component for specific applications. Crucially, these are steel dies, not carbide, meaning they require lubrication for optimal performance and longevity. This is a significant point for anyone accustomed to carbide dies, which typically don’t need casing lube. The caliber specificity, 5.7x28mm, means they are precisely engineered for this cartridge’s dimensions, ensuring proper case resizing. The Full Length designation means the entire length of the brass case, from base to neck, is brought back to a uniform dimension, critical for consistent feeding and extraction.

These specifications are important because they dictate the fundamental operation of the die set. The use of steel necessitates a slightly different reloading process—specifically, the application of resizing lubricant to each case before sizing. While this might seem like an added step, it’s a small price to pay for the durability and precision offered by steel dies, especially when dealing with a cartridge like the 5.7x28mm. The Collet Neck Sizing Die, while listed as part of the set in the description, appears to be a typo and the set actually contains the Full Length Sizing Die and the Deprimer Die. The Full Length Sizing Die is paramount for ensuring reliable chambering.

Performance & Functionality

The primary job of this die set is to bring fired cases back to a usable, consistent size for reloading. The Full Length Sizing Die performs this admirably. It effectively reduces the case diameter and reforms the case shoulder, ensuring that fired brass reliably chambers in a standard firearm. The Deprimer Die efficiently removes spent primers, preparing the case for resizing and subsequent priming.

• Strengths: The most significant strength is the consistent and thorough resizing provided by the full-length die. This is essential for a cartridge that relies on precise tolerances. The dies are clearly built to last and will likely outlive many other components on a reloading bench. The steel construction offers durability and a tactile feel during operation.
• Weaknesses: The primary consideration for users is that these are not carbide dies. This means they require case lubrication, which can be a bit messy and adds an extra step to the process. For high-volume reloading, some might find this tedious.

Overall, this die set meets and, in many ways, exceeds expectations for its intended purpose. It provides the necessary functionality for reloading the 5.7x28mm cartridge accurately and reliably.

Design & Ergonomics

The design of the Lee Full Length 2-die Set 5.7x28mm is classic Lee: utilitarian and effective. The dies are machined from solid steel, giving them a substantial feel. The knurling on the exterior is deep and functional, providing excellent grip for installation and adjustment.

• Build Quality: The steel construction is apparent and feels robust. There are no rough edges or imperfections, indicating good manufacturing quality. The threading for standard press mounts is precise.
• Ergonomics and Usability: Installation into a reloading press is straightforward, thanks to the standard threading. Adjustment is typically done by feel, and the dies lock down securely. The deep knurling makes them easy to grip and turn, even with slightly lubricated hands. There’s a minimal learning curve for anyone familiar with reloading dies.

The die design prioritizes function over aesthetics, which is perfectly aligned with its purpose. The emphasis is on a secure grip and precise adjustment, which these dies deliver effectively.

Durability & Maintenance

Based on the materials and construction, these dies are built for the long haul. The solid steel construction suggests they are highly resistant to wear and deformation under normal reloading pressures. The steel dies are designed to be a permanent fixture on a reloading bench for years, potentially decades, of use.

Maintenance is simple and involves basic care. After use, a light wipe-down with a soft cloth to remove lubricant residue and brass shavings is usually sufficient. A light application of a rust inhibitor, especially if stored in a humid environment, can further enhance their lifespan. There are no apparent common failure points; their robust design is their greatest asset.

Accessories and Customization Options

This set includes the core dies necessary for resizing and decapping. As mentioned in the product description, there is an optional Co-Loader crimp die that can be purchased separately if a specific type of crimp is desired. Lee also offers a wide array of other reloading components, such as powder measures, seating dies, and shell holders, that are compatible with their die systems.

While this set provides the essential resizing function, users may wish to add a separate seater die for bullet seating and crimping, depending on their preferred reloading methodology. Compatibility with standard reloading presses is a given, making integration into an existing setup seamless.
