Lee Collet 2-die Set .50bmg Review

Let Me Tell You About the Lee Collet 2-die Set .50bmg

For those deeply invested in the world of precision handloading, particularly for magnum rifle calibers, the pursuit of optimal accuracy often leads down a specific path. My own journey with large-caliber reloading, specifically the .50 BMG, presented a recurring challenge: achieving consistent neck tension without excessive case stretching or distortion. It was this very need that drove me to seek out a specialized solution, and eventually, my attention landed on the Lee Collet 2-die Set .50bmg.

This set represents a specialized approach to neck sizing, eschewing the more traditional methods for a collet-based system. I’d heard whispers about its effectiveness, particularly for magnum cartridges where case integrity is paramount. While I had other reloading dies in my extensive arsenal, none were tailored specifically for the .50 BMG in this manner.

Upon arrival, the initial impression was one of utilitarian ruggedness, typical of Lee products. The dies felt substantial, with a reassuring heft that spoke of solid metal construction. There was no unnecessary embellishment, just a clear indication of their purpose. I had considered other, more expensive, custom die sets, but for a .50 BMG setup, the practicality and known efficacy of Lee’s collet system made this an obvious starting point. My first reaction was a quiet sense of anticipation, a feeling that this tool might just solve a long-standing reloading puzzle.

Real-World Testing: Putting Lee Collet 2-die Set .50bmg to the Test

First Use Experience

My initial testing of this neck sizing die set took place on my reloading bench, a space that has seen countless rounds of ammunition come to life. The environment is a controlled workshop, where precision is key, and dust is kept to a minimum. I was working with previously fired .50 BMG brass, aiming to restore the neck tension to optimal levels for re-seating projectiles.

The process was surprisingly straightforward, though it’s important to note that this particular die set is designed for use only with the Lee Classic Cast Press. This is a critical detail that would prevent its use with other press brands, a limitation to be aware of. The collet die itself required minimal adjustment to achieve the desired neck tension, a welcome change from some other dies that can be finicky.

There were no immediate issues, but I did notice that the set does not include a shell holder or powder dipper, which are essential for completing the reloading process. This is typical for die sets but worth reiterating for absolute beginners.

Extended Use & Reliability

After weeks of regular use, meticulously reloading .50 BMG cartridges for extended range sessions, the Lee Collet 2-die Set .50bmg has proven its mettle. It has held up exceptionally well, with no visible signs of wear or performance degradation on the critical collet surfaces. The die bodies remain true, and the resizing action remains consistent, round after round.

Maintenance has been minimal, primarily involving a light wipe-down with a soft cloth after use and a touch of lubricant on the threads occasionally. Compared to full-length resizing dies that can work harden cases over time, this collet-style die offers a distinct advantage in preserving case life. The brass necks retain their integrity, and I’ve noticed a significant reduction in case neck runout, which is crucial for consistent ignition and accuracy in this powerful cartridge.

It has certainly performed better than some older, generic neck sizing dies I’ve used in smaller calibers, which sometimes struggled with consistency or could even lead to case head separation if not carefully monitored. This set feels built for the task, offering reliability that inspires confidence.

Breaking Down the Features of Lee Collet 2-die Set .50bmg

Specifications

The Lee Collet 2-die Set .50bmg is specifically designed for the colossal .50 BMG cartridge. Its core components are the Collet Neck Sizing Die and the Bullet Seating Die. The dies feature the Lee Large Series threading, which is a standard 1 1/4 x 12 thread, making them compatible with many reloading presses, though their intended use is restricted to the Lee Classic Cast Press.

The Collet Neck Sizing Die is the star of this set. It utilizes a collet that grips the case neck and sizes it uniformly without working the entire case body. This method helps maintain proper case headspacing and significantly reduces case stretching, thereby extending the usable life of your expensive .50 BMG brass.

The Bullet Seating Die is a standard component that ensures consistent seating depth of your projectiles. While not as revolutionary as the collet die, its inclusion provides a complete neck sizing and bullet seating solution in a single package. It’s important to remember that this set does not include a shell holder or a powder dipper, which are separate purchases.

Performance & Functionality

The primary job of this die set is to neck-size .50 BMG cases to optimize them for re-use, and in this regard, it performs exceptionally well. The Collet Neck Sizing Die provides a consistent and controlled reduction of the case neck diameter. This results in a snug fit for the bullet upon seating, crucial for achieving tight ballistic consistency.

A significant strength is the extended case life it promotes. By only sizing the neck, it minimizes the stress on the case body, which is particularly beneficial for a cartridge as potent as the .50 BMG. This means fewer cases are discarded due to overworking.

One minor point of consideration is that it does not full-length resize. For most handloaders using this set, this is intentional, as they are likely not experiencing chambering issues and prefer to preserve case dimensions as much as possible. However, if a case becomes significantly sticky or hard to chamber, a separate full-length resizing die would still be necessary.

Design & Ergonomics

The design of the Lee Collet 2-die Set .50bmg is purely functional, prioritizing durability and ease of use over aesthetics. The dies are made from robust steel, with a practical, unpolished finish. They feel substantial and well-machined, conveying a sense of confidence in their ability to withstand the pressures associated with reloading for the .50 BMG.

Ergonomically, the dies are designed to thread smoothly into a press. The knurled portion at the top of the die bodies provides adequate grip for making adjustments. There’s a slight learning curve with collet dies, mainly in understanding how much pressure to apply for the desired sizing, but once understood, they are very intuitive.

The inclusion of clear instructions with the set is a helpful addition, guiding users through the setup and adjustment process. The overall feel is that of a tool built for serious work, not for display.

Durability & Maintenance

From my experience, these dies are built to last. The hardened steel collet and die bodies are resistant to wear and deformation, even with repeated cycles of heavy-duty reloading. I haven’t encountered any signs of premature failure or noticeable degradation in performance over time.

Maintenance is refreshingly simple. A periodic cleaning with a brass brush and a light application of a quality lubricant on the threads are usually sufficient. It’s advisable to keep the collet mechanism clean and free of debris to ensure smooth operation.

The only potential long-term concern with any die set is thread wear, but given the quality of the Lee manufacturing, this is unlikely to be an issue for most users operating within the specified press limitations. The simplicity of the design means there are very few points of potential failure.

Accessories and Customization Options

This particular set includes the essential Collet Neck Sizing Die and the Bullet Seating Die. As noted, it does not come with a shell holder or powder dipper. These are critical accessories that must be purchased separately to begin reloading.

Beyond the core dies, Lee offers a range of complementary reloading components, such as primers, powders, and projectiles, which would be necessary for completing your ammunition. For those already invested in the Lee reloading ecosystem, compatibility is generally excellent.

While the dies themselves aren’t typically “customized” in the traditional sense, the Lee system allows for adjustment of the collet pressure, offering a degree of user-defined sizing. This fine-tuning is where the true “customization” of the sizing process occurs, tailored to your specific firearm and brass.
