Was the **Evolution Gun Works Undersize Reloading Die** the Right Choice?
For serious handloaders, especially those dealing with cartridges fired from less-than-perfect chambers, a reliable sizing die is paramount. The Evolution Gun Works Undersize Reloading Die, manufactured by Lee Precision, promises to address common reloading frustrations. My experience with brass fired from a particular Glock model, known for its looser chambers, led me to seek a solution beyond standard dies. This undersized die, featuring a radiused base and carbide construction, piqued my interest as a potential answer to persistent feed failures. Initial impressions of the die reveal a solid, no-nonsense tool that feels built to last. While I briefly considered more generic carbide dies, the specific promise of an extra 0.003″ sizing and enhanced base resizing set this unit apart. My immediate reaction was one of cautious optimism, hoping it would finally solve a persistent bottleneck in my reloading process.
Real-World Testing: Putting **Evolution Gun Works Undersize Reloading Die** to the Test
First Use Experience
My initial testing took place on my dedicated reloading bench, amidst a batch of 9mm brass notorious for its bulged bases. The setup was straightforward, following the provided instructions to seat the die until it touched the shellholder. Performance was immediately noticeable; the carbide surface required no lubrication, a welcome change, and the die sized the brass down effectively, including the area near the base. I experienced no feed failures with cartridges resized using this die, a stark contrast to my previous results. The process felt smooth, and the die’s ability to handle cases without lubrication was a significant improvement.
Extended Use & Reliability
After several weeks and hundreds of cases processed, the Evolution Gun Works Undersize Reloading Die has proven its mettle. It continues to size brass consistently, and the carbide surface shows no signs of wear or performance degradation. Cleaning is as simple as wiping it down, and no special maintenance beyond occasional inspection is required. Compared to my older, standard sizing dies, this undersized unit offers a tangible improvement in reliability, especially with problematic brass. The cases even appear to have a slightly burnished finish after passing through the die.
Breaking Down the Features of **Evolution Gun Works Undersize Reloading Die**
Specifications
This reloading die is constructed from carbide, a material renowned for its extreme hardness and durability. It is manufactured by Lee Precision for Evolution Gun Works. The key specification is its 0.003″ undersize diameter compared to standard dies, combined with a radiused bottom corner. This design choice is crucial for resizing cases further down, addressing bulges near the base. The carbide construction eliminates the need for case lubrication, a significant convenience and time-saver. The die also features a collet-retained decapping pin, designed to slide harmlessly if obstructed rather than breaking.
Performance & Functionality
The primary function of the Evolution Gun Works Undersize Reloading Die is to reliably resize spent brass, particularly for cartridges fired in looser chambers. It excels at this task, consistently reducing case diameter and eliminating base bulges that can cause feeding issues. The no-lube-required aspect is a major functional advantage, simplifying the reloading process and reducing mess. Its ability to effectively size brass fired from Glocks and similar firearms is a significant performance benefit for many reloaders.
Design & Ergonomics
The die features a robust carbide construction, giving it a substantial feel and promising longevity. The undersized diameter and radiused base are the standout design elements, directly addressing specific reloading challenges. The collet system for the decapping pin is a thoughtful ergonomic feature, designed to prevent damage from obstructions. While not inherently an “ergonomic” tool in the same way a grip is, its design minimizes the effort required from the reloader due to its efficient sizing action.
Durability & Maintenance
Given its carbide construction, this die is engineered for exceptional durability, promising a “lifetime” of use for the serious reloader. Carbide is incredibly hard, resisting wear and abrasion far better than steel. Maintenance is minimal; a simple wipe-down after use is usually sufficient. The collet-style decapping pin is designed for easy reset should it become overstressed, preventing catastrophic failure and ensuring continued usability.
Accessories and Customization Options
While the die itself is a standalone component, extra decapping pins are available for purchase separately, which is a practical consideration for any reloader. The die is compatible with Dillon reloading presses, specifically the 550, 650, and 1050 models, though it will not work with “squared” press designs. No other significant customization options are inherent to the die itself, as its specialized nature is its core offering.
Pros and Cons of **Evolution Gun Works Undersize Reloading Die**
Pros
- Effectively sizes bulged brass, particularly from Glocks and other loose-chambered firearms.
- Carbide construction eliminates the need for case lubrication.
- Extremely durable, designed to last a lifetime.
- Radiused bottom corner sizes cases further down, addressing base bulges.
- Collet-style decapping pin offers protection against obstructions.
Cons
- May not be necessary for reloaders who don’t encounter significantly bulged brass.
- Requires some initial torque and a wrench for secure installation, which might be a minor inconvenience for some.
Who Should Buy **Evolution Gun Works Undersize Reloading Die**?
This die is an indispensable tool for serious handloaders who frequently reload 9mm ammunition that has been fired in firearms with looser chambers, such as many Glocks. If you have experienced feeding issues with your reloaded ammunition due to bulged cases, this product is a highly recommended solution. It is particularly beneficial for those who reload high volumes of brass. However, if you primarily reload brass from tighter chambers or have not encountered base bulging issues, a standard sizing die might suffice, and this specialized unit may be unnecessary. For optimal use, ensure you have the appropriate shellholder and a reloading press compatible with its design, such as a Dillon 550, 650, or 1050.
Conclusion on **Evolution Gun Works Undersize Reloading Die**
The Evolution Gun Works Undersize Reloading Die is a precision tool that delivers on its promise to solve a common and frustrating reloading problem. Its carbide construction and specialized 0.003″ undersize diameter with a radiused base make it a superior choice for resizing brass that has been fired in looser chambers. The elimination of the need for case lube is a significant convenience that streamlines the reloading process. While its price point of $31.99 is reasonable for a die of this quality and specialization, it’s an investment that pays dividends in terms of improved reliability and reduced frustration. For any handloader who has wrestled with bulged 9mm brass, this die is not just a purchase, but a solution that I can confidently recommend. It’s a testament to how a small but significant design tweak can make a world of difference in the consistency and functionality of reloaded ammunition.
