Lee Undersize Sizing Die Only Carbide .38 Super Review

The Truth Revealed: Lee Undersize Sizing Die Only Carbide .38 Super

For serious reloaders, the quest for consistent, reliable brass is a never-ending journey. My own path led me to the Lee Undersize Sizing Die Only Carbide .38 Super, a component aimed at addressing the critical first step of case preparation. As an equipment specialist with over a decade immersed in diverse environments – from the gritty reality of workshop benches to the meticulous demands of lab settings and the unpredictable nature of field use – I approach new gear with a critical, experienced eye. This particular die promised a specific solution to a common reloading frustration: inconsistent case neck diameter after resizing, which can lead to feeding issues and reduced accuracy.

My initial motivation for acquiring this specific sizing die stemmed from a batch of .38 Super brass that, after standard resizing, exhibited just enough variation in neck tension to cause me concern. Feeding issues, though minor, were cropping up more frequently than I liked, and I knew that precise case dimensions were paramount for optimal performance, especially in a high-pressure cartridge like the .38 Super. While Lee Precision is a well-respected name in the reloading community, known for its innovative and often budget-friendly solutions, I was keen to see if this carbide offering lived up to its promise of enhanced precision.

Upon unboxing, the die presented a familiar, robust feel typical of Lee’s carbide offerings. The clean, machined surfaces and the distinctive carbide ring hinted at its intended purpose and durability. It’s a utilitarian piece, designed for function over form, and that’s exactly what I expected. I had briefly considered some of the higher-end, custom-ground sizing dies on the market, but their significantly higher price point and often longer lead times made them impractical for my immediate need. This Lee die, at a fraction of the cost and readily available, seemed like the sensible, pragmatic choice. A small sense of anticipation, a quiet hope that this would indeed solve my brass consistency issues, settled in.

Real-World Testing: Putting **Lee Undersize Sizing Die Only Carbide .38 Super** to the Test

First Use Experience

My testing grounds for this resizing die were my dedicated reloading bench in the workshop, a space where precision and repeatability are paramount. I loaded up a variety of once-fired .38 Super brass, sourced from different firearms and shooting conditions, to truly challenge its capabilities. The process involved dropping the brass into my progressive press and running it through the die, observing the feel and sound as the cases were resized.

Performance was notably consistent, even with brass that had seen considerable use or slight deformation. The carbide ring slid smoothly over the brass, and the die consistently brought the cases down to a uniform diameter. There were no grinding sensations or excessive force required, which is a testament to good manufacturing. It was immediately intuitive; if you’ve ever used a resizing die, this one presents no learning curve.

One minor surprise was the slight difference in feel compared to my older, standard steel sizing dies. The carbide surface offers a different kind of friction, a smoother, almost frictionless glide that I found quite pleasing. No issues or quirks presented themselves during this initial run; it simply did its job as advertised.

Extended Use & Reliability

Over several weeks and hundreds of rounds processed, the Lee Undersize Sizing Die Only Carbide .38 Super has proven its mettle. It remains a staple in my .38 Super reloading process, consistently resizing brass with a uniformity I hadn’t achieved before. I’ve run batches of brass through it perhaps fifty times now, and there’s absolutely no discernible degradation in performance.

Durability is clearly a strong suit. Despite being exposed to the usual workshop environment – dust, occasional minor splashes of case lube, and the general wear and tear of a reloading bench – the carbide surface shows no signs of wear, scratching, or performance degradation. The die feels as solid and precise as it did on day one.

Maintenance is incredibly straightforward. A quick wipe down with a clean cloth after a reloading session is all that’s typically needed to keep it in top condition. Occasionally, a light spritz of solvent to remove any stubborn lube residue ensures its longevity. I haven’t encountered any specific maintenance concerns; it’s a set-it-and-forget-it kind of component for the most part. Compared to standard steel dies that can eventually wear down or rust if not meticulously cared for, the carbide construction of this Lee die offers a significant advantage in terms of reduced maintenance and increased lifespan.

Breaking Down the Features of **Lee Undersize Sizing Die Only Carbide .38 Super**

Specifications

The Lee Undersize Sizing Die Only Carbide .38 Super is a single die designed for resizing the case necks of .38 Super cartridges. It specifically caters to those who need to reduce the case diameter beyond standard specifications, ensuring a tighter fit in the chamber and consistent bullet tension. The die is constructed with a hardened steel body and features a carbide sizing ring, which is crucial for its performance.

The carbide sizing ring eliminates the need for case lubrication, a significant advantage that speeds up the reloading process and reduces the mess associated with it. This specific die is for the .38 Super caliber, with the product details listing it as “.38acp/.38 super auto”. It is sold as a single die, meaning it’s meant to be integrated into an existing reloading setup or ordered as a replacement part. The dimensions provided are 1.60 x 1.70 x 4.70 inches, which are standard for most reloading dies and should fit any common reloading press.

The presence of a carbide sizing ring is the most critical specification. Unlike steel dies, carbide rings are significantly more durable and resist wear much better, eliminating the need for lubrication. This means faster reloading cycles and less time spent cleaning cases and dies. The “undersize” nature of the die means it will size the case mouth and neck to a slightly smaller diameter than a standard sizing die, which is beneficial for cases that have expanded excessively or for achieving a more consistent neck tension.

Performance & Functionality

The primary job of this die is to resize fired brass cases, specifically to undersize them. In this regard, the Lee Undersize Sizing Die Only Carbide .38 Super performs exceptionally well. It consistently brings the case necks down to a uniform dimension, which is vital for reliable feeding and accurate bullet seating. I’ve noticed a marked improvement in case neck tension consistency after using this die, which translates directly into more predictable ballistic performance.

The biggest strength of this die is its ability to work without case lubricant. The carbide sizing ring allows cases to slide through smoothly, dramatically speeding up the resizing process and reducing cleanup. This is a significant advantage over traditional steel sizing dies. A minor weakness, if one can call it that, is that “undersize” might be too much for some applications; for standard .38 Super cases that haven’t excessively expanded, a standard sizing die might suffice. However, for cases that truly need to be brought down, this die excels. It meets and often exceeds expectations for consistency and ease of use, especially considering its price point.

Design & Ergonomics

The design of the Lee Undersize Sizing Die Only Carbide .38 Super is functional and straightforward, as one would expect from Lee Precision. The hardened steel body feels substantial and durable, providing a solid foundation for the critical carbide insert. The threading is standard and should fit seamlessly into most reloading presses.

Ergonomically, the die itself doesn’t have much in terms of grip or comfort features, as it’s designed to be mounted in a press and operated by the press handle. However, the smooth operation afforded by the carbide ring contributes to a comfortable reloading experience by reducing physical effort. The clean, uncluttered design means there are no extraneous parts to snag or get in the way. Markings on the die are clear and easy to read, indicating caliber and function. It’s a tool designed for efficiency, and its design supports that goal perfectly.

Durability & Maintenance

The durability of a carbide resizing die is its hallmark, and this Lee offering is no exception. Under normal reloading use, which I define as processing hundreds or thousands of cases over time, this die is built to last for many years, potentially a lifetime. The carbide sizing ring is exceptionally resistant to wear and abrasion, far more so than traditional steel dies.

Maintenance is minimal. A quick wipe-down after use is sufficient. Occasionally, using a small brush or a bit of solvent to clear out any debris from the die’s interior threads or around the carbide ring ensures it continues to function optimally. There are no obvious failure points; the critical component, the carbide ring, is extremely robust. The main concern for longevity would be cross-threading it into the press or dropping it, which could damage the threads or the carbide insert itself, but these are user-error risks rather than design flaws.

Accessories and Customization Options

This product is sold as a single die only, meaning it does not come with any additional accessories. It is designed to integrate into an existing reloading press and die set. Therefore, there are no direct customization options for the die itself.

However, its primary “accessory” is the lubricant-free resizing it enables, which in turn simplifies the entire reloading process. Compatibility is a key aspect here; this die uses standard 7/8″-14 thread pitch, making it compatible with virtually all standard reloading presses on the market. This ensures it can be easily added to any reloader’s existing toolkit without requiring specialized equipment.
