Lee 90581 Powder Through Expanding Pistol Die .38 Special Review

Reviewing the Lee 90581 Powder Through Expanding Pistol Die .38 Special: Beyond Marketing

As a reloader, I’m constantly seeking tools that streamline the process, offering both efficiency and precision. My search for a more integrated powder charging and case expansion step led me to the Lee 90581 Powder Through Expanding Pistol Die .38 Special. For years, I’d handled these operations separately, often involving a dedicated powder funnel and a separate expanding die. This particular die promised to combine these two critical steps, a prospect that immediately caught my attention.

My initial impression upon receiving the die was one of practical simplicity. Machined from what appears to be solid brass, it has a reassuring heft and a clean, no-nonsense finish that speaks to its industrial purpose. There are no superfluous adornments, just a functional tool designed for a specific task.

Before settling on this Lee die, I’d considered other brands that offered similar inline expansion and priming components. However, many of those were part of larger, more expensive systems, or lacked the specific powder-through capability I was after. This particular model from Lee stood out for its targeted functionality and, frankly, its accessible price point. My immediate feeling was one of optimism – this might just be the missing piece to smooth out my .38 Special loading workflow.

Real-World Testing: Putting Lee 90581 Powder Through Expanding Pistol Die .38 Special to the Test

My testing grounds were my own reloading bench and the familiar environment of my indoor range. The primary goal was to integrate this die into my established progressive press setup for .38 Special, a caliber I load in significant quantities for both target practice and competition. I wanted to see how it performed with a variety of brass types and under consistent, high-volume use.

The first few cycles were a revelation. The die seamlessly expanded the case mouth while simultaneously allowing the powder charge to drop cleanly through its integrated funnel. This eliminated the need to remove the die to add powder, a small but significant time saver. I did notice a slight learning curve in ensuring consistent alignment with the powder drop, but after about fifty cases, it became second nature. The die handled brass of different ages and conditions without complaint, from recently tumbled to older, slightly tarnished cases.

After weeks of consistent use, cycling through hundreds of rounds of .38 Special, this Lee die has proven itself to be a workhorse. I haven’t observed any significant wear beyond the expected slight sheen on the brass from repeated interaction with cases and shell plates. Cleaning is straightforward; a quick wipe-down and the occasional brush through the powder funnel are all that’s needed. Compared to some aftermarket dies that can feel finicky or require precise adjustments, this expanding die from Lee has been remarkably forgiving and reliable, consistently performing its dual function with minimal fuss.

First Use Experience

My initial setup involved removing my existing expanding die and carefully threading the Lee 90581 Powder Through Expanding Pistol Die .38 Special into its place on my progressive press. The die screwed in smoothly, indicating good threading and tolerances. I then installed the powder funnel adapter, ensuring it was seated firmly. My first few pulls of the press handle were deliberate, observing the case as it entered the die and the powder charge being dispensed.

The process felt incredibly intuitive once I understood the sequence. The Lee die requires you to insert the sized case, which then engages the expanding button within the die. As the case continues to rise, a hole at the top of the die allows for a measured powder drop directly into the expanded case mouth. This eliminates an entire station on a press or a separate manual step with a powder funnel.

One minor surprise was the slight sound difference as the powder dropped; it was a bit louder than dropping powder directly into a funnel, likely due to the metal-to-metal interaction within the die. However, this was purely an auditory observation and had no impact on the powder’s accuracy or the die’s function.

Extended Use & Reliability

Having now processed well over a thousand rounds of .38 Special with the Lee 90581 Powder Through Expanding Pistol Die .38 Special, its reliability has become a given. There’s no detectable wobble or looseness in the die itself, and the expanding function remains crisp and consistent. Even after being exposed to the usual workshop dust and the occasional accidental smudge of case lube, its performance hasn’t degraded.

Maintenance is minimal, which is precisely what I look for in reloading components. A simple blast of compressed air clears out any residual brass shavings or powder dust. The ability to remove the powder funnel adapter for deeper cleaning is also a welcome feature, though I haven’t found it necessary yet. Compared to older, simpler expanding dies I’ve used, this model’s dual functionality has held up exceptionally well, proving its durability.

Breaking Down the Features of Lee 90581 Powder Through Expanding Pistol Die .38 Special

Specifications

The Lee 90581 Powder Through Expanding Pistol Die .38 Special is precision-machined from what feels like solid brass, offering a robust and durable construction. This material choice is common for dies as it provides good wear resistance and a pleasing heft. It is specifically designed for the .38 Special caliber, ensuring the correct case mouth expansion for subsequent bullet seating.

The key specification is its Powder Through Expanding Pistol Die functionality. This means it expands the case mouth and has an integrated funnel for powder charging simultaneously. It’s designed to work with a corresponding “Coke Through Expanding Die” if you’re using certain Lee turret presses, but functions independently as an expanding and powder-drop die on most progressive presses. The die also features a removable powder funnel adapter, which can be swapped out for a Lee Auto Disk Powder Measure for fully automated powder dispensing.

The brass construction contributes to its longevity and resistance to corrosion, crucial for a tool that experiences regular use and interaction with reloading components. The integrated powder funnel is a clever design element that directly addresses a common reloading bottleneck, allowing for a more fluid and efficient process. The compatibility with the Lee Auto Disk Powder Measure opens up further automation possibilities for those looking to streamline their reloading operations even more.

Performance & Functionality

The primary job of the Lee 90581 Powder Through Expanding Pistol Die .38 Special is to reliably expand the case mouth of spent .38 Special brass and to allow for powder charging in the same station. It excels at this dual purpose. The expanding plug is precisely sized to provide just enough flare for easy bullet seating without overworking the brass, which can lead to splitting.

Where this die truly shines is in its ability to integrate powder charging. This saves significant time by eliminating the need to remove the die, charge the case, and then replace the die. The powder drops cleanly through the central bore, ensuring that each charge lands accurately within the expanded case. This efficiency translates directly to faster reloading sessions and a more streamlined workflow.

Its performance is consistent, batch after batch. I haven’t encountered any instances of under-expansion or over-expansion, nor have I had issues with powder bridging or erratic drops when using my powder measure. The only caveat is that it relies on your existing powder dispensing system (manual funnel or automated measure) to deliver the charge.

Design & Ergonomics

The design of this Lee die is utilitarian and robust. The brass construction provides a comfortable grip when threading it into the press, and its weight feels substantial and reliable. The machining is clean, with no sharp edges or burrs that could snag on cases or cause discomfort.

The integrated funnel is elegantly simple, featuring a smoothly tapered opening that guides powder directly into the case. The removable adapter for the Auto Disk Powder Measure is a thoughtful addition, allowing for flexibility depending on your setup and preferences. It fits snugly and securely, ensuring no powder escapes around the adapter during operation.

Ergonomically, the die requires no special handling beyond normal reloading die practices. Its primary interaction is with the press itself, and its smooth operation contributes to a more pleasant reloading experience. The brass material also offers a classic aesthetic that many reloaders appreciate.

Durability & Maintenance

The brass construction of the Lee 90581 Powder Through Expanding Pistol Die .38 Special is a testament to its durability. Brass is inherently resistant to wear from repeated cycling and friction. After extensive use, the expanding plug remains perfectly sized, and the threads show no signs of stripping or damage.

Maintenance is refreshingly simple. A quick burst of compressed air after a reloading session is usually sufficient to clear out any brass shavings or powder residue. If deeper cleaning is ever needed, the powder funnel adapter can be easily removed by unscrewing it, allowing access to the internal passages.

I haven’t encountered any failure points with this die. It is built to withstand the rigors of reloading and is a testament to Lee Precision’s reputation for producing long-lasting reloading tools. Its simple design means there are very few components that can break or wear out over time.

Accessories and Customization Options

The primary “accessory” that integrates with the Lee 90581 Powder Through Expanding Pistol Die .38 Special is the powder funnel adapter itself. This adapter is designed to accept the Lee Auto Disk Powder Measure, allowing for a completely automated powder charging process within the same die station. This is a significant customization for those looking to maximize efficiency on their progressive press.

Beyond this, the die is a standalone component. However, its design implies compatibility with a wide range of Lee powder dispensing systems and potentially other aftermarket powder measures that can be adapted to fit the funnel’s opening. The .38 Special caliber means it’s purpose-built for that cartridge and does not offer caliber customization beyond that.

The ability to attach the Lee Auto Disk Powder Measure is the most impactful customization, transforming a manual step into an automated one. This offers significant value for high-volume reloaders seeking to speed up their process without compromising accuracy.
