Lee Powder 90585 Through Expanding Pistol Die 45 ACP Review

My Journey with the Lee Powder 90585 Through Expanding Pistol Die 45 ACP

As a gear and equipment specialist with over a decade of putting tools through their paces in diverse environments, I’ve developed a keen eye for what works and what doesn’t. My world spans the demanding conditions of outdoor expeditions, the precision required in workshops and labs, and the unforgiving nature of field use. Recently, my reloading bench, specifically my .45 ACP station, presented a recurring bottleneck. I was looking for a more streamlined way to charge cases as they were being prepped, a common desire among reloaders aiming to optimize their workflow. This led me to the Lee Powder 90585 Through Expanding Pistol Die 45 ACP, a component promising to integrate two crucial steps into one.

The need for this die became apparent during extended reloading sessions where manually dropping powder after expanding the case mouth felt like an unnecessary step, introducing potential for error or dropped charges. I had been using a standard expander die followed by a separate powder drop, a perfectly functional but less efficient method. The concept of a die that could perform both tasks simultaneously piqued my interest, offering the promise of faster, more consistent reloading. It’s a simple idea, but in the intricate dance of case preparation, even small optimizations can make a significant difference.

Upon receiving the Lee Powder 90585 Through Expanding Pistol Die 45 ACP, my initial impression was one of no-nonsense functionality. The die itself is constructed from what appears to be standard, robust steel, with a finely machined internal expander. It doesn’t scream “premium” in terms of aesthetic flair, but that’s precisely what I expect from a workhorse component like this; it’s built for purpose. I briefly considered other brands’ expander dies, but none offered this integrated powder-charging functionality, making the choice clear. My first reaction was a quiet satisfaction, a feeling that a simple, elegant solution to a persistent minor annoyance was finally within reach.

Real-World Testing: Putting Lee Powder 90585 Through Expanding Pistol Die 45 ACP to the Test

First Use Experience

I primarily tested the Lee Powder 90585 Through Expanding Pistol Die 45 ACP on my dedicated reloading bench in my workshop. This is where I typically process large batches of .45 ACP brass for both my competition handgun and general range use. The die integrated seamlessly into my existing Lee turret press, fitting as expected. The key was pairing it with the Lee Auto-Disk Powder Measure, which it’s designed to interface with, and that setup proved remarkably straightforward.

During initial use, the die performed consistently across about 100 cases. The expansion of the .45 ACP case mouth was adequate for reliably seating the powder drop and then subsequently seating a bullet. I ran into no significant issues, and the process felt natural after only a few repetitions.

The only slight surprise was a very minor learning curve in ensuring the powder measure aligned perfectly to drop powder after the case mouth was sufficiently expanded and the ram was near the top of its stroke. It wasn’t a problem, just a subtle adjustment in feel and timing that became second nature quickly. This is typical for any new die added to a progressive or turret press setup.

Extended Use & Reliability

After several months and well over a thousand rounds processed with this setup, the Lee Powder 90585 Through Expanding Pistol Die 45 ACP has proven itself to be a reliable workhorse. I’ve used it with various types of .45 ACP brass, including spent range brass that can sometimes vary slightly in dimensions. The die has consistently performed its dual function without any noticeable decrease in performance or accuracy.

There are no visible signs of wear and tear, such as cracks, unusual stiffness in the expander, or any degradation in its finish. The steel construction appears durable enough to withstand years of regular use. Cleaning is straightforward; a quick wipe-down with a cloth and a bit of solvent is usually all it needs. I occasionally apply a drop of universal case lube to the expander stem, but this is more preventative maintenance than a necessity for continued function.

Compared to other expander dies I’ve used over the years, this integrated design is significantly more efficient. It streamlines the reloading process considerably, especially when combined with the Auto-Disk measure. It certainly outperforms simpler, single-function expander dies in terms of workflow optimization.

Breaking Down the Features of Lee Powder 90585 Through Expanding Pistol Die 45 ACP

Specifications

The Lee Powder 90585 Through Expanding Pistol Die 45 ACP is precisely what its name suggests: a pistol die specifically for the .45 ACP caliber, designed to expand the case mouth while simultaneously allowing for powder charging. It features a precision-machined steel expander plug that gently flares the case mouth. This die is designed to work with Lee’s Auto-Disk Powder Measure, allowing the powder funnel adapter to be swapped out for the measure for automated powder dispensing.

The .45 ACP caliber specification is critical; while expander dies can sometimes be adaptable, this one is specifically tuned for the case dimensions of the .45 ACP. The pistol gun type designation reinforces its intended application. The exclusive Powder Through Expanding Die feature is Lee’s innovation here, integrating powder charging into the expansion step. This functionality is crucial for reloaders looking to shave time off their processes without sacrificing accuracy.

Performance & Functionality

The core function of this die is to expand the case mouth sufficiently to allow for bullet seating without shaving lead or brass, and to do so in a way that facilitates powder charging. The Lee Powder 90585 Through Expanding Pistol Die 45 ACP excels at this. The expansion is consistent, creating a reliable platform for bullet seating and ensuring that dropped powder funnels cleanly.

Its main strength is this integrated dual-action capability. By combining expansion and powder charging, it significantly speeds up the reloading cycle on a turret or progressive press. A minor weakness, though not inherent to the die itself, is that it relies heavily on the proper functioning and calibration of the paired powder measure. If the powder measure is inconsistent, the die will simply be passing that inconsistency along. However, when paired correctly, it’s a robust performer.

It meets and arguably exceeds expectations for its intended purpose, especially considering its modest price point. It performs its primary functions reliably and efficiently, making it a valuable addition to any .45 ACP reloader’s toolkit.

Design & Ergonomics

The design of the Lee Powder 90585 Through Expanding Pistol Die 45 ACP is fundamentally utilitarian. It’s constructed from durable steel, giving it a substantial feel. The internal expander is shaped to provide a smooth, gradual flare, minimizing stress on the brass.

Ergonomically, the die functions passively within a press. The user’s interaction is minimal, primarily involving the setup and adjustment on the press. Once set, its operation is dictated by the press’s ram movement. The standard threading for case reloading dies means it fits seamlessly into most reloading presses without issue. There’s no real “grip” or “feel” to the die itself during operation, as it’s meant to be a fixed component in the press.

Durability & Maintenance

Based on its construction and my extended use, the Lee Powder 90585 Through Expanding Pistol Die 45 ACP is built for longevity. The steel construction is a hallmark of durability for reloading components. I anticipate it will last for many thousands, if not tens of thousands, of rounds before any significant wear becomes apparent.

Maintenance is refreshingly simple. A quick wipe-down after use, perhaps a light application of case lube to the expander stem periodically, is all that’s required. There are no complex parts to clean or maintain. Potential failure points are minimal; the expander stem could theoretically bend or break under extreme abuse, but this is highly unlikely with normal reloading practices.

Accessories and Customization Options

The primary “accessory” for the Lee Powder 90585 Through Expanding Pistol Die 45 ACP is its compatibility with the Lee Auto-Disk Powder Measure. This measure is available in various disk sizes to dispense different powder charges, and it features a quick-change disk system for easy adjustment. While not included with the die itself, it’s an essential partner for the die’s intended functionality.

The die itself offers minimal direct customization beyond ensuring it’s properly adjusted for case tension. However, its standard 7/8″-14 threading means it can be used in presses from virtually any manufacturer. The expander plug is specifically designed for .45 ACP and is not interchangeable with other calibers.
