Lee Bottle Neck Factory Crimp Pistol Die For 400 Corbon 90173 Review

Was the Lee Bottle Neck Factory Crimp Pistol Die For 400 Corbon 90173 Worth It?

For anyone delving into the world of handloading, especially for specialized cartridges like the .400 Cor-Bon, having the right tools is paramount. The Lee Bottle Neck Factory Crimp Pistol Die For 400 Corbon 90173 is one such tool that promises to deliver consistent, factory-like crimps for autoloader rounds. This die, from the reputable Lee Precision, aims to solve a common reloading challenge: ensuring consistent bullet seating and retention, critical for safe and reliable firearm function.

My journey to this specific die was driven by a desire for precision and repeatability in my reloads. While standard dies can offer a taper crimp, the “bottle neck” aspect of the .400 Cor-Bon cartridge, while subtle, presents unique challenges for seating and crimping. I needed a solution that could handle this particular case shape without imparting excessive force or uneven pressure. After exploring several options, the promise of a “factory crimp” from Lee seemed like the most direct route to achieving the desired outcome.

Upon receiving the die, the initial impression was one of characteristic Lee simplicity and robust engineering. It arrived in a straightforward plastic casing, typical for their reloading dies. The die itself felt substantial, with the hallmark of quality in its clean machining. There was a reassuring weight to it, suggesting it was built to withstand the rigors of regular use in a reloading press.

I had considered other crimp die manufacturers, particularly those known for their higher-end offerings, but the specific application for the .400 Cor-Bon and the consistent feedback on Lee‘s efficacy in their “Factory Crimp” line led me back to this model. The price point was also a significant factor; it offered a compelling blend of functionality and affordability. My excitement was a mix of anticipation for solving a reloading puzzle and a mild curiosity about how this specialized die would perform compared to more generalized tools.

Real-World Testing: Putting Lee Bottle Neck Factory Crimp Pistol Die For 400 Corbon 90173 to the Test

My testing grounds were the familiar confines of my dedicated reloading bench in my workshop, a space where precision and consistency are not just desired, but essential. The primary scenario for this die is, of course, the final stage of bullet seating and crimping for .400 Cor-Bon cartridges destined for my pistol. This involves carefully resizing, priming, powder charging, and finally, seating the bullet before applying the crimp.

The initial use was surprisingly straightforward. Adjusting the die to achieve the desired crimp was as simple as backing off the lock ring and turning the die body. I found that by carefully cycling a few test rounds through the press, I could quickly dial in the perfect amount of taper crimp, ensuring the bullet was held firmly without deforming the case mouth excessively. The Lee die performed this task with remarkable uniformity across multiple rounds, which is exactly what I was hoping for.

Over several weeks of reloading sessions, the Lee Bottle Neck Factory Crimp Pistol Die For 400 Corbon 90173 has become an indispensable part of my process. I’ve loaded dozens of .400 Cor-Bon cartridges with it, and each one emerges with a consistent, professional-looking crimp. There have been no hiccups, no jamming issues, and no reduction in performance.

Durability is not a question with Lee dies, and this one is no exception. After considerable use, there are no visible signs of wear on the die body or the internal crimping mechanism. Maintenance is minimal; a quick wipe-down with a dry cloth after use and a light application of universal de-greaser on the threads every few months keeps it in perfect working order. Compared to some older, less refined crimp dies I’ve used from lesser-known brands, this Lee die is a testament to efficient design and enduring quality.

Breaking Down the Features of Lee Bottle Neck Factory Crimp Pistol Die For 400 Corbon 90173

Specifications

The Lee Bottle Neck Factory Crimp Pistol Die For 400 Corbon 90173 is a specialized tool designed for reloaders. It features a carbide sizer die, which is a significant advantage as it sizes the cartridge case while it is being crimped. This dual-action capability streamlines the reloading process and ensures consistency. The die includes an adjusting screw, allowing for quick and easy setting of the desired crimp depth. Crucially for autoloader rounds like the .400 Cor-Bon, it applies a perfect taper crimp.

The carbide sizing component is a notable spec because it eliminates the need for separate sizing and crimping steps for many bottleneck pistol cartridges. This not only saves time but also reduces the risk of errors in case manipulation. The taper crimp function is precisely engineered to secure the bullet in place without causing excessive stress on the case neck, which is vital for reliable feeding in semi-automatic firearms. The adjustability of the crimp via the screw means you can tailor it to specific bullet types and reloading data.

Performance & Functionality

In its primary role, the Lee Bottle Neck Factory Crimp Pistol Die For 400 Corbon 90173 excels. It reliably produces a uniform taper crimp that holds bullets securely in place. This ensures that rounds chamber and eject smoothly, and critically, prevents bullet setback during recoil, a common issue with improperly crimped ammunition. The die’s ability to size and crimp simultaneously is a significant functional advantage, simplifying the reloading sequence.

The main strength of this die is its ability to achieve a consistent, factory-like crimp specific to bottleneck pistol cartridges. This level of repeatability is hard to match without specialized tooling. On the downside, it is a single-purpose die; while effective, it doesn’t offer the multi-functionality of some other reloading dies. However, for its intended purpose, its performance is exceptionally high.
