Lyman Neck Expanding Pistol (M) Dies Review

Let’s Dive into Lyman Neck Expanding Pistol (M) Dies

The Lyman Neck Expanding Pistol (M) Dies are a critical component for reloaders seeking precision and consistency, especially when working with lead or plated bullets. These dies are designed to expand the case neck of pistol cartridges, ensuring proper bullet seating and preventing bullet damage during the reloading process. Lyman, a trusted name in reloading equipment, has crafted these dies to address the specific needs of reloaders who prioritize accuracy and bullet integrity.

I’ve been reloading for over a decade, and one of the biggest challenges I’ve faced is achieving consistent neck tension, particularly with lead bullets. Often, seating a lead bullet without expanding the neck results in shaving lead, leading to poor accuracy and increased fouling. I was looking for a die that could expand the case neck precisely and consistently, without over-expanding or damaging the brass.

Upon unboxing, the Lyman Neck Expanding Pistol (M) Dies immediately impressed me with their solid construction and precise machining. The die felt substantial in hand, and the finish was smooth and consistent, indicating a high level of quality control. It was immediately clear that Lyman prioritized quality when manufacturing this product.

I considered the Lee Universal Case Expanding Die and the RCBS Expander Die. The Lyman die, however, was the clear winner due to its two-step design, which I believed would provide a more controlled and accurate expansion compared to the simpler designs of the other dies. The price point of $25.49 was also competitive, making it an easy decision.

My first impression was one of excitement and anticipation. I was eager to see if the Lyman Neck Expanding Pistol (M) Dies would live up to their promise and improve the accuracy and consistency of my reloads. I was ready to put them to the test and find out if they were a worthwhile addition to my reloading bench.

Real-World Testing: Putting Lyman Neck Expanding Pistol (M) Dies to the Test

First Use Experience

My first test of the Lyman Neck Expanding Pistol (M) Dies was at my home reloading bench, where I typically reload 9mm and .45 ACP cartridges. I specifically tested the dies with both lead and Berry’s plated bullets to evaluate their performance with different bullet types. The ammunition was then tested at my local outdoor range.

During the initial reloading process, I experienced variations in case neck tension depending on the specific type of brass used. Consistent neck tension is incredibly important, which allows for uniform powder ignition and consistent pressures behind the bullet. The Lyman die worked flawlessly to consistently create that uniform tension, allowing for proper seating of the bullet.

The dies were incredibly easy to use; I simply installed them in my reloading press like any other die. The two-step expansion process was smooth and consistent, and I quickly found the optimal adjustment for my specific bullet diameters. After a few practice rounds, the process felt intuitive and efficient.

My initial concern about over-expanding the case mouth proved unfounded. The Lyman Neck Expanding Pistol (M) Dies provided a gentle and controlled expansion, perfectly preparing the case for bullet seating. No crushed or damaged cases were found.

Extended Use & Reliability

After several months of regular use, the Lyman Neck Expanding Pistol (M) Dies continue to perform reliably and consistently. I’ve reloaded thousands of rounds with these dies, and I’ve yet to experience any significant issues or failures. The Lyman die has proven itself to be a dependable piece of equipment.

The dies show no signs of wear and tear despite frequent use. The finish remains smooth and intact, and the internal components continue to function flawlessly. This durability gives me confidence that these dies will last for many years to come.

Cleaning and maintaining the Lyman Neck Expanding Pistol (M) Dies is straightforward. A quick wipe down with a clean cloth and a light application of gun oil are all that’s needed to keep them in top condition. I’ve found that this simple maintenance routine helps to ensure smooth and consistent operation.

Previously, I used a simple chamfering tool to expand case mouths. The Lyman die represents a significant upgrade in both precision and efficiency. The consistency in neck tension and the ease of use have noticeably improved the quality of my reloads, significantly outperforming my previous method.

Breaking Down the Features of Lyman Neck Expanding Pistol (M) Dies

Specifications

The Lyman Neck Expanding Pistol (M) Dies are designed to fit all popular reloading presses using the industry-standard 7/8″ x 14 threads. This compatibility ensures that they can be easily integrated into almost any reloading setup. Lyman designed these dies to be adaptable to various press types.

The dies feature a two-step expansion process. The first step expands the inside of the case neck to just under bullet diameter, creating precise case neck tension. This is crucial for achieving consistent bullet seating and preventing bullet setback. The second step expands the case mouth to bullet diameter or slightly over. This allows the bullet to be started perfectly centered and properly aligned, which promotes accuracy.

The manufacturer is Lyman, a company with a long-standing reputation for producing high-quality reloading equipment. This is important because it assures users that they are investing in a reliable and well-engineered product. Lyman‘s commitment to quality is evident in the design and construction of these dies.

These dies are specifically designed for pistol cartridges. This matters because pistol cartridges often require different expansion techniques compared to rifle cartridges due to their shorter case necks and different bullet types.

Performance & Functionality

The Lyman Neck Expanding Pistol (M) Dies excel at their primary function: expanding the case neck of pistol cartridges to facilitate proper bullet seating. They do so consistently and precisely, resulting in improved accuracy and reduced bullet deformation. Lyman has built a superior product for reloaders.

The greatest strength of these dies is their ability to create consistent neck tension, which is essential for achieving uniform bullet release and minimizing velocity variations. However, they may require some initial adjustment to find the optimal expansion for different bullet diameters and brass thicknesses. The Lyman die excels where others fall short.

The Lyman Neck Expanding Pistol (M) Dies meet and even exceed my expectations. I was hoping for an improvement in the consistency of my reloads, and that’s exactly what I got. I have seen an improvement in my group sizes at the range and a noticeable reduction in bullet deformation.

Design & Ergonomics

The Lyman Neck Expanding Pistol (M) Dies are constructed from high-quality steel. They offer both durability and longevity. The weight of the die feels solid and reassuring, indicative of the quality of materials used.
