Lyman Neck Size Die Review

Let’s Dive into Lyman Neck Size Die

The Lyman Neck Size Die is a specialized reloading tool designed for precision-minded reloaders who prioritize accuracy and extended case life. Manufactured by Lyman, a trusted name in reloading equipment, this die allows reloaders to size only the neck of the cartridge case, preserving the fire-formed dimensions of the case body. This approach enhances accuracy by ensuring a snug fit within the rifle’s chamber, leading to more consistent bullet seating and improved shot-to-shot consistency.

My pursuit of this die stemmed from a desire to improve the consistency of my .204 Ruger loads. I was chasing tighter groups at longer ranges, and I knew that minimizing case inconsistencies was a crucial step. I was looking for a die that offered precise neck sizing without overworking the brass.

Upon unboxing the Lyman Neck Size Die, I was immediately impressed by the solid construction. The die felt substantial in hand, crafted from quality steel with a smooth, polished finish. It included the die body, a decapping rod, and an expander button, all neatly packaged and ready for use.

Compared to full-length sizing dies or bushing dies, the Lyman Neck Size Die offered a specific advantage: it sizes only the neck. This reduces stress on the brass and extends case life. I considered bushing dies for their adjustability, but opted for the Lyman die’s simplicity and focus on maintaining fire-formed dimensions.

My initial impression was one of cautious optimism. The Lyman Neck Size Die promised a path to greater accuracy and case longevity, and I was eager to see if it lived up to the hype. I was particularly excited to see how much the group sizes would shrink at 200 and 300 yards.

Real-World Testing: Putting Lyman Neck Size Die to the Test

First Use Experience

I tested the Lyman Neck Size Die at my local shooting range, focusing on accuracy at 100, 200, and 300 yards. I meticulously prepared a batch of .204 Ruger cases, carefully neck sizing each one with the Lyman die and loading them with consistent powder charges and bullets. The weather conditions were fairly stable, with a slight breeze, allowing for a relatively controlled testing environment.

The Lyman Neck Size Die was surprisingly easy to use right out of the box. The die screwed smoothly into my reloading press, and the decapping and neck sizing process was straightforward. I did not have to adjust to anything odd or unexpected.

The initial results were encouraging, but not dramatically different from my full-length sized loads. However, I noticed a slight improvement in consistency, with fewer “flyers” outside the main group. This suggested that the neck sizing was indeed contributing to more uniform bullet seating and chamber pressure.

Extended Use & Reliability

After several months of consistent use, the Lyman Neck Size Die has proven to be a reliable and durable tool. The die shows no signs of wear or damage, despite processing hundreds of cases. The Lyman Neck Size Die functions as it should.

Cleaning and maintaining the Lyman Neck Size Die is simple. A quick wipe-down with a clean cloth and a light application of gun oil after each reloading session is all that’s needed to keep it in good working order. The expander button has been easy to clean and maintain.

Compared to my previous experiences with full-length sizing dies, the Lyman Neck Size Die offers a noticeable advantage in case life. My cases are lasting significantly longer before needing to be trimmed or exhibiting signs of neck splitting. It definitely outperforms my previous experiences.
