Lyman Sizing Dies (H&I) Review

Let’s Dive into Lyman Sizing Dies (H&I)

The Lyman Sizing Dies (H&I) are an essential tool for any serious cast bullet reloader, and Lyman has been a trusted name in reloading for generations. These dies are designed to ensure proper bullet diameter, which is critical for accuracy and consistent performance in your firearms. My journey to acquiring these dies began with a persistent problem: inconsistent cast bullet accuracy. I was chasing tighter groups and better ballistic consistency, realizing that my cast bullets weren’t always perfectly uniform in diameter.

I remember the day I received my first Lyman Sizing Die. The packaging was straightforward, but the die itself felt solid and well-made. The weight hinted at the hardened steel construction, and the smooth finish gave me confidence in its precision. Compared to some of the cheaper sizing methods I’d experimented with, like makeshift push-through sizers, the Lyman die was in a completely different league.

Initially, I was drawn to the Lyman Sizing Dies (H&I) over RCBS dies due to Lyman’s reputation for offering a slightly wider range of specific diameters. While both brands offer quality products, I needed a very specific diameter for a particular project, and Lyman had it. My first impression was one of cautious optimism – I was eager to see if this die could finally solve my accuracy woes and bring consistency to my cast bullet reloading.

Real-World Testing: Putting Lyman Sizing Dies (H&I) to the Test

First Use Experience

My initial testing took place at my reloading bench, feeding bullets through a Lyman 450 Lube-Sizer. The process was straightforward: lubricate the cast bullets, place them in the die, and use the sizer to push them through. I noticed the improved 90-hole spacing immediately; the lubrication was distributed far more evenly compared to older dies I’d used.

I tested the dies with a range of cast bullets, experimenting with different hardness levels and alloy compositions. I was initially concerned about leading in my older firearms. The Lyman Sizing Dies (H&I) helped to ensure a proper fit and seal, reducing the likelihood of leading and improving overall performance. There were no immediate issues, but I knew the real test would come with extended use.

Extended Use & Reliability

After months of regular use, the Lyman Sizing Dies (H&I) have proven to be incredibly reliable. The dies exhibit minimal wear and tear, even after sizing thousands of bullets. Maintenance is simple: I clean them periodically with a bore solvent and apply a light coat of oil to prevent rust.

Compared to some of the homemade sizing methods I used in the past, the Lyman Sizing Dies (H&I) are a quantum leap in consistency and ease of use. These dies consistently produce accurately sized bullets, leading to tighter groups and improved ballistic performance at the range. I can now confidently load cast bullets knowing they are properly sized and lubricated, a level of assurance I never had before.

Breaking Down the Features of Lyman Sizing Dies (H&I)

Specifications

• The Lyman Sizing Dies (H&I) are available in a wide range of diameters, from .224 to .512, catering to popular rifle and pistol calibers. This comprehensive selection ensures compatibility with a vast array of firearms.

• The dies feature a tapered mouth, which aids in bullet alignment and smooth entry. This design reduces bullet deformation during sizing.

• The hardened interior of the die ensures a consistent and precise sizing diameter throughout its lifespan. This promotes uniformity and accuracy in cast bullet reloading.

• Lyman’s improved design includes 90-hole spacing for lubricant distribution. This enables better and more even bullet lubrication, especially with harder lubes.

• The dies are interchangeable with RCBS Lube-A-Matic sizers, offering compatibility across different reloading setups. This provides flexibility for reloaders with existing equipment.

These specifications matter because they directly impact the accuracy and consistency of reloaded ammunition. The precise sizing, smooth bullet entry, and efficient lubrication all contribute to minimizing bullet deformation and ensuring a proper fit in the firearm’s bore, leading to improved ballistic performance.

Performance & Functionality

The Lyman Sizing Dies (H&I) perform their core function exceptionally well: accurately sizing cast bullets. They are reliable and consistent, producing bullets that meet the specified diameter. The dies contribute significantly to achieving tighter groups and improved ballistic consistency.

The strengths of these dies lie in their precision, durability, and ease of use. I have noticed no real weaknesses in their performance. They consistently meet and often exceed my expectations for cast bullet sizing.

Design & Ergonomics

The build quality is excellent, reflecting Lyman’s commitment to producing durable and reliable reloading equipment. The dies are made from hardened steel, ensuring long-lasting performance. Their weight and solid construction inspires confidence.

The design is user-friendly, with no significant learning curve. The tapered mouth and smooth interior make the sizing process easy and efficient. The 90-hole spacing dramatically improved lube distribution for me over older designs.

Durability & Maintenance

The Lyman Sizing Dies (H&I) are built to last. With proper care, they should provide years of reliable service. Maintenance is straightforward, involving periodic cleaning and lubrication.

I’ve not had to repair or replace any parts, testament to their robust construction. I anticipate these dies will be a staple in my reloading setup for many years to come.

Accessories and Customization Options

The Lyman Sizing Dies (H&I) are primarily standalone tools, designed to work with a Lyman Lube-Sizer or similar device. However, there are accessories that can enhance their performance. Lyman offers top punches in various shapes and sizes to accommodate different bullet designs.

These dies are compatible with Lyman’s line of lubricants, which are specifically formulated for cast bullets. You can also find aftermarket accessories, such as custom top punches and lube heaters, from other manufacturers. The intercompatibility with RCBS Lube-A-Matic sizers is a significant advantage.

Who Should Buy Lyman Sizing Dies (H&I)?

The Lyman Sizing Dies (H&I) are perfect for reloaders who cast their own bullets and demand consistent accuracy and reliable performance. This includes target shooters, hunters using cast bullets, and anyone seeking to optimize the performance of their reloaded ammunition. These dies are also a good choice for individuals who are new to cast bullet reloading, as they are easy to use and provide consistent results.

This product may not be necessary for reloaders who only use jacketed bullets, as these bullets are typically manufactured to precise dimensions. Those who are unwilling to invest in a lube-sizer tool should also skip this product, as the dies require a separate device to operate. A must-have accessory is a quality bullet lubricant, such as Lyman’s Alox or a similar product.

Conclusion on Lyman Sizing Dies (H&I)

The Lyman Sizing Dies (H&I) are an essential tool for anyone serious about cast bullet reloading. They offer exceptional accuracy, consistent performance, and long-lasting durability. The improved lube distribution and wide caliber selection make them a versatile and valuable addition to any reloading bench.

The price is justified by the quality and performance of these dies. You simply can’t achieve the same level of accuracy and consistency with cheaper sizing methods.
