Lyman H&i Sizing Die .338

• Precise .338 sizing: This H&I sizing die is made for .338 bullets, helping cast projectiles reach a consistent final diameter that supports better fit in the bore and more uniform downrange results.
• Body sizing operation: The die is built to size the bullet body cleanly and consistently, which is important when loading cast bullets that need dependable dimensions for smooth chambering and stable accuracy.
• Hardened steel construction: A steel sizing die stands up well to repeated use on the loading bench, giving reloaders a durable tool for regular cast-bullet production.
• Tapered-mouth alignment: Lyman H&I sizing dies use a tapered mouth to guide bullets into the die more smoothly, helping maintain alignment and preserve a more uniform cylindrical shape during sizing.
• Fits standard equipment: With a standard 7/8"-14 thread, this die works with common compatible presses and integrates easily into established reloading setups.

About the H&I Series

Lyman H&I sizing dies are part of the company’s long-established cast-bullet reloading and bullet-casting range. These dies are intended for reloaders who cast their own bullets and need a practical way to bring them to a controlled final diameter while preparing them for lubrication in a compatible lube-sizer setup. Within Lyman’s lineup, the H&I series fills a specific role: it is not a general rifle or pistol die set, but a dedicated tool for bullet finishing after casting.

The series is built around straightforward, workshop-focused design. A tapered mouth helps start the bullet into the die more smoothly, while the hardened interior is intended to support alignment and maintain a consistent cylindrical form during sizing. Lyman also updated these dies with 90° hole spacing to make bullet lubrication easier, including with harder modern lubricants. Because the range covers many popular diameters, H&I dies are widely used by handloaders who want to tune cast bullets to a particular barrel, cartridge, or application without adding unnecessary complexity to the process.

About the Lyman H&i Sizing Die .338

The Lyman H&i Sizing Die .338 is a dedicated bullet-sizing tool for reloaders working with .338 cast bullets. Its job is simple but important: bring cast bullets to a controlled final diameter before loading, so the finished projectile is better matched to the firearm and more consistent from one round to the next. For cast-bullet shooters, that consistency matters in both accuracy and handling, especially when trying to reduce variation across a batch.

This model uses body sizing, making it suitable for the finishing stage of cast-bullet preparation rather than case resizing. In practical use, that means it supports a cleaner, more repeatable workflow for bullet casting and handloading. The steel construction is appropriate for repeated bench use, while the standard adjustment format keeps setup straightforward for reloaders who prefer conventional tooling rather than specialized bushing systems.

Compatibility is also a strong point. The die uses a standard 7/8"-14 thread, so it fits common press setups without requiring unusual adapters. As part of Lyman’s H&I system, it is designed to work in bullet sizing and lubricating applications where correct bullet diameter is essential. For reloaders building cast loads around the .338 diameter, this die offers a focused, durable solution that supports uniform bullet dimensions and a more controlled loading process.

About Lyman

The Lyman Gun Sight Company began in 1878 in Middlefield, Connecticut, and the brand has long been associated with practical tools for shooters and reloaders. Lyman makes equipment and accessories for shooting and reloading, with product lines that include reloading dies, presses, bullet-casting equipment, and gun sights. That broad focus helps explain why the company remains closely tied to traditional handloading as well as sighting equipment.

Over time, Lyman expanded its role in the reloading market. Lyman acquired the Ideal reloading-tool business in 1925, strengthening its position in handloading equipment, and Lyman Products is headquartered in Middletown, Connecticut. For products such as bullet sizing dies, the company is especially well known for bench tools aimed at reloaders who want dependable, workshop-oriented equipment rather than overly complicated systems.
