Lyman H&i Sizing Die .430

• .430 sizing diameter: Sizes cast bullets to a consistent .430 diameter, helping maintain proper fit in the bore for more uniform accuracy and dependable lubrication.
• Body sizing operation: This die is built for straightforward bullet body sizing, making it a practical choice for reloaders who want a dedicated tool for cast-bullet preparation.
• Steel construction: The steel sizing die stands up well to repeated bench use and keeps its shape under regular loading-room work.
• Standard 7/8"-14 thread: Compatibility with presses that use the common 7/8"-14 thread makes it easy to integrate into an existing reloading setup.
• Made in the USA: U.S. manufacture is a strong fit for reloaders who value established production standards and easy continuity within Lyman casting equipment.

About the H&i Series

Lyman H&i sizing dies are part of the company’s long-established bullet-casting and reloading range, aimed at shooters who load cast bullets and want consistent finished diameter before use. Within Lyman’s lineup, these dies support the bullet-sizing and lubricating side of handloading rather than cartridge case work, making them especially relevant to revolver, pistol and rifle reloaders who tune cast bullets to a specific bore fit.

The series is built around a simple, durable concept: a hardened sizing die that brings bullets to a controlled diameter while supporting uniform shape through the sizing process. Lyman describes the current H&i design with 90° hole spacing for easier bullet lubrication, along with a tapered mouth and hardened interior to help alignment and maintain cylindrical form. In practice, that makes the H&i series well suited to reloaders who want repeatable bullet preparation, especially when working with harder lubricants or when matching bullet diameter closely to a particular firearm.

About the Lyman H&i Sizing Die .430

The Lyman H&i Sizing Die .430 is a dedicated bullet-sizing tool for reloaders working with cast bullets that need a finished diameter of .430. That makes it a natural fit for handgun and rifle applications where correct bullet fit is critical to accuracy, clean shooting and reliable lubrication. Rather than treating bullet sizing as a minor finishing step, this die supports one of the key adjustments in cast-bullet loading: bringing bullets to a consistent, usable diameter for the intended bore.

Its body sizing function keeps the tool focused and straightforward. For the handloader, that means less complication at the bench and a clear role within a cast-bullet workflow. The steel construction is appropriate for repeated use, while the standard 7/8"-14 thread helps it fit easily into common press setups without requiring a specialized mounting system. Because it is a single standard die, it also suits reloaders who need one exact diameter rather than a broader die set.

In practical use, a die like this matters because cast-bullet performance often depends on diameter as much as on alloy or lubricant choice. A properly sized bullet can help improve bore fit, support more even lubrication and reduce the variability that shows up on target. For reloaders already using Lyman bullet-casting equipment, the .430 H&i die is a simple, purpose-built component that keeps the sizing stage precise and repeatable.

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. Today, Lyman Products is headquartered in Middletown, Connecticut and focuses on equipment and accessories for shooting and reloading. Its range includes reloading dies, presses, bullet-casting equipment and gun sights, which gives the company a broad presence across the handloading bench as well as the firearm itself.

Lyman’s background in sight design remains part of its identity, and its tang and receiver sights still reflect principles from William Lyman’s original sight design. The company also expanded its reloading role through the 1925 acquisition of the Ideal reloading-tool business, a step that helped establish its long-standing place in this category. For products such as bullet-sizing dies, that history matters because Lyman’s tooling has been shaped by decades of practical reloading use rather than by a narrow single-product focus.
