Lyman H&i Sizing Die .285

• Precision bullet sizing: The .285 H&I die brings cast bullets to a consistent final diameter, which helps support uniform bore fit and more repeatable accuracy.
• Body sizing design: This die is made for the sizing stage itself, giving reloaders a straightforward way to control bullet diameter before lubrication and loading.
• Hardened steel construction: The steel sizing surface resists wear in regular workshop use, helping the die maintain its dimensions over time.
• Tapered entry for alignment: Lyman’s H&I sizing dies use a tapered mouth to guide the bullet into the die more smoothly, supporting straighter entry and a more uniform cylindrical shape.
• Made for standard equipment: With standard 7/8"-14 thread compatibility, the die fits common reloading setups without requiring a special press interface.

About the H&I Sizing Die Series

Lyman H&I Sizing Dies are part of the company’s long-established bullet-casting and cast-bullet reloading range. They are intended for reloaders who cast their own bullets and want a controlled, repeatable way to bring bullet diameter to the correct finished size before use. In Lyman’s lineup, these dies sit alongside the brand’s lubricating and sizing tools, giving handloaders a practical system for cast-bullet preparation rather than cartridge-case sizing.

The series is built around a simple mechanical idea: a hardened sizing die with a tapered mouth for easier bullet entry and an interior dimension matched to a specific finished diameter. Lyman also uses 90° hole spacing in the improved H&I design to aid bullet lubrication, including with harder lubricants. This makes the series especially relevant for reloaders who want consistent bullet shape, reliable lubricant distribution, and compatibility with established cast-bullet workflows. The result is a durable, workshop-focused tool family designed for accuracy-minded bullet casters rather than general-purpose die sets.

About the Lyman H&i Sizing Die .285

The Lyman H&i Sizing Die .285 is a single-purpose bullet sizing die for reloaders working with cast bullets that need a .285 final diameter. In cast-bullet loading, correct bullet fit is critical: a bullet that is too large may chamber poorly, while one that is too small can reduce consistency in the bore. By sizing bullets to a controlled diameter, this die helps support more uniform loading results and steadier on-target performance.

Its body sizing function keeps the tool focused on one job, which is often exactly what experienced handloaders want when building a dedicated casting setup. The steel construction is suited to repeated bench use, while the tapered die mouth helps guide bullets into the sizing section with better alignment. In practice, that matters because straighter entry can help preserve bullet form and produce a more even cylindrical result. The die is also built for standard 7/8"-14 thread compatibility, so it integrates easily into common reloading equipment layouts. For bullet casters using Lyman lubricating and sizing equipment, this .285 die is a straightforward way to match bullet diameter to a specific application without adding unnecessary complexity.

About Lyman

The Lyman Gun Sight Company began in 1878 in Middlefield, Connecticut, and the brand has remained closely tied to practical shooting equipment ever since. Lyman Products is headquartered in Middletown, Connecticut, and the company is known for making equipment and accessories for shooting and reloading. Its range covers reloading dies, presses, bullet-casting equipment, and gun sights, which gives the brand a broad presence across both ammunition preparation and firearm support gear.

A key step in that development came in 1925, when Lyman acquired the Ideal reloading-tool business. That helped establish the company as a long-standing name in handloading tools as well as sights. For reloaders and cast-bullet shooters, Lyman’s reputation rests on durable bench equipment, practical designs, and a product catalog that supports the full workflow from casting and sizing to loading.
