Lyman H&i Sizing Die .264

• .264 sizing diameter: brings cast bullets to a consistent 6.71 mm / .264 diameter, which helps match bullet fit to the bore for more uniform accuracy and cleaner performance.
• Body sizing operation: this H&I die is built to size the bullet body in the lubricator-sizer, making it a practical choice for reloaders who want repeatable finished bullet dimensions.
• Hardened steel construction: the steel sizing die resists wear in regular bench use, so it maintains its internal dimensions over time and supports consistent results across many batches.
• Tapered, alignment-focused design: Lyman’s H&I sizing dies use a tapered mouth and hardened interior to help guide bullets into the die smoothly and preserve a true cylindrical shape during sizing.
• Standard fit and broad compatibility: the die works with standard 7/8"-14 threaded press setups and is interchangeable with RCBS-style H&I sizing dies, which makes it easy to integrate into an existing casting bench.

About the H&I Sizing Dies Series

Lyman H&I Sizing Dies are part of the company’s long-established bullet-casting and reloading range, aimed at reloaders who cast their own bullets and want precise control over final bullet diameter. In Lyman’s lineup, these dies sit alongside lubricator-sizer equipment and related casting tools, forming a practical system for finishing cast bullets before loading. Their role is straightforward but important: they size bullets to the intended diameter while supporting proper alignment in the lubricating and sizing process.

The series is built around a hardened interior, a tapered mouth, and 90° hole spacing for easier bullet lubrication, including use with harder lubricants. In practice, that means smoother bullet entry, more consistent cylindrical form, and easier handling at the bench. The H&I format is especially relevant for reloaders tuning cast bullets for specific rifle or pistol calibers, where bullet fit has a direct effect on accuracy, fouling control, and reliable downrange performance. Rather than serving as a general-purpose loading die, this series is designed specifically for the finishing stage of cast-bullet preparation.

About the Lyman H&i Sizing Die .264

The Lyman H&i Sizing Die .264 is intended for cast-bullet reloaders who need a finished bullet diameter of 6.71 mm / .264. That makes it relevant for .264-caliber and 6.5 mm applications where correct bullet fit is a key part of obtaining stable accuracy and controlled leading. In cast-bullet work, even small diameter differences matter, so a dedicated sizing die like this gives the reloader a more repeatable way to finish bullets for a specific bore requirement.

This is a single standard H&I body sizing die made from steel and configured for standard adjustment. Its purpose is not to perform multiple loading steps, but to do one job consistently inside the lubricator-sizer workflow: bring the bullet body to the target diameter while maintaining shape. That focused design is useful for reloaders who sort loads by firearm, alloy, or intended velocity and want each batch finished to the same dimension.

Because it follows the established H&I pattern, the die fits naturally into a cast-bullet bench setup and supports efficient caliber-specific work. The practical advantage is consistency: bullets that enter the seating and loading stages with the intended diameter are easier to manage, and they give the handloader a better foundation for accuracy testing, lubrication performance, and repeatable results on the range.

About Lyman

The Lyman Gun Sight Company began in 1878 in Middlefield, Connecticut, and the business has long been associated with practical tools for shooters and reloaders. Lyman Products is headquartered in Middletown, Connecticut, and its core focus includes reloading equipment, bullet-casting tools, and gun sights. That background is especially relevant in products like sizing dies, where bench precision and long-term usability matter more than cosmetic design.

Over time, Lyman expanded its reloading portfolio through both in-house development and acquisitions. Lyman acquired the Ideal reloading-tool business in 1925, helping establish its place in the American reloading market. Its catalog today spans dies, presses, casting equipment, and related accessories, reflecting a long specialization in the tools used to build and refine handloaded ammunition.
