Lyman H&i Sizing Die .356

• .356 sizing diameter: Sizes cast bullets to .356 for common 9 mm and similar applications, helping maintain consistent bullet fit for better accuracy and more uniform results on target.
• Body sizing operation: This die is built specifically for bullet body sizing, giving reloaders a straightforward way to bring cast bullets to the intended diameter before lubrication or loading.
• Steel construction: A steel sizing die stands up well to repeated use on the loading bench and keeps its working dimensions stable over time, which matters when producing uniform batches.
• Standard 7/8"-14 thread: The standard thread pattern fits common presses, making it easy to integrate into an existing reloading setup without special adapters.
• Made in USA: Domestic manufacture is a practical advantage for reloaders who value established production standards and easier continuity within a long-term bench setup.

About the H&i Sizing Die 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 tighter control over final bullet diameter. In Lyman’s lineup, these dies sit alongside lubricating and sizing equipment used to prepare cast bullets for consistent loading, especially where bullet fit to the bore is a key part of accuracy and clean performance.

The series is built around a simple purpose: bring a cast bullet to a precise finished diameter while supporting uniform shape through the sizing process. That makes these dies particularly relevant for handgun and rifle reloaders working with home-cast projectiles, where small diameter differences can affect chambering, leading and downrange consistency. Steel construction, a standard press-compatible format, and caliber-specific sizing options make the H&i range practical for reloaders who want a dedicated die for a particular bullet diameter rather than a one-size-fits-all approach. Within Lyman’s casting tools, the series is valued for straightforward operation, repeatable results, and compatibility with established bench equipment.

About the Lyman H&i Sizing Die .356

The Lyman H&i Sizing Die .356 is a single body sizing die made for reloaders who need cast bullets finished to .356. That diameter is especially relevant for many 9 mm and similar handgun bullet applications, where correct bullet fit plays a major role in balancing accuracy, reliable chambering, and controlled fouling. By sizing bullets to a consistent final diameter before loading, this die helps produce ammunition with more uniform ballistic behavior from round to round.

Its steel construction is well suited to repeated bench use, giving the die the durability needed for regular casting and reloading sessions. The standard adjustment format keeps setup familiar, which is useful when changing between dies or integrating it into an established workflow. Because it uses a standard 7/8"-14 thread, it fits the common press pattern used on many reloading benches, so it can be added without changing the rest of the setup.

As a single standard die, this model suits reloaders who already know the exact bullet diameter they want and prefer a dedicated tool for that task. In practice, that means less compromise when preparing cast bullets for consistent seating, dependable fit, and predictable performance on the range.

About Lyman

The Lyman Gun Sight Company began in 1878 in Middlefield, Connecticut, establishing the brand early in the American shooting market. Over time, Lyman expanded from sight-making into a broader reloading and shooting-equipment business, and in 1925 it acquired the Ideal reloading-tool business, a step that helped shape its long-standing place in handloading.

Today, Lyman Products is headquartered in Middletown, Connecticut and is known for equipment and accessories for shooting and reloading. Its range includes reloading dies, presses, bullet-casting equipment, and gun sights, reflecting a strong focus on practical bench tools for shooters who assemble their own ammunition. That background makes Lyman especially relevant in categories such as bullet sizing, where consistency, mechanical simplicity, and repeatable setup matter more than unnecessary complexity.
