Lyman Top Punch 658

• Bullet-Nose Matched Profile: The Lyman Top Punch 658 is machined to match the bullet nose shape, helping the lube/sizing press apply pressure evenly and reducing the risk of deforming cast bullets during sizing.
• Made for Lyman Lube/Sizing Equipment: Designed for use with Lyman bullet sizing systems, it gives reloaders the correct interface between bullet and press for smoother, more consistent operation.
• Steel Construction: The steel body stands up to repeated shop use and maintains its shape under pressure, which matters when processing larger batches of cast bullets.
• Useful for Cast-Bullet Reloading: As part of the bullet sizing process, the correct top punch helps preserve bullet form, which supports more uniform lubrication, sizing and finished ammunition quality.
• RCBS-Compatible Pattern: Lyman states that its top punches are interchangeable with RCBS, giving added flexibility for reloaders who already use compatible sizing equipment.

About the Lyman Accessories Series

The Lyman Accessories range covers the practical tools and small components that keep a reloading bench working efficiently. Within Lyman’s broader lineup, this series supports the company’s presses, dies, bullet-casting tools and case-preparation equipment with purpose-built parts designed for specific tasks rather than general use. That approach matters in cast-bullet reloading, where the fit between the bullet and the tool often determines whether the finished result stays uniform.

For bullet sizing and lubrication, the series includes components such as top punches and related sizing accessories that are matched to particular bullet forms. Their role is straightforward but important: they help the press contact the bullet correctly so the nose shape is not damaged during the sizing stroke. In practice, this makes the accessories series especially relevant to reloaders who cast their own bullets and want repeatable handling at the bench. The emphasis is on durable materials, compatibility with established Lyman equipment and a design philosophy centered on reliable workshop use rather than unnecessary complexity.

About the Lyman Top Punch 658

The Lyman Top Punch 658 is a specialized bullet sizing accessory made for cast-bullet reloaders who need the correct top-end contact point in a lube/sizing setup. Its main job is to fit the bullet nose shape closely enough that pressure from the press is applied without distorting the front of the bullet. That is a small detail in theory, but in practice it is important because a poorly matched punch can flatten or mark the nose during sizing, especially when working through multiple bullets in one session.

This model is part of Lyman’s long-established lube/sizing system and is intended for use where a specific punch number is called for. The benefit of using the correct punch is not only protection of bullet shape, but also a more controlled and repeatable sizing process. When the bullet sits properly under the punch, the press stroke feels more consistent and the finished bullet is better preserved for the next stages of loading. The steel construction supports repeated bench use, while the compact format makes it easy to keep as part of a dedicated cast-bullet setup. For reloaders focused on maintaining bullet form during sizing, Top Punch 658 is a simple but necessary tool component.

About Lyman

The Lyman Gun Sight Company began in 1878 in Middlefield, Connecticut, establishing a long connection with American shooting equipment. Today, Lyman Products is headquartered in Middletown, Connecticut and is known for making equipment and accessories for shooting and reloading. Its catalog spans reloading dies, presses, bullet-casting equipment and gun sights, which gives the brand a strong presence across both ammunition loading and firearm-support tools.

Lyman’s history 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 expanded its reloading footprint when it acquired the Ideal reloading-tool business in 1925, helping shape the broad product range it is known for today. That background is especially relevant for cast-bullet and reloading accessories, where Lyman remains closely associated with traditional bench equipment and practical workshop tools.
