Lyman Top Punch 359

• Bullet-Nose Matched Fit: The Lyman Top Punch 359 is made to match the bullet nose profile correctly, helping the sizing and lubricating process apply pressure where it should and reducing the risk of deforming the nose.
• Supports Cleaner Sizing Work: In bullet sizing setups, a properly matched top punch keeps the bullet aligned more consistently, which helps maintain bullet shape and supports more uniform finished results.
• Steel Construction: The steel body is suited to repeated workshop use, giving this bullet sizing accessory the durability needed for regular casting and reloading sessions.
• Made for Lyman Lube/Sizing Equipment: As part of Lyman’s bullet-casting system, this top punch integrates into established sizing workflows and is intended for reloaders who want the correct punch for a specific bullet profile.
• RCBS Interchangeability: Lyman states that its top punches are interchangeable with RCBS, which is useful for reloaders working with compatible equipment across different bench setups.

About the Lyman Accessories Series

The Lyman Accessories range covers the supporting tools and components that keep a reloading or bullet-casting bench working efficiently. Rather than focusing on one single machine, the series includes the small but important parts that allow reloaders to adapt equipment to specific bullets, cases, and tasks. In practical terms, that means accessories built to fit into established workflows for case preparation, bullet sizing, lubrication, and related bench work.

Within Lyman’s broader reloading lineup, this series serves users who want purpose-built components instead of general substitutes. The emphasis is on straightforward function, durable materials, and compatibility with Lyman equipment used for casting and sizing. For bullet-casting applications in particular, accessories such as top punches matter because they help the press contact the bullet correctly during sizing. That approach reflects the series as a whole: simple, task-specific tools that support repeatable results, reduce avoidable damage to components, and make bench work more consistent for reloaders who already know the value of using the right part for the job.

About the Lyman Top Punch 359

The Lyman Top Punch 359 is a dedicated bullet sizing accessory intended for use in Lyman lube/sizing equipment. Its job is simple but important: it contacts the bullet from above during the sizing process, and its shape is designed to fit the bullet nose correctly. That proper fit matters because it helps prevent pressure from being applied unevenly across the nose, which can otherwise mark or deform the bullet during sizing and lubrication.

For reloaders and bullet casters, that translates into a more controlled workflow. A top punch that matches the bullet profile helps the bullet sit and travel more consistently through the sizing operation, which supports better finished bullet shape and reduces the chance of cosmetic or functional damage. This is especially relevant when working with cast bullets where nose form should be preserved as closely as possible.

The part is made from steel, giving it the durability expected from a bench accessory that may be installed, removed, and reused many times. With a listed weight of 145.00 g, it is a compact workshop component rather than a general-purpose tool, but it plays a specific role in keeping bullet sizing setups properly configured. Lyman also notes that its top punches are interchangeable with RCBS, which adds flexibility for reloaders using compatible presses or mixed bench equipment.

About Lyman

The Lyman Gun Sight Company began in 1878 in Middlefield, Connecticut, establishing a long history in shooting equipment. Over time, the company expanded beyond sights into a broader range of tools for reloaders and shooters, and Lyman acquired the Ideal reloading-tool business in 1925, an important step in building its reloading portfolio. Today, Lyman Products is headquartered in Middletown, Connecticut and is known for making equipment and accessories for shooting and reloading.

Its catalog covers practical bench and field equipment, including reloading dies, presses, bullet-casting equipment, and gun sights. That background is especially relevant for products such as bullet sizing accessories, where the company’s long involvement in casting and reloading tools shows in the focus on fit, compatibility, and straightforward workshop function.
