Lyman Top Punch 374

• Bullet-Nose Fit: The Lyman Top Punch 374 is machined to match the bullet nose profile it is intended for, helping the lube-sizer press on the bullet correctly and reducing the risk of nose deformation during sizing and lubrication.
• Steel Construction: Its steel body stands up to repeated use in a reloading setup, giving consistent contact with cast bullets over long loading sessions.
• Made for Lube/Sizing Work: Built for bullet sizing and lubrication tasks, this top punch helps keep bullets aligned in the sizer so pressure is applied more evenly and finished bullets remain more uniform.
• Broad Casting Compatibility: Lyman top punches are designed for use with Lyman mould-related sizing equipment and are also noted as interchangeable with RCBS top punches, which is useful for reloaders working across mixed bench setups.
• Compact, Bench-Friendly Part: At 145.00 g, this accessory is easy to handle, store, and swap when changing bullet designs, making caliber or mould changes more straightforward at the loading bench.

About the Lyman Accessories Series

The Lyman Accessories range covers the small but essential components that keep a reloading and bullet-casting bench working smoothly. Within Lyman’s broader lineup of shooting and reloading equipment, these parts support the practical side of case preparation, bullet sizing, lubrication, and general bench work. Rather than adding complexity, the series focuses on fit, repeatability, and compatibility, which are the qualities that matter most when a reloader wants uniform results from one batch to the next.

In the bullet-casting segment, Lyman accessories are built to work with the company’s long-established lube and sizing tools. Parts such as top punches are shaped for specific bullet profiles so the bullet can be guided through the sizing process with less risk of damage. That matters especially to cast-bullet shooters who want to preserve bullet form for dependable seating, lubrication, and downrange consistency. Across the series, the design philosophy is straightforward: durable materials, simple function, and dependable integration with established Lyman equipment used by handloaders and cast-bullet shooters.

About the Lyman Top Punch 374

The Lyman Top Punch 374 is a purpose-built accessory for cast-bullet sizing setups, intended to contact the bullet nose correctly during the lubrication and sizing process. In this role, the exact shape of the top punch matters because the force applied by the press is transferred through this small part. By matching the bullet nose profile it is designed for, the Top Punch 374 helps the bullet enter the die more squarely and with less chance of flattening or marking the nose. For reloaders working with cast bullets, that is a practical advantage because it helps preserve bullet shape and supports more consistent finished ammunition.

Its steel construction suits repeated bench use, where accessories are installed, removed, and swapped as bullet designs change. The part is also compact and straightforward to handle, which makes it easy to keep organized alongside sizing dies and mould-related tools. As part of a bullet-sizing workflow, it is less about adding features and more about improving the quality of the process: better support on the bullet, smoother operation in the sizer, and less risk of cosmetic or functional damage to cast projectiles. For handloaders using Lyman lube/sizing equipment, the Top Punch 374 is a simple but important component in producing properly sized and lubricated cast bullets.

About Lyman

The Lyman Gun Sight Company began in 1878 in Middlefield, Connecticut, giving the brand a long history in shooting equipment. Over time, Lyman expanded from sighting products into a broader range of tools for shooters and reloaders, and it remains closely associated with practical bench equipment and cast-bullet work. The company later strengthened its reloading position when it acquired the Ideal reloading-tool business in 1925, linking the Lyman name with handloading for generations.

Today, Lyman Products is headquartered in Middletown, Connecticut and makes equipment and accessories for shooting and reloading. Its product lines include reloading dies, presses, bullet-casting equipment, and gun sights, which explains why the brand remains well known among reloaders who want compatible tools across the entire loading process.
