Lyman Top Punch 43

• Bullet-Nose Support: The Lyman Top Punch 43 is machined to match the bullet nose profile, so the bullet is supported correctly during sizing and lubrication. That helps reduce nose deformation and keeps cast bullets closer to their intended shape.
• Cleaner Sizing Operation: Used with Lyman lube/sizing equipment, this top punch helps apply pressure evenly from the top of the bullet. In practice, that makes the sizing stroke more controlled and helps maintain consistent results from one bullet to the next.
• Steel Construction: The steel body gives this bullet sizing accessory the durability needed for repeated bench use. It stands up well to the pressure involved in cast-bullet sizing and lubrication work.
• Model-Specific Fit: As Top Punch 43, this version is intended for bullet designs that call for that punch number. Choosing the correct punch improves alignment in the sizer and helps protect bullet shape during reloading work.
• Made in USA: Built in the USA, this accessory follows Lyman’s long-established approach to reloading tools and cast-bullet equipment, making it a practical match for reloaders already using the brand’s sizing system.

About the Lyman Accessories Series

The Lyman Accessories range covers the small but essential tools that keep a reloading bench working efficiently. Within Lyman’s broader lineup of casting and reloading equipment, this series supports the practical steps that come before and after the main loading process, including case preparation, bullet casting and bullet sizing. These parts are aimed at reloaders who want repeatable results and who understand that consistency often depends on using the correct accessory for each task.

In the cast-bullet segment, Lyman’s accessory line is closely tied to the company’s long-running sizing and lubrication equipment. Items such as top punches and related components are designed to work as part of a complete system rather than as generic bench hardware. The emphasis is on proper fit, durable materials and straightforward function. For bullet casters, that matters because the right accessory helps preserve bullet shape, supports smoother operation in the press and reduces avoidable variation during sizing. The series is therefore especially relevant to shooters and reloaders who build ammunition around cast bullets and want dependable, purpose-built tooling.

About the Lyman Top Punch 43

The Lyman Top Punch 43 is a specialized bullet sizing accessory made for use in cast-bullet reloading setups. Its job is simple but important: it contacts the bullet from above during the sizing and lubrication process, and it does so in a way that matches the bullet nose profile more closely than a flat or improvised contact surface would. That support helps the bullet enter the sizing die with better alignment and lowers the chance of distorting the nose under pressure.

For reloaders working with cast bullets, that practical benefit matters because bullet shape influences feeding, consistency and downrange behavior. A correctly matched top punch helps preserve the form created by the mould, which is especially useful when the goal is uniform ammunition rather than just basic function. Precisely machined and made from steel, this model is built for repeated use at the loading bench and fits naturally into Lyman’s established lube/sizer workflow.

Top Punch 43 is also part of a numbered system, so it is chosen according to the bullet design being used. That makes it a task-specific accessory rather than a one-size-fits-all part. For cast-bullet shooters who already rely on Lyman sizing equipment, this model provides the correct upper contact point needed for smoother operation and better protection of bullet geometry during sizing and lubrication.

About Lyman

Lyman began as the Lyman Gun Sight Company in 1878 in Middlefield, Connecticut. Over time, the company expanded from sight-making into a broader role in shooting and reloading equipment, and it remains closely associated with practical tools for handloaders and cast-bullet shooters. One important step in that development came in 1925, when Lyman acquired the Ideal reloading-tool business, strengthening its position in the reloading market.

Today, Lyman Products is headquartered in Middletown, Connecticut and produces equipment and accessories for shooting and reloading. Its range includes reloading dies, presses, bullet-casting equipment and gun sights, which makes the brand particularly relevant to reloaders who want related tools from one established maker. That long involvement in both sighting products and bench equipment helps explain why Lyman remains a familiar name in cast-bullet and reloading circles.
