Lyman Top Punch 311

• Bullet-Nose Matched Profile: The Lyman Top Punch 311 is machined to match the bullet nose shape, helping the bullet stay properly supported during sizing and lubrication so the nose is not flattened or distorted.
• Better Bullet Alignment: A correctly fitted top punch keeps pressure centered on the bullet, which supports more consistent handling in the sizer and helps maintain uniform finished bullet shape.
• Steel Construction: The steel body stands up to repeated bench use and provides the rigidity needed for precise contact with cast bullets during routine reloading work.
• Made for Lube/Sizing Work: Built for bullet sizing and case-preparation bench setups, this accessory supports smooth operation when loading cast bullets for regular range use or higher-volume reloading sessions.
• RCBS Interchangeability: Its interchangeable fit with RCBS top punch systems adds flexibility for reloaders who use mixed equipment on the bench.

About the Lyman Accessories Series

The Lyman Accessories series covers the small but essential bench components that keep reloading and bullet-casting equipment working efficiently. Within Lyman’s lineup, these parts support the company’s broader range of presses, dies, casting tools and lube/sizing equipment, giving reloaders a way to configure their setup for specific cartridges and bullet designs. Rather than focusing on one complete tool, the series is built around the idea that precision handloading depends on the correct interface between the tool and the component being worked on.

For cast-bullet users, that matters in practical terms. Accessories such as top punches, sizing dies and related bench parts help preserve bullet shape, maintain alignment and reduce the chance of damage during sizing and lubrication. The design philosophy is straightforward: simple, durable steel components, made for repeated workshop use, with dimensions matched to the task they perform. In that role, the series appeals to handloaders who want dependable bench hardware for routine production as well as careful load development, especially when working with cast bullets where fit and shape directly affect finished results.

About the Lyman Top Punch 311

The Lyman Top Punch 311 is a purpose-built accessory for cast-bullet sizing, designed to contact the bullet nose with the correct profile during use in Lyman lube/sizing equipment. Its main advantage is practical rather than complicated: when the top punch matches the bullet nose shape properly, pressure is applied more evenly and the bullet is less likely to suffer nose deformation. That helps preserve the form of the cast bullet while it is being sized and lubricated, which is especially important for reloaders who want consistent finished projectiles.

Because this model is part of Lyman’s numbered top punch range, the 311 profile is intended for bullet designs that call for that specific nose fit. In use, that means better support at the point of contact and more controlled movement through the sizing process. The result is a cleaner workflow on the bench and less risk of marring bullets that have already been cast carefully.

The accessory is made from steel and manufactured in the USA, giving it the durability expected from a frequently handled bench component. Its compact form and straightforward function make it easy to integrate into an established bullet-sizing setup. For reloaders using compatible Lyman mould recommendations, or mixed setups that benefit from RCBS interchangeability, the Top Punch 311 is a simple but important part of maintaining bullet shape and consistency during cast-bullet preparation.

About Lyman

The Lyman Gun Sight Company began in 1878 in Middlefield, Connecticut, and the brand has long been associated with practical equipment for shooters and reloaders. Lyman makes equipment and accessories for shooting and reloading, with product lines that include reloading dies, presses, bullet-casting equipment and gun sights. That broad focus helps explain why the company remains closely tied to bench tools and components used in day-to-day handloading work.

Lyman Products is headquartered in Middletown, Connecticut, and its history in reloading was expanded further when it acquired the Ideal reloading-tool business in 1925. The company’s long presence in casting and reloading equipment is especially relevant to products such as bullet-sizing accessories, where practical fit, repeatable function and compatibility across established tool systems matter more than unnecessary complexity.
