Lyman Top Punch 413

• Bullet-Nose Fit: The Lyman Top Punch 413 is machined to match the bullet nose profile, helping the lube-sizer apply pressure evenly and reducing the risk of deforming cast bullets during sizing.
• Built for Lube/Sizing Work: Designed for bullet sizing and case-preparation bench use, it supports smoother operation in manual casting and sizing workflows where consistent bullet shape matters.
• Steel Construction: Its steel body stands up to repeated contact and bench use, giving reloaders a durable accessory for regular cast-bullet production.
• Model-Specific Selection: The 413 profile is part of Lyman’s numbered top-punch system, making it easier to match the correct punch to a compatible bullet mould and maintain proper bullet alignment.
• RCBS Interchangeability: Lyman states these top punches are interchangeable with RCBS, which is useful for reloaders working with mixed casting equipment on the same bench.

About the Lyman Accessories Series

Lyman Accessories covers the small but essential bench components that keep a reloading or bullet-casting setup working correctly. Within Lyman’s broader lineup of reloading tools, these parts support the practical side of handloading: setup, case preparation, bullet casting, sizing and lubrication. Rather than being general-purpose add-ons, they are typically made for a specific task, which helps the user maintain repeatable results across long loading sessions.

In the bullet-casting segment, the series includes parts that work with Lyman lube/sizing equipment and related tooling. Items such as top punches and sizing dies are chosen to match a particular bullet design or diameter, so the system can size and lubricate cast bullets without unnecessary distortion. That approach reflects the design philosophy behind the series: simple mechanical parts, precise fit and bench durability. For reloaders who cast their own bullets, these accessories matter because they help preserve bullet shape, support consistent lubrication and keep the sizing process predictable from one batch to the next.

About the Lyman Top Punch 413

The Lyman Top Punch 413 is a model-specific accessory for cast-bullet sizing, intended for use with Lyman lube/sizing equipment. Its job is straightforward but important: it contacts the bullet nose during the sizing process, so the shape of the punch needs to match the bullet profile as closely as possible. When that fit is correct, pressure is applied more evenly and the bullet is less likely to suffer nose deformation while being pushed through the sizing die.

That makes the Top Punch 413 particularly relevant to reloaders who want to maintain the intended shape of a cast bullet during post-casting operations. In practical terms, preserving the nose profile helps keep finished bullets uniform, which is valuable when loading for accuracy, repeatable seating characteristics and clean handling at the bench. Lyman describes its top punches as precisely machined, and that precision is the main reason this type of accessory matters: even a small mismatch at the contact point can mark or distort softer cast bullets.

The part is made from steel and weighs 145.00 g, giving it the durability expected from a bench accessory that sees repeated use. Lyman also notes that its top punches are interchangeable with RCBS, which can be useful for reloaders who already have compatible equipment and want to integrate this punch into an existing cast-bullet workflow.

About Lyman

The Lyman Gun Sight Company began in 1878 in Middlefield, Connecticut, and the brand has long been associated with practical tools for shooters and reloaders. Lyman Products is headquartered in Middletown, Connecticut, and its catalog focuses on equipment for reloading, bullet casting and shooting support. Over time, the company expanded beyond sights into a broad range of bench tools and accessories used by handloaders.

Lyman acquired the Ideal reloading-tool business in 1925, a step that helped establish its place in the reloading market. Its product lines include reloading dies, presses, bullet-casting equipment and gun sights, which makes the brand especially relevant to reloaders who want related tools from one maker. That long involvement in cast-bullet and reloading equipment is what gives Lyman products, including small bench accessories such as top punches, their practical reputation.
