Lyman Top Punch #402 .9mm/.38 Conical

The Lyman Top Punch #402 .9mm/.38 Conical is a precision-engineered reloading component designed for handloaders who demand consistency and accuracy in their ammunition assembly. This conical punch works in conjunction with Lyman bullet moulds to shape and finish projectiles with controlled nose geometry, eliminating the dimensional variation that can result from manual pressing or improper tooling. For reloaders focused on quality ammunition production, this punch represents a critical investment in dimensional control and shot-to-shot consistency.

Lyman precision-machines all top punches to exact tolerances that match the nose profile of their corresponding bullet moulds. This precision fit prevents deformation, flattening, or asymmetrical shaping of the bullet nose during the swaging process—critical for rounds where consistent ogive geometry affects ballistic performance and chamber fit. The .9mm/.38 conical configuration is optimized for mid-range calibers, providing the proper nose radius and depth control required for reliable functioning in standard firearms. The compact design (2.35 x 1.2 x 4.45 inches) integrates seamlessly into Lyman press setups without requiring additional adapters or modifications.

Serious handloaders—whether developing match-grade pistol loads, preparing duty-grade ammunition, or maintaining consistent performance across high-volume production—rely on matched tooling sets like this punch to maintain quality standards. This component pairs with Lyman's extensive moulds catalog to enable complete control over projectile dimensions and nose geometry. For those building ammunition for precision pistol competitions, law enforcement qualification courses, or defensive carry applications, matching your punch to your mould ensures repeatability that loose or worn punches cannot achieve.
