RCBS Lube-A-Matic Top Punch .638

The RCBS Lube-A-Matic Top Punch .638 is a precision reloading component designed for serious handloaders seeking to eliminate nose deformation on cast and swaged bullets. This top punch assembly integrates seamlessly with RCBS Lube-A-Matic equipment to deliver consistent, repeatable results across high-volume production runs or careful single-stage reloading. Whether you're loading for pistol or rifle applications, this punch ensures your projectiles maintain proper geometry for optimal chamber fit and ballistic performance.

Engineered from quality materials with meticulous craftsmanship, the .638-inch diameter punch is specifically machined to prevent the deformation issues commonly encountered with conventional sizing dies. The precision-ground contact surface distributes compressive force evenly across the bullet nose, protecting soft lead cores and plated surfaces from unsightly flattening or marring. RCBS's proven manufacturing standards ensure dimensional accuracy and durability, allowing the punch to maintain performance across thousands of reloading cycles without wear or drift.

Reloaders who prioritize consistent ammunition quality—particularly those working with cast bullets, lead-free projectiles, or match-grade rifle rounds—will benefit from this punch's superior nose protection. The .638-inch specification accommodates a wide range of bullet diameters commonly encountered in handloading. Installation is straightforward on compatible Lube-A-Matic equipment, making this a cost-effective upgrade for anyone looking to reduce bullet waste and improve finished-round consistency.
