RCBS Lube-A-Matic Top Punch .635

The RCBS Lube-A-Matic Top Punch .635 is a precision reloading component designed to eliminate nose deformation when processing cast or swaged bullets through a bullet sizer lubricator. This .635-inch top punch is engineered to work with the RCBS Lube-A-Matic sizer or Lyman 450/4500 lube-sizing equipment, making it an essential tool for handloaders who demand consistent, undamaged bullet profiles across production runs.

Manufactured from quality materials with precision machining, this top punch is machined to match bullet nose geometry exactly. The .635-inch diameter specification fits mid-range projectiles commonly used in popular pistol and revolver cartridges. Unlike flat or generic punches that compress bullet tips, this shaped punch distributes pressure evenly across the nose, preserving bullet integrity and promoting reliable feeding and consistent ballistics downrange. The compact dimensions (2.05 x 0.5 x 2.85 inches) keep the component lightweight and easy to integrate into existing reloading setups.

This punch serves serious handloaders and reloading enthusiasts who process volume quantities of ammunition at home. Whether you're loading for competition shooting, hunting, or general practice, bullet nose deformation can negatively affect velocity consistency and impact accuracy. By maintaining true bullet profile through the sizing process, the RCBS Lube-A-Matic Top Punch .635 supports tighter shot groups and more predictable performance. The punch's affordability makes it accessible to budget-conscious reloaders without compromising dimensional accuracy or build quality—a hallmark of RCBS reloading equipment design.
