Top Punches for Bullet Sizing

A Top Punch is a crucial component when sizing and lubricating cast bullets using tools like the Lyman 4500 or RCBS Lube-A-Matic. Its purpose is to press the bullet into the sizing die without deforming the tip, thanks to a shape-matched cavity. Each top punch is designed to match specific bullet profiles—round nose, flat point, semi-wadcutter, hollow point—ensuring perfect alignment and avoiding damage during the sizing process. This preserves bullet integrity and improves shooting accuracy. We carry top punches compatible with molds from Lyman, RCBS, Saeco, NOE, and others. If you cast and size your own bullets, using the correct top punch is essential for consistent, professional results.
