Lyman Top Punch #251 (.43 Round Nose)

The Lyman Top Punch #251 (Lyman part no. 2786704) is the caliber and profile-specific punch that seats a .43 Round Nose cast bullet squarely in a lubricator-sizer without deforming its nose. Lyman machines each top punch to match a specific bullet nose shape, so the punch face contacts only the flat or ogive it is meant for instead of crushing a rounded tip or hollow point. It threads into the Lyman 450/4500 lubrisizer as well as the RCBS Lube-A-Matic-2, making it a direct add-on for casters who pick up a new mould and need the matching punch. Find it filed with our reloading equipment selection.
