Lyman Top Punch #658 Features The Lyman Top Punch #658 is precision machined to match the .457 inch bullet nose shape correctly a fit that matters because an improperly shaped punch can deform the bullet nose during the sizing and lubricating process. This particular punch is compatible with several Lyman bullet moulds including the 225 grain round nose #384-168 180 grain devastator hollow point #670-333 500 grain round nose #567-421 and 475 grain round nose gas check #471-527 among others. By matching the punch precisely to the bullet s nose profile reloaders can process cast bullets through their lube sizer with confidence that the shape and finish will remain consistent. This attention to fit is part of why Lyman top punches are trusted among serious bullet casters. Designed to fit both the Lyman 450/4500 lube sizer and the RCBS Lube-a-Matic-2 bullet sizer this top punch gives reloaders flexibility whether their bench is built around Lyman or RCBS equipment. Having the correct top punch on hand streamlines the lubricating and sizing workflow reducing wasted time and material from improperly sized bullets. For cast bullet reloaders working with .45 caliber projectiles having a dedicated top punch matched to the bullet profile is an important step toward consistent quality ammunition. The Lyman Top Punch #658 is available for sale at GrabAGun for reloaders casting their own .45 caliber bullets.
