Good morning gents! I haven't started to cast RBs yet, but have gathered most of the needed items. I purchased a few LEE molds (starting out I am cheap!), and a couple of RCBS molds. I also sprung for an adjustable clamping tension set of handles from ST Machining (through Desperado Cowboy Bullets) that fits all three major brands of mold blocks. My question is my newer LEE molds seem to have Type U Drive-in Threaded Pins (SKU: BM3042) to hold them onto the handles. The heads will accept a 3/ 32" Allen wrench, but I can't undo the pins. The holes the pins go into do not pass all the way through the blocks. Anybody ever removed those pins before? It looks like I may have to drill down from the top of the blocks on-center to the end of the pin and drive it out with a punch. An easier method would be appreciated! Thanks!
