I've used Lee, Lyman and RCBS molds, but I'm totally sold on a couple of offerings from Accurate Molds, especially one designed by the late Jack Kort (43-215C). I urge you to consider investing in one of those molds. The bullets work very well in all five of my 44 WCF guns. A quick search here will yield volumes of information. In fact, read the top sticky thread in this forum and you'll read about Jack's journey with my all-time favorite cartridge. He was a fantastic man and a wealth of information.
