I ordered a new Lee .452 228gr. mold a few days ago and recieved it today.I was quite surprized to find that it looked quite different from previously aquired lee molds in that it had screws holding the handles on and tapered pins for lining the blocks up. Is this a design that has been around for a while or is it something new. will all Lee molds be this design from now on. I havn't used the mold yet but it looks much improved.
