While rooting through and cleaning up my makeshift loading room in hopes that for my 120th birthday I could finish it into my perfect room just off the master bedroom here I've been coming across so old paperwork,catalog, flyers etc. One is a very old set of instructions that came with a Hensley and Gibbs molds. They mention that when using their bigger molds and if you get it running to hot.....While leaving the bullets in the cavity....plunge the mold into a bucket of hot water for a couple seconds. This will help you maintain temperature of the mold. After all you've heard about water around your molten lead it sounds a little spooky doesn't it?....lol. I just found it interesting and I haven't dunked any molds yet.
