I believe NEI has some good designs in .475 as well. Might check their online catalog. As for LBT, he's easy to contact - look a couple of lines below this forum and he's there. As for Lee, I'd send that mould back anyway. I just sent back a terribly out of round 45-70 mould and got back one that is perfect. They paid postage from their end, so it was just a couple of bucks to get a good mould instead of throwing away the one I had. They were very helpful and even called to make sure I am happy with my new one.
