I was at a gunshow and saw an Ideal 311 8 (not 31108 or 311008) single cavity bullet mould on a table. It was reasonably priced. There was a little light surface rust on the outside of the mould. There was a little more rust and light pitting on one side (probably the side down when it was stored) However, the cavity was in good shape and the two halves closed tightly. I bought it.
When I got home, I took it apart for cleaning and fitting like I do with all my moulds, new or old. It was then I saw the matching numbers on each side. They were 666. Now I know the Devil shoots a 32-20. Or did.
