A while back I bought a 2 cavity Lyman 452374 on eBay. It didn't look too great but I wanted a LRN mould for my 1911's so I took a chance. When it arrived, it still looked like it had been stored out in the weather but at least the cavities appeared smooth. A couple of days ago I got a chance to cast and didn't pay too much attention to the bullets as my Lyman bottom pour pot was clogging and giving me fits. I ended up using a ladle! Anyway, that evening as I got ready to size and lube them I realized that grubby old mould produces some of the most perfectly round and smooth bullets of any of my moulds. Now I can't wait to cast again. I'm as happy as a puppy with a new ball! Don't be afraid to take a chance on those old moulds.
