Picked up a cheap ($40 shipped) DC mold off another site. No rust but someone had managed to bend the sprue plate and there were specks of lead on the faces as well as on top. Cleaned it up and did a little blacksmith work on the plate and removed a burr on the edge that was gouging the top of the mold and it fits fine now. Amazes me how people can abuse molds and expect to get decent bullets out of them.
