I bought an Ideal 457483 385 grain Round Nose from Fleabay for a great buy. (to great maybe) I cleaned it down and started casting. Every time I opened the mold the boolit fell right out without tapping the mold screw. All seemed great until I saw the fins running up one side and the other. I cooled down the mold and checked for lead on the faces. I checked the alignment pins and their holes. I sanded all edges inside and out. I even turned over the handles. Not sure why. Nothing helped. Do we have someone on the forum that has the knowledge and equipment to figure this out? It is a discontinued mold from long ago and I sure would like to see it work again.
