So i cast hollow base bullets for 41 Long colt, Lyman 12 gauge slug and a 58 minie bullet for a muzzle loader. Until the base plug heats up, one gets a lot of rejects but once it does, it’s usually smooth sailing. So I thought. I just got the above mold at a gun show and it’s recommended for cap n ball revolvers. It’s only a 155 grain bullet. I probably cast about 120 slugs to only have about 18 that are usable. The skirt wouldn’t fill out. I tried heating the base plug with a lighter and that maybe worked for 1 good casting. The closest I got to make 3 or 4 good castings in a row was to turn my lee pro 1000 at full setting where it may or may not have cycled on/off. It was so hot the base was glowing like an electric stove. So this mold is new enough to have the air vents.
Any thoughts how I can get it to work? It must have worked at one time or Lyman would not have made it. I first tried really soft stick on wheel weights, then added a bit of harder clip on wheel weights then even put in some 50/50 lead/tin. No help.
