My new MP 40 cal mold arrived a few days ago so I set up my casting table and melted a pot of lead this afternoon
anticipating a pile of 165 gr boolits. Never in my life have I worked for so long and unable to get one good pour or even any usable boolits. Extremely frustrating. Received new Saeco 9mm mold a few weeks ago and had a very productive session yielding about 550 good boolits. Today was the first time I have used a 6 cavity mold. Thought I was about to get the hang of it when my Pro Melt pour spout started acting up. Had to use a paper clip to unclog it about every pour. So I gave up and emptied the pot so I could clean it out. After it was emptied, could not find a reason for the clogging. Going to try again another day. Here is a pic of the only boolits that did not go back into the pot and none of these are good.
Afterthought: I had my pot set on 750, which worked great for the iron mold. Maybe I need to run the temp higher with this aluminum mold. Just started casting again after an estimated 20 year hiatus.
