You guys that are having trouble getting a mold to pour...This is what I do I leave my mold on top of my lead pot, for atleast 15-20 min after the lead is melted. Get it god and HOT! If its a barbed collar mold slightly tilt it alittle to allow air to seep out..( learned this from REDMAN)... Hope this helps..Myself I pour thousands of jigheads a mth. And it works.
