I have several Lee aluminum molds and I have not been able to get decent boolits from any of them. And yes, I have tried every trick that has been thrown out there. I have used them bare and smoked. I have used beeswax and 2 stroke oil. Just today working with a brand new 45 caliber ACP mold I went from casting at 600 and went up 25 degrees at a time all the way to 850. This is with a 1-10 WW to pure alloy and this same alloy makes absolutely perfect boolits in several of my Lyman molds. The very last thing I tried in addition to using my hot plate to heat the molds was to dip the corner of the mold in the pot per Lee's instructions. Well, that got it hot enough that I had to wait quite a while for the lead to solidify and even then I had wrinkles and even worse I now had lead in the vent grooves and now the mold will not close all the way and I have flash at the joint. Tried to get it off with a wood dowell but it is stuck in there good so I am guessing this mold is trash now. Made probably 300 boolits and I will bet there is at least a 75% rejection rate. The other molds I have for 30 cal and 223 are no better. I am casting either straight linotype or 50/50 WW pure on them. Same end results. So does anyone know how to make them work? And is the one with the lead in the vent lines trash?
