That's what I was thinking. Kind of a ridiculous post. So 45/70.gov, what happened after that drop? Did you stop casting? Did it keep doing it? Your mold was too hot. You need to slow down. To learn about mold heating, read Veral Smith's book, Jacketed Performance With Cast Bullets! Veral says to dip the corner until you see smoke, then count for...how many seconds? I did for 20 and it worked great.
