I set the moulds on a small (6")/cheap fry pan on gthe hotplate, and cover with a small (4-5") cheap pot for about the time it takes the lead to melt (20-30 minutes). The plate is set to 3.7 on a scale of 6.
I'm casting #2 at about the same temp (700-710-ish) and have gone as high as 780 in the past. That's normal.
DON'T Bang the moulds directly. Get a plastic or rawhide hammer and tap on the top of the handles'
HINGE pin to loosen the bullets. They will loosen/drop in 2-4 taps (smacks if so needed.) NOT the moulds themselves.
