1lb bees wax
6oz bol-wax (thats a #1 bol-wax ring from the hardware store)
6oz crisco (one of those crisco "sticks")
6oz canola oil
Melt it all down at 375 for 30 min in a big frying pan in the oven, then, pour into pans with bullets layed out in propper fasion.
(8x8 pans work quite well for 50 bullets staggered)
Pyrodex Select and Pyrodex P work just fine with it.
777 doesn't need it, but, I think it helps
GOEX loves this stuff
