A bud (non-muzzleloading) got all spun up and bought the 00 mold to make shot for his beloved slingshot. He's stubborn or determined, take your pick. He reports that he's finally getting complete mold fills, but running his lead temp real high and thoroughly heating the mold. He said for the first half of a lead pot he gets about 50% fill rate until the mold gets good and hot, then everything is fine. His solution now is searching for a bigger melting pot. Man, does he ever go through a bunch of balls with that slingshot!
