Hello Guys,
Im getting lead build up during the casting session on the edge of the cavity's per the pic shown, the moulds are Magma 180 grain RNFP 45lc and are hand casted with two moulds simultaneously at around 125 cycles a hour each for usually 4 hours, I run the pot at 700 f and are using Wheel weights with 14.3 Brinnel hardness, before use the moulds are scrubbed with mineral spirits and vents lines etc are all clean but still seem to get this build up ? Any ideas to help eliminate would be appreciated
Cheers
