https://www.ballmoulds.com/ Any of you used this companies molds ? I'm thinking of ordering one mold for a single ball inside the SP-8 wad and then two molds of about 420" to make 000000 buck . 4-0 is .380" 5-0 is .400" and 6-0 should be about .420" . Winchester Industrial loads an 8 gauge round that has eight .425" zinc balls , I don't wanna load to their pressure level of course and I won't use zinc but by my estimations eight .420" balls should be about 2 ounces so its doable just not to fast and pressure oughtta stay within reason . The single roundball load should be doable as well but I'm sure this one will exceed 2 ounces so again doable but restraint is a consideration while loading .
