you would THINK a bullet mold maker could do this. I had 6 places turn down $200 because they said they could not do it. After that i said fudge them, i'll do it myself. Once i get more aluminum and a bench press drill i will be all set. I feel the results will be a lot better once i get the lead temp. in the 700* range and then pour into the mold. I also read that ZINC is hard. Im not sure if my simple campfire will melt zinc though.
