I bought about 50# of lead from a deceased reloader and I do not know what consistence it is. I know HE planned to use it to make bullets, but I do not know if he intended to add something to it. I have a feeling that it is all older wheel weights, but I have never used wheel weights. I have two or three new Black Powder Cartridge shoots that want me to cast cheap bullets for them. If I were to cast bullets for them, so long as the lead consistency was the same, would it work.? I could keep them supplied with the same stuff for quite some time. Would you add anything to the mix?.
