That explains alot. I had some stick on weights in the mix and I used the side cutters on them and they started to melt but did not melt compleetly, I was getting concerned it was zink when they didnt melt as quikly as every thing else. I ended up removing them partly melted. Right now I have been just melting down the weights into ingots. Ive been using wax to flux for now. Im going to order a melting pot, thermometer, flux, dipper, molds for 38sp, 40 S$W, and 45ACP along with bullet sizer dies some time with in the next week. Waiting for a friend to come up with his half.
