Get a Lee 20 lb pot with bottom pour. It's a lot faster than trying to dip and pour. Get the 6 cavity mold. You'll be glad you did. I have a Hensley & Gibbs 10 cavity 38 cal WC mold. 10 bullets at one time really adds up in a few minutes. Unless you have some tin or Linotype then you don't need the flux. I use pine sawdust for flux when I'm making hard casts. When you melt the wheel weights you'll probably find a few Babbitt weights. They won't melt and will float on top. Just throw those away.
