Tire weights will work well for jigs and anything else if you mix it with a soft lead. Otherwise to many cold spots. I just went to the scrap yard and asked for lead and they took me out back and let me pick it out of a bin. Old machine parts. AWESOME soft lead. @ 30 cents/lb. Use those mini muffin pans from Wal-Mart for about 8 bucks for your ingots. Pour your tire weights into muffin pan, and when your done, label a box "wheel weights" and your soft lead, lol well, "soft lead" If you buy a little lee pot, the one that plugs into the wall, you can mix your lead. 2 tire weight ingots, and 2 soft lead ingots.And the pot is full. I've had some VERY close calls with 612 degree lead so please BE CAREFUL. My accidents (thankfully) didn't hurt me but was due to carelessness. NEVER clean lead with anything!!! Only remove the slag and garbage with a spoon or Needlenose pliers. Just bang off dirt on wheel weights. Any moisture in the lead, something you can't even so will cause it to explode out of the pot and right into your face! But it's really straight forward and you'll have a blast making your own baits. Hope this helps.
