There ya go. You'll get pure lead out of the powerbelts and they make excellent round balls and if i had a conical mold, they'd do great for that as well.

If your finger nail easily cuts into the lead you do have, it will work.

Wheel weights are really hard and thats why i only use them as target rounds for my round ball shooters. Probably be great for game too as they are hard and would offer deep penetration.
