Part of what happens during cooling/solidification of WW metal is the antimony crystalizes out before the lead solidifies. The (hard) antimony is then held in the lead as a two part matrix, much like rocks in concrete, leaving the exposed soft lead to smear onto a bore more than it should. That does't matter for wheel weights but it does for bullets. A little bit of tin changes the mixture into a real alloy and that makes MUCH better bullets
You sure about that..........
