I am looking around for another lead free alternative for casting; I have been using a food grade pewter for quite some time now, but pewter has about half the specific gravity as lead. Because of pewter being less dense than lead, quite a bit of my bait designs tend to run sideways, because they do not have enough counter rotaing mass. I need a a castable allow that is about as dense as lead or at least denser than pewter. I have read about people using bismuth alloys and copper alloys, but I never got enough info on those alloys to switch from pewter. If you have any ideas on other alloys and maybee a supplies that would be great.
