I dont know if you can still do this as my metal recycler burned down two years ago, but I would go there and occasionally they would have sections of lead pipe that your fingernail would mark. My not so scientific test for hardness. Thankfully I gathered up a supply as shooting 370 grain fifty cal maxi balls eats through a pound of lead in nothing flat. When hunting lead bring gloves as there aint no telling what was going through those pipes as in grey "water", Cheers.If you let it sit in the smelting pot long enough the tin and antimony should float to the top and be skimmed off with a spoon. That should give you a better quality lead ( softer).
