I use a punch set to label mine. A " W " for wheel weight, a " SW " for stick on wheel weights, a " R " for range scrap, a " P " for pure roof sheeting lead, and a " S " for range pickup slugs. I have a lee hardness tester, but haven't tested any of the hardness yet. I don't load much rifle bullets and when I do the wheel weights have worked fine.

I commonly create a batch of lead to cast into similar ingots. I measure the hardness of each batch and write that on the ingots with a sharpie pen that way I know if I'm casting rifle bullets to use the harder alloy. And if doing pistol bullets I know to use the softer alloy batches. Having a tub of randomly hard ingots could be confusing in the future
