Just for sake of curiosity did the test on my revolver balls too.
Scrap lead from airgun range is the softest of those.
Lead I bought at during one competition this summer (selected the softest ingots for casting) is in the middle
Wheelweights (or .22 range scrap, not sure which one as I got these from another clubmate) is the hardest.
Punch left clearly different size indentation on each of those balls.
