I've seen various ways to measure lead hardness, and for most things that I shoot (pistols) cast lead in, it's not a big deal. Everything from straight COWW alloy to 50-50 COWW/pure and 2% Sn. However I'm casting for .35 Remington and .44 magnum in long guns and would like a bit more insight into the alloy. Currently I am using the 'lead pencil method' of measure relative hardness. I am looking into a cabintree type hardness tester but just wondering if it's worth the scratch, as the pencils give me a ballpark idea. I also scrounge lead from various sources and would like a quick way to test what I am getting.
