For the past 2 weeks I have been remelting lead I purchased a few years ago into 1# ingots. Range, soft, COWW, SOWW, stained glass, and unknown lead melted in separate batches. I checked hardness today of 2 ingots from each batch. My Lee hardness tester chart stops at .079 indent (8.0 BHN) but I had several indents measure .082-.100. Does anyone have a chart that gives hardness for indents over .080? 60# pressure using 5/32" ball.
Thanks in advance.

I have one in PDF format. I'll see if I can send it as an attachment in a PM.

I saved the picture, but can't read it. Too low resolution maybe

Here's an online calculator. The units can be changed to what units you want. Hint use .15625" for 5/32".
