Well, tonight I did a half-azzed hardness test on 4 samples from my stash, all ingots and all over a month old. I used an automatic punch on the following, and came up with the following measurements with my digital calipers, measuring dimples edge to edge:
Clip on WW- .072"
SO WW's- .106"
Lino- .063"
Range Lead- .082"
Anybody use an auto punch or anyone venture to take a stab at the hardness of each based on the above numbers? I know this isn't the right way to measure hardness, but I don't have a hardness tester yet and I'm curious.
One thing I found interesting is how hard the range lead was. I figured it would measure closer to pure, and I was surprised to find the lino and clip on WW's so close in hardness...
