A couple of months ago I posted a discussion about the hardness of the Military surplus wheel weights that I had purchased. I made the statement that they seemed to be much harder than the old wheel weights. When I melted the WW's they seemed to contain a lot of Tin. I posted a discussion about testing the BHN with drawing pencils and the experiment seemed to be right on.The BHN of the Military wheel weights was 21. With this way of testing the hardness I tested old ww's and the BHN was13. I'm going to buy some more of these Military surplus wheel weights. I think this alloy is what I've been looking for for the .17 caliber experiment.
