From what I know of the alloys and how they co-mingle, I believe what snuffy said was correct. Tin would MAYBE give 1-2 bhn hardness on its own once you get up to 1-2ish%, unless just by tin being harder than lead, it jumps the hardness a couple points right away. if that makes any sense. I think the 30-1 is testing about right, but mayber it could go up 1. I don't think that projection line is going to be straight. The radius of the ball has to be taken into account. The part that pushes into the ingot or bullet would have to be a sharp cone for the line to follow inline. My guess anyway
