Ok, What am I doing wrong here? I am mixing .25lb. pewter and 10lb. of lead and according to the alloy calculator I "should" be getting around 11.5 hardness. I am actually getting something so low it is not on the scale. I am getting a .0850 on the Lee hardness tester. On the printed chart .079 is BHN 8.
The original mix I did the pewter I used was in raw form and marked with the scans of the composition and it was pretty close to what is in the chart. The second mix I did was using some pewter ingots I bought from a member here. Long time member I am sure I can trust to have good stuff. Both mixes came out exactly the same. I could understand if it was just one or two numbers off but what I am seeing is pure lead.
I am shooting this out of a 45 acp so I am going to use it but I want to know where I am screwing up for future use. I have plenty of linotype and wheel weights but both are short on tin. In case you are going to ask I tested many samples on the nose, base and filed sides.
