My Cabine Tree tester indicates certified 99.99% Tin BHN at 9.
Cast Bullet Association Alloy Calculator indicates Tin BHN=30 !
Los Angeles Silhouette Club chart shows Tin BHN= 7
Midway sells Tin but indicates BHN=Not Available !
At least one other source I know indicates it is 30 !
Anyone else want to give their measurements ??? Using an alloy calculator is great fun when are you not sure of the actual hardness of the components !
I just looked up Sn in the Handbook of Chemisry and Physics BHN= 2.9 ! Two other sources show BHN=3.9 & 15 !
