I’m comparing 3 alloys, all of which (by Bumpo’s Calculator) are at an estimated hardness of 13.0.
Alloy 1: Antimonial Lead at 5% Sb, 95% Pb
Alloy 2: 1.56% Sn, 4.34% Sb, 0.23% As, 93.9% Pb
Alloy 3: 3.12% Sn, 3.81% Sb, 0.21% As, 92.8% Pb
My question is would a barrel react differently in terms of leading, antimonial wash, etc between these 3 alloys? All are at a hardness of 13.0.
Assuming the load is adequate to the strengths of the alloys; boolits sized correctly etc., could the alloy(s) composition result in differing barrel condition(s) between the different alloys? Or should they all behave the same due to all being of the same hardness?
Another question, what if one was to water drop 25:1, 20:1, 16:1 etc to achieve a hardness of 13.0, (assuming these would harden without antimony / arsenic) would all of these alloys behave the same within the barrel?
Just curious…
