For loading cast bullets with Trail Boss how much would you factor in BHN when selecting a bullet?
I have some cast loads that are 18 BHN, but if I'm doing the math correctly for a .38 sp load using 158gr over trail boss, I'd be somewhere around 11,400-13,700 PSI. Needing only about 12 BHN. The 18 BHN seem to fit and fire well (although I haven't tested them extensively).
Is it worth buying a softer cast bullet? Will I see much difference in shooting or cleaning?
(Note: I saw an old post from 2012 that covered something similar, but the post focused more on fit of bullet. I want to know if I will see better accuracy and less leading in 12 BHN vs 18 BHN? Is it worth another purchase? I can easily use the 18 in my 357 loads, and would like to save them for that if I'll get better loads with 12 for the .38. Otherwise, I'll use 18 in both.)
