I want to make some 38 spl +P.
My normal 38 load is 3.7 gr of Titegroup with MBC's Cowboy # 11 (158 gr LSWC 12 BHN)
I don't know what the formula is for deciding on the hardness of the lead.
I'm wondering if I can still use the same bullets or I also have .357 Action which has a hardness of 18.
Is BHN 18, too hard?
If I use 4.2 gr, the pressure should be up around 19,000 cup.
