I have read of reference to a +P .38 Spl 158 gr. LSWCHP loaded with 5.4 grs. of 231 being listed in an old Lyman manual. Generally nowadays the max charge of 231 with this bullet is 5.0, anyone ever use 5.4 grs. of 231?
w231 will NOT give you top fps with the heavy 158 lead bullet but............
it will give you high pressures.
It will work for a SD load if that is all you have.
I don't know about the loading data, but I do know that those bullets need to be pushed at least 1000 FPS for reliable expansion. While the bullets look great, ballistic testing shows they just don't expand unless pushed pretty hard.
