Doing some research on the best powders to buy to build up a few loads from .38 Special (standard pressure) to .357 Mag rifle loads.
The.38 Special (standard pressure) will be fired in a S&W Mod 12 (alloy frame) and a non +P S&W Mod 14. I'll probably use both 148 gr LWC and 158 gr LSWC for these guns.
A light .357 magnum target load for my 6" S&W Mod 19. 158 gr LSWC @<1000 FPS.
For my 4" Mod 27 and 6" Mod 28 I'd like something in a 158 gr JHP @ ~1250 FPS.
Last would be a load specifically tailored for a Marlin 1894C (micro-groove rifling).
As I understand, Unique & Win 231 are good general purpose powders for the .38 Spl and should also work for the .357 light target load. 2400 seems to be a good powder for the .357 Magnum and should work well in a rifle load. Are there pros/cons to these powders over others?
