I don't like to have to empty my hoppers to load a new powder. The FPS I'm getting from my OP is good for me. I may try to bring the SD down under 10 but will take to the range first.
There's no nice way to put this: That's THE dumbest excuse I've ever heard for making a lousy powder choice work in a given cartridge. Do you also use Titegroup for your 223 and 308 loads?
