David, I wish I could help with comparative figures, but I can't. I've loaded lots of 3N37 in 9x19, though, and a little in .40 S&W and .38 Super. It is very clean and pretty flash-free, and outrageous velocities can be attained with it in 9x19. It was one of the original powders used to make "9 Major" in IPSC, back when Major PF was 175 and before 9 Major was banned for awhile. You are correct that the price is too high, but it is good stuff.
