Apparently my original info was wrong, you can use either for pistol, you just have to use the corresponding data for each (old data for old powder, new formula data for new powder), there are loads for 9, 38, 40, 45.
Ok, I'll take the 8 lb seals keg. when and where do you want to meet? I bought a bunch of misc. powder awhile in the F&S parking lot from a guy in a Jeep was that you?
