Alliant/Hercules will give load data for their powders in applications that don't make sense.
I have a 4 lb can of Blue Dot. Wanted to use it. Looked up and by gum Hercules had reloading data for the 9 MM, 38 Spl, 357, 44 Spl, 45 LC, 44 Magnum, 45 ACP.
So I loaded a bunch. Well, Blue Dot is horrible in 38 Spl, 44 Spl, 45 LC. Extreme spreads in the 200-300 fps range, lots of unburnt powder fouling my extractor stars.
The powder was marginal in 9mm, too hot in 45 ACP. Shot well with jacketed in 357 and 44 Mag.
The moral of the story is that just because Alliant puts out data, does not mean it will work well. And this is true of 2400 in non magnum loads. 2400 is a superb magnum powder.
I recommend Unique or Bullseye in the 38 Special. My favorite load is 158 LRN 3.5 grains Bullseye, any case and any primer. I have shot cases of that.
I think Bullseye, Unique and 2400 will more than adequately serve the entire spectrum of pistol rounds. So, you have one third of the powder types, and the one best for magnum cases. Time to get some Unique or Bullseye.
