As a 2400 replacement, i also second Accurate 9, i used it as Shootersworld "Heavy Pistol" (Lovex D037.2). It gave good speed consistency from 12 grains upward, i went up to 12.7 grains which gave about 1300 fps with the lead SWC (19%Linotype). It was shot out of a 6 inch Colt Python.
Accurate 7 works well, too (D037.1), it is a bit higher on the pressure, it somehow had a velocity spread, but it works well.
What i now settled on for competition use are 8 grains of Ramshot True Blue. This gives less of a magnum thump, but a dead on accuracy. Also Shootersworld Auto Pisto (D036) did a great job at like 8 to 8.4 grains.
All of the above powders meter like water, particularly True Blue.
What gave me no luck at all was Enforcer. I even had a squib load for ignition failure with a .158 FMJ, i had to poke it out with quite some chiseling. So, it is difficult to ignite and even more difficult to bring to a consistent burn, maybe only at max charges. I now rinse it in .44 Magnum, gladly i got me a 29 to burn it up, it was just sitting around. Not a good powder fo .357 in my gun at least. Even for the .44 at 21 grain, the velocity spread was like 60 fps with 227 grain bullets. It thumps well, but thats about it. I will try it with plated bullets next in .44, still upping the charge.
But for your intentions, Heavy Pistol #9 might be closest. The powder crummies are also perfectly spherical, it is a blast to work with, very pleasant. Happy loading!
