I've used W231/HP-38 in 45 ACP and 45 Colt.
It's a fine powder for lots of different cartridges, if I had 10 seconds to grab powder off a shelf it's one I'd snag. Better powders for specific things can be found though. For example with 45 Colt it's a little fast and doesn't take up enough space as I'd like. With 45 ACP there are cleaner powders that shoot softer with better chrony numbers.
