I like Unique for most all my general purpose loads. A lot of guys complain about it being dirty, but in my opinion, that's just BS. ANY cast bullet load will be more dirty than a jacketed load due to the bullet lube, and the very nature of lead. I know that you can cast your own and size them for best performance, but a lot of guys don't cast. I have used a ton of Unique, and I always seem to go back to it. It is just so versatile, that it's hard to use other powder.

Other good powders are 2400, HS-6, 231 (same exact powder as HP-38) for general use in all three of those rounds.
