If possible, I'd like to use just one powder for all three calibers. I want to be able to hit IPSC major power in 357SIG and .40S&W, but 9mm can stay mellow. I'll have a little advantage using my 5.32" barrels in my G35.

Powders I'm considering:

AA9 (might be OK with heavy .40 bullets)
Blue Dot (strong possibility; easy to find)
Power Pistol (strong possibility)
Vihtavouri N350 (might be a possibility)
Vectan SP2 (although haven't seen 357 loads?)
AA7 (seems to be good moderate load for all 3)
Hodgdon HS6 (might be a possibility)
Hodgdon Universal (weak in 357 SIG, but maybe)
Winchester WSF (might be OK)
Titegroup (too mild I believe)
Unique (too dirty)

I suppose the limiting gauge is that there are not very many powders that push the 357 Sig to major power level, but many that can do a nice mellow 1250 fps. Possibly my 5.32" barrel can squeeze 'em up to around 1298 fps?

Any experimenters out there? Your opinions and experience with any of these powders is welcome.

My experiments are on hold because my new KKM barrel doesn't fit correctly. Darn! Maybe I'll be able to start experimenting within a couple weeks or so when it's sorted out.
