If you want clean, look at Vihtavuori powders. N320 or N340 would probably work well for what you're looking for.
Power Pistol is better with fairly warm loads. Tends to burn less clean with midrange loads (at least in 45ACP, 44Mag and 357Mag loads I've tried).

I use Power Pistol to replicate Speer's short barrel 135gr .357 Magnum ammo.
If you're looking for a substitute for Unique that burns cleaner try Universal. Universal was created as a alternative to Unique from what I've read. I use HS-6 and sometimes Longshot for mid-range .357 Magnum ammo.

Personnalky I would choose a faster burning powder for mid-range loads. For light loads with jacketed bulets I prefer American Select while with light lead bullet loads I enjoy using Trail Boss.

I use the max Alliant-listed Power Pistol .357 loading (8.0 grains - this is what they list for jacketed bullets, but cast bullets give lower pressures with jacketed loads) and a CCI magnum small primer under a 158-grain .357 LSWC from Tennessee Valley Bullets with a solid roll crimp. It's a decently accurate, moderate and clean .357 loading, and real pleasant out of my 3" K-frame: sort of giving .38/44 performance, a good easy-shooting .357 loading.
Out of the 3" 65-5, 36°F @ 5950'>sea level:
M 1147 fps/ES 28.46/SD 11.61.
Out of a 4" GP-100, 80°F, same range:
M 1226/ES 9.71/SD 4.35 fps
It's sort of one of those loadings that I try to always keep around. Just a good basic load.

My starting point would be closer to 9.5 for 125 gn jhp.
