Used in it a .380 and liked it as well as WW231. Burns very clean, better than Unique in this regards. I have switched away from Unique in everything except .38 special. WW296 is a much better powder for the .357/.44 mag and its available, I restocked recently.
Since CFE pistol is becoming more readily available I am going to try it for grins since I load all of the above too. It might make a nice reduced load in the .357 with the lighter jacketed bullets.
