You can make a .357 rock with WW296. But I like 6 grains of AA#5 for bullets around 158 grains in the .357. It pops pretty good without putting too much stress on the revolver. I used to use Unique for loads in that range, but AA#5 meters a lot better.
In fact, I shoot loads at about the same level in my .357's and my .38 SPL K frames. They're all about the same to me, although I keep my trusty old Ruger Service Six loaded up with full tilt Hornady factory .357 loads for repelling boarders. But for just casual recreational shooting I do up my .38's and .357's at about 950 fps with 158's with AA#5.
