There's a reason why people who really know small revolvers often keep them loaded with wadcutters. To really get what is possible from a 158 grain .357 magnum load you need at least a 4" barrel. And even then, it's going to be pretty damn zippy even out of an N frame with a longer barrel.
In a snub you're mainly getting extra flash and hellacious, downright painful recoil. A combination of revolver and ammo that absolutely punishes you with every press of the trigger will help guarantee that the compromised performance you get from that .357 load is much less likely to be delivered to a spot on the dude who wants to hurt you that will count.
It's going to take multiple shots with a handgun of any sort to make someone stop their actions, so if you're using a snub you want to prioritize the ability to make multiple accurate shots in a hurry. That almost always contra-indicates .357 magnum loads in small revolvers.
I keep my model 12 loaded with match wadcutters. They shoot a tad low, but accurately...and crucially I can make multiple shots to a pretty small target at speed because the recoil isn't a problem.
