With the .357 it is all about penetration. You will NOT be impressed with the knock-down or "power" of this round, but they will eventually bleed out if hit in the right spot.
Personally, I have found the .32-20 (out of a revolver) to be just as effective as the .357 on deer size game....and neither is anything to brag about.
With this in mind, I would choose a hard-cast bullet of at least 165 grains (180 is very good) over any type of jacketed expanding bullet. The .357 just doesn't have enough velocity to be reliable with any expanding bullet and more weight generally means better penetration with any type of solid (hard-cast) bullet design.
