Not a factory .357 load... not "science"... but I fired a few various hand loads from 13.0 up to 14.5 grains 2400/158gr XTP, into cat litter jugs full of water @ 15 yards or so, and all of them expanded fairly well when fired from my 60-10. Penetration was what I would consider deep, for a pistol JHP bullet. 13.5gr isn't bad... 14.5 grains was for sure into "sporty" territory, but still extracted just fine, with zero sticking. I have not chrono'd these loads, but I imagine the top end is well into the "full house" realm.
I imagine the factory stuff would be fine. The 2400 loads do have a flash to them!
