I recently picked up some Wolf Gold 357 Magnum, 158gr. SJHP ammo and thought I'd share the results of shooting it through my 19-7 PC revolver. I'd like to start by saying that Wolf doesn't load this ammo is actually a private labeled for them by Prvi Partizan ammunition company.

If you follow the link you'll see that their ammo was tested out of a 10" barrel at 490 meters/second which is roughly 1600 fps.
Out of my gun, on average, the load clocked 1160 fps out of a 2 1/2" barrel. Given that the chrono was at least 15ft. away the average was probably very close to 1200 fps.

I didn't have any trouble keeping a cylinder full inside 3" at 25 yards offhand. That's not saying anything about my ability but the accuracy of the gun and ammo.
