Just like to remind everyone that the original question (and the one I am especially interested in) was pertaining to a 3" barrel. A lot of you are referring to "snub-nosed" revolvers. Personally, I don't know if a 3" is considered a snubbie or not. To me, it is a mid-sized revolver, with a 1 7/8" being a snub and a 4" being full-sized.
Since I have a 3" .357 as well, I am curious what is best to run. I suspect the 158gr FBI load is probably just fine, but I don't know if 3" is "too short".
