In my M60-7 I use the Buffalo Bore (#20A) 158 grain SWCLHP-GC +P. It consistently chronograph's at 1025 (average) from the 2" J Frame. Yea - a bit stout but nothing terrible if practiced with.

Out of older J's and Airweights the Speer 135 grain +P short barrel loading is excellent and has less recoil. It will do about 850 - 860 out of a 2" bbl.

The Buffalo Bore standard velocity 158 grain SWCLHP will also do about 850 fps and is not a +P round - although it will usually out perform the old Remington, Winchester & Federal 158 grain +P "FBI Load". Today's version of the FBI loading as made by the "Big 3" has been watered down quite a bit - and YES I do my own Chronographing.
