Buffalo Bore 158gr LSWHP .38 load gets 1000 fps from a 2 inch (I chronoed that myself from a 2 inch 64 and 1100 fps from a 2 3/4 inch Speed Six, again I chronoed that myself.) I use these in my Speed Six to!
Cor-Bon DPX .38s and .357s seem to work very very well from any barrel length to. I keep a snub airweight with the DPX .38s now as the BB load above is just to much for a 15 ounce gun!
