Well according to Chicoine's "Gunsmithing Guns of the old West" on page 23 it shows,
38 special 158 gr Baloon head case Solid head case speed
21 gr FFg 19 gr FFg 850 fps
38 long colt 150 gr 18 gr FFg 16 gr FFg 760 fps
Lyman's black powder only lists 38 special
158 gr bullet
goex ffg 17 gr 561 fps
goex fffg 17.5 gr 642
pyrodex RS 17 gr 638
pyrodex P 18 gr 635
So that's quite a difference in sources, those are the only 2 I have on hand for BP.
