From an old Colt Industries pamphlet:
"FFG black powder is best for large and medium-size revolvers, and FFFG for the small pocket models, but any grade that is available will work reasonably well."
Today I went to the range with my Ruger Old Army. I didn't have any Goex left, so I tried Pryodex FFG. I was impressed by the way it performed in the revolver..
This was at 100 yards - not record setting but not bad for me.
