Dean Thomas's book, " Roundball to Rimfire, Volume 2" pages 226 to 246, lists two powder charges; 50.48 grains and 52.25 grains. I shoot an original Smith using the black plastic cases and 28 grains of GOEX 3F and a 400 grain Moose bullet sized to .518". This combination produces great results. Everyone shooting a Smith has their own favorite loads, so I guess the most prudent answer is to experiment until you find a combination that works for you.
