I just started fooling around with a .44 cal Steel frame 1851 Navy revolver. Two different books came with it. One looks to have been printed by Pietta Brothers in Italy. The other looks to have been printed by Traditions. Page 10 of the Pietta book says that the proper powder charge for this revolver is 12-15 grains of FFFG. Page 4 of the Traditions pamphlet says that the proper charge is 22-30 grains of 3F with a round ball & 19-25 grains of 3F with a conical. Ain't that just a kicker? They give you two grossly conflicting specifications on the single most important piece of information that you need to use that darn thing. I'm going to have to write a few letters to somebody about this one.
