So it seems that BP rifles and BP cartridges for rifles typically use 2Fg granulation whereas revolvers used 3Fg. While a Walker is a revolver it can hold a charge (60 grains) approaching that of a rifle cartridge (.45-70) load. I was just curious as to what the net affect of using 2Fg in a Walker instead of 3Fg. Is the issue that the 2Fg is slower burning and thus not a good choice for the relatively short barrel of the Walker? If you put a 20 inch barrel on a Walker then the granulation of choice would then change from 3Fg to 2Fg? Additionally, if you shoot a heavy conical out of the Walker instead of the much lighter .454 round ball would it make sense to shoot with 2Fg?
It would appear that for some, who have a conversion cylinder for their revolvers, the preference is to use 2Fg for their 45 Colt loads. Is this because they are using a 255 grain bullet instead of a 135 grain round ball?
