Good info! I'm curious about percussion vs flintlock. Was there a significant difference in loading time, or just reliability? Can anyone summarize the steps in loading a percussion weapon? And what about the Colt Revolver such as the one mentioned above, or the Navy Colt of 52? Were these cartridge-firing weapons? I have also seen a quote from a Mexican War veteran which mentioned "double barrel shotguns"...were these breech-loading percussion weapons?
