Welcome aboard, fifthwheel. As a blackpowder man, you will love your new gun.
Whether by luck, or skill, you have started out with the all time cap and ball classic, the Colt Navy. I need one of them myself.
Go to the above thread, 1858 Pietta 44 caliber for the info you need. Ignore the arguments about the middle east. It is unusual for this forum to get into the realm of politics.
What I find most interesting about the info available from this thread above, is interviews with Civil War combat veterans. These men used your pistol in cavalry battles. You might be surprised about how effective a man killer these old pistols are.
