One comment re cleaning per Steve's recomendation. According to an article I read many years ago in the "Rifleman" this method of cleaning was generally understood in the days these guns were being routinly used with black powder. This water cleaning also dissolved the corrosive salts which was a component of the primers of the day. Much of the piting found in guns of this era today, which is generally blamed on the BP, actually came about after the owners switched to smokeless & not realizing the dangers of the primers used was not so prone to cleaning his guns. Today this is still a cheap, efficient method of cleaning a smooth bore breech loader & primers are generally not a concern anymore.
