Wait a minute. You are all riding the previous owner of this gun too hard. No, it is not something I would do to a Cap and Ball gun but I've seen a lot worse. If some one wants to wring the utmost accuracy possible out of one, this is the way to do it. Not everyone shoots cowboy or rendevous matches.
You could flip that cylinder out, insert a conversion cylinder and load it up with 300 gr JHPs and W296 and have one hell of a hog gun.
Giving some one grief over a jeweled hammer?
Did someone just have a severe attack of the troll fever?
$540? I think it was a steal.
