Another option is to get a drop in Green Mountain barrel. I bought one for my TC in .40, but you can get one from .32 all the way up to shotgun. The barrels are real drop in, i.e. they have the sights, lock (flint/percussion) nipple, and ramrod included for about $150. Here is a link for the drop ins for the TC but they have them for others also, just go to the home page and click on muzzleloader parts.
