You might want to check out and even join The (traditional) Muzzleloading Forum. I noticed a few nice rifles for some good prices over there. There is one CVA Hawken with all the accessories for $250. And there was also A TC with accessories for the same price. There are a pretty good group of guys on that forum also, that will answer any questions you might have. And look at those rifles with the accessories. Heck you can spend as much(or more) on the accessories as you spend on the rifle itself.
I just looked at the classifieds over there. And there are a bunch of nice rifles over there for sale. Tom.
