You don't list your location, so be sure and check the local laws and what can and can not be used. If as mentioned your in PA and they need a flintlock, then I would go on the auction sites and get a good used flintlock and hunt my heart out.

Some cheap rifles (and I dislike that discription) are the Wolf, Buckhorn, and look for deals on rifles at some of the stores. Someone said they were selling an Optima at Cabela's reasonable.
