I believe it is Whitacre (sp?) that makes various model rifled musket barrels for competition. Go to the NSSA site and there should be a link to them.
If a pair of '51 Navies were good enough for Billy Hickok, then a single Navy on my right hip is good enough for me . . . besides . . . I'm probably only half as good as he was anyways. Hiram's Rangers Badge #63
