If you are looking for a break open with the possibility of swapping barrels for $400 or so I would recomend a CVA. The Optima Elite is right in that range and that includes a centerfire barrel if you get the combo. I bought mine from D!cks last year black with blued barrel for $399. After I bought it all I did was send in a form and got a center fire barrel to go with it. Just make sure you get the form from D!cks. I think I recently just saw the combo on sale for like $329. I've gotten the best group I've ever shot with any rifle with the muzzleloader barrel. .75" @100yds. I know Basspro has the combo as well and may even have the stainless for a little closer to $400.
