Well h&r doesn' t sell a muzzleloading/rilfe combo.
They did last year. But you can buy any centerfire H&R/NEF rifle and send it back to the factory and get the muzzleloader barrel for $77. I haven' t shot a Rossi so I can' t speak to its accuracy or reliability. I can say that they look cheap, feel cheap and until I hear otherwise I will remain leary of them.
