NO, absolutely NOT!!! You will destroy the rifling in the barrel. You can only ONLY use a smoothbore barrel. Many places sell Encore muzzleloading shotgun barrels if you do an on-line search. My best suggestion would be to find one and use it.... you're not going to find a shotgun that feels better in the hand that the Encore anyway. I had to laugh when I see some of these guys suggesting other guns..... they have NO idea just how impressive the Encores are!
