I have been looking into getting a flintlock rifle and smoothbore. Recently my local gunshop got some muzzleloaders from a recent estate sale. The smoothbore that stood out the most was a Thompson Center New Englander. It was a percussion 12 gauge smoothbore. The gunsmith there said for $90 he could switch the breechplug over to flintlock and he could sell me a flintlock for the smoothbore for another $50. The shotgun has a choke tube in it. I never knew muzzleloaders had chole tubes. Which is why I came here to ask before I buy. Is this smoothbore some homemade job or did Thompson Center made these brand new with choke tubes ? Secondly, are the choke tube shotguns terrible muzzleloaders ? Thanks in advance for the help I have been struggling to find anything on a Thompson Center with choke tubes besides a gun called the "Encore".
