I agree with MSP Ret, a couple of years ago I bought the 12ga turkey barrel with the NEF turkey choke tube fitted to my .223 receiver. It patterns well with the 3" Winchester Premium #5 turkey loads (better than #4). If it didn't pattern well, I could have tried one of the aftermarket turkey choke tubes. Later I bought a rifled choke tube and have been very pleased with it handling the Remington BuckHammers. I also have a mod. choke tube from an old shotgun that I found at my father-in-laws. Very versatile gun.
