turkey gun with a screw in choke was born. He later sold the patent to Winchester and the Win Choke was born. I still have that bbl and hunt with it.
In my opinion, the winchester 1300 turkey barrel is one of the finest that's ever been made. Some of the tightest longer range patterns I've seen out of any gun.
