So with a choke of no more than Improved cylinder with a 1984 model winchester 23 Heavy Duck could I shoot modern numbered (usually #4) steel shot. I just find it hard to believe that a gun manufactured during a time when steel shot was required in certain areas for waterfowl that winchester made a Heavy Duck gun that would not handle steel shot.
I called winchester and ask them what the standard inside bore diameter was for a 23 HD was and the reply was "we don't have that information". I ask about shooting steel shot in the gun and they said "no". How can you not know the standard internal bore diameter, but know if you can shoot steel.
