I might quibble with the ‘Hollowell‘s definition in this respect… I believe that chokes can vary in matched pairs. There could be many scenarios where you might want to have a more open choked gun, followed by a more tightly choked gun, particularly with driven game. Then there is the concept of the grouse choke which entails a more tightly choked front trigger followed by a more openly choked back trigger so as to be better be able to take a grouse early as they approach with the first barrel and still have an opportunity for a second, closer bird. The second gun is then choked more openly on the front trigger and tighter on the back trigger so as to be able to take a going away bird behind the butt. Of course with double triggers, the Shooter could simply choose the rear trigger first, But I still believe that choking the pair differently does not I mean they no longer meet the definition.
