On my combination gun Its scoped with 6x42 Zeiss in claw mounts. I have shot plenty of running big game with the scope attached - both moving target and the real thing, and have also shot a few flyiing things with scope still on. It fits me well, i watch the target abd bring the gun up and swing through. I don’t think about the scope - I just look through it and swing.

But if I am specifically wing shooting, scope is off and I just load the shot barrel. It does have open sights if the need arises.
