35 yards
I would say 35 would be the farthest I shot a bird.
What is an ethical shot distance?
Depends on the gun,shot, shooter and bird.
If bird is nervous or moving You should limit the range of shots.
If the gun patterns poorly, shots should be limited.
If shot is too small for a clean kill shot should be limited.
If you have not patterned your gun with that shell at that distance you should not make the shot.
If the bird ain't floppin' then you missed or it was too far.
