I shoot higher scores with my O/U than I do with my SxS guns, However they are quite different guns in every way.

I suspect, can't prove, two nearly identical Perazzi's one O/U other SxS stocked the same, choked the same, trigger configuration same, scores would be identical. Might say the single sighting plane is better for one kind of shot but the wider flatter plane may well be better for others who knows ? I don't know what the front of my barrels look like so can't say.
