BY "inherent" I assume you are refering to the argument offered for the so called single sighting plane as opposed to the (erroneous) double sighting plane of the side by side. Both actually have a single sighting plane, but it is argued that a SxS may require more precise fitting, to the shooter, for the rear sight (eye) to match properly with the front bead. I suggest this would be a factor more applicable to guns with concave ribs or swamped ribs rather than with raised solid or vented ribs. The former found more on light game guns. Some argue that the barrel convergance of SxS guns creats an angle that makes determining lead on crossing shots more complicated? I think that is more due to the SXS having more to look at when your supposed to be looking at the target. You often hear people say that their problem with the SxS is that the two barrels confuse them. Their just not use to looking straight down the middle where the SxS's single sighting plane is located. Also with SxSs or O/Us the point of impact of two barrels is a more complicated build than for a single barreled gun. Finally, a single barrel gun that does not fit properly can shoot off as well. A shooter, on a trap range, can shoulder his gun and purposefully align his front and mid beads, position his eye to the center of the rib and call for the bird. Many do this. It just isn't what the very good shooters do. This is just all theory, in my case, if I be honest.
