Joe;
One set of sights & one bbl can be sighted to point of aim at any desired distance. As far as horizontal displacement it will go from the distance bbl is off set from sight line at muzzle to Zero at sight-in distance, no further. It will of course cross at that point & continue to gain in opposite direction as range increases. The problem with an offset scope on a 94 is more a matter of having to get ones eye behind the offset scope than any inherant eror in the sighting itself. In this case the sight line is centered to the gun, the bbl is offset, much easier to work with.
