I have a question of opinion on barrel convergence. Consider that the barrels are about one inch apart on center at the muzzle. Consider that the only curve in pattern flight path is ballistic drop. IMO, barrels should shoot to the "same" (within one inch) point at all distances. If not, there must be a built in divergence or cross-fire. That is to say, you cvan't have a multiple inch divergence at 20 yards followed by a convergence at 40 yards.

What think ye?
