I didn't think that, in an ideal world, patterns should converge or cross over? The idea of barrels converging (in a sxs, not o/u) is that the recoil, because it is not directed in a straight line back to the butt, pushes the shot from the left barrel to the left, and right to the right, so that the convergence is to correct that - just like in a DR? I thought it shouldn't matter at what distance the gun is to be shot - the pattern should still be on PoA for a properly regulated gun?
