All of these topics surely are centred around the fact that the OP and I and others are concerned about missing?
For instance , shoot at a simultaneous pair , first target smashed , central, no problem, second target is now 40 yards away edge on , we shoot at it and miss, (regularly!)
So now the doubt creeps in , is second barrel shooting to point of aim ? does my gun fit me ? did I lift my head? and a multitude of questions all without answers , unless we slow down and think. Many , many of us will unthinkingly shoot at a very distant target with a very open choke which by the time the pattern reaches that target is very open , you may well be central on it but be unlucky enough to have the edge on clay slip away.Lasers and Pattern plates will only identify static aimed shots , and we all know , you don't aim a shotgun , you point it at what you wish to hit.
Shoot it often , both barrels at a straight going away target , build confidence in shooting your gun at what you are pointing at , use enough choke and a suitable cartridge that you know works.
