I know this post is kind of old but here goes....From how far away are you patterning? If it is 6'' high at 25 yds that may be of some concern. If it is at 35 or 40yds it shouldn't matter at all. You have to be an excellent shot to notice 6" at much range. From my experience shooting the shotguns I have owned, many have shot off of center, still managed to hit birds with them though.
