I have had several beretta shotguns that shot great with factory chokes but once I put the super tight turkey chokes in and run high powered shells, mainly 3.5 inch shells/hevi shot, then the POI/POA problems begin. Don't know if its the over choking/ pressure, barrel harmonics, or the type of shot wads. Quality of the choke could have something to do with it. I've seen less problems with this using Pure Gold chokes.
