All factory chokes are not created equal. Even though I like Winchester and Browning shotguns I feel their factory chokes are sub-par. Benelli/Beretta factory chokes are better. I prefer extended chokes because I can tell at a glance which choke I'm using and they protect the crown of the barrel. Many people think extended chokes pattern better than flush. From what I have read and backed up by the patterning I've done, that is not the case. The exception is sometimes extended chokes pattern better when shooting heavy loads of steel shot.
