Different bore sizes. .733 for Beretta and .723 for Benelli. DO NOT use SBE II chokes in a Beretta it may cause damage to the gun or shooter but, you can use Beretta Optima Plus chokes in the SBE II. This didn't come from Benelli but from George Trulock of Trulock Chokes. When I first got my new SBE II I called Benelli and asked the same question. The guy and the other end of the phone seemed like he had no clue that the chokes were different in the new SBE II.
If you want answers to your choke questions Trulock is the guy to ask. Great chokes and Great Service. www.trulockchokes.com
