Why are Beretta Optima choke tubes so thick?
As noted above under the Optima-Choke Plus section, the extended use of high performance steel and metal alloy non-toxic shot imparts considerable stresses. In the case of the Optima-Choke Plus part of the solution was to use a choke tube design offering a thicker choke tube wall to better resist these forces.
What kind of choke system does a 680 series Shotgun use?
