Talking about clickety-clack 28 and 16 gauges overall lengths compared with break actions. On scaled to gauge receivers, the bolt doesn't have to travel as far on shorter length chambers to clear the ejection port. 12 and 20 gauge shells can be 3.5" for 12 gauge and 20 has 3" maximum hull length hence receiver needs to be longer than 16 or 28 gauges. However as I noted Fiocchi has announced 3" shells for 28 gauge. Not sure which gunmaker will accommodate the 3" shells.
PS: Benelli has announced a 3" 28 gauge
Not trying to be argumentative here with this GLS, but none of what you mention about bolt travel or even scaled-to-gauge receivers affects OAL worth mentioning. Even a 28 ga. A400 receiver, which is scaled to a 28 gauge shell, has enough difference in length to a 12 ga. version to amount to anything discernable in handling or dynamics.
From whom does Benelli think the 3" 28 ga. shells will be derived? Makes about as much sense as introducing a 3 1/4" 20 ga.
