The 28 gauge is for relief of boredom. A 20 ga. with 3/4 Oz. loads neutralizes any need for a 28 ga. Yes, it's a hair smaller across the breech face, and yes, the shells are a wee bit smaller in the pocket. Nothing really worth much. There are some really slim and trim 20 gauge guns that will match a 28 gauge's handling qualities. Otherwise, it's just a boutique gauge with guns to match. It serves no other practical purpose. But since when does practicality matter to anyone who wants a 28 gauge?
