28ga shells are cute, but expensive. Anything a 28 will do, so will a 20--which you can easily load down to the standard 28ga shot charge of 3/4 oz. 28's are nice at short range targets (like skeet) and small, relatively fragile birds. If built on a true 28ga frame (which many are not--you'll often find they weigh more than the same model in 20ga), they have wonderful carrying and handling characteristics. But if you're just shooting them at clay birds, other than using them in small bore competition events, they don't make a lot of sense. How they carry is not an issue, and you're actually better off with a heavier one vs a lighter one--which, in my book, defeats having one in the first place.
