Yeah, 16s can be a little cheaper to reload than buy factory. But there's still plenty of relative affordable (and effective) 16-gauge ammo out there. An ounce of shot patterns (and kills) great in a 16, and there's plenty of that out there, for less than exorbitant prices, especially if you buy a case.
The big reason drillings are most commonly in 16 is weight. It's kind of amazing how much less they weigh than 12-gauge drillings. Have owned and hunted with several of both.
