Yes, an amusing topic that comes up not quite as often as "what choke, load, mayo or mustard for late season pheasants?"
A light twelve is still .729: it can never be .662. For me, weight is a minor consideration with a 16. A scaled frame round action 16 in my large hands is a delight to carry, and if your boots are not in a blind or standing on concrete calling for a "bird," but putting in the miles over the hills and plains and in the woods, the 16 is neither obsolete nor rare.
It is, as stated previously, my Goldilocks gauge.
