I'm very much entrenched in the use of the 16 ga. I have a Rem 1900 12 ga my father gave me years ago and a Rem model 11 12 ga that was given to me, which I use for trap now and again.
A good friend of mine uses an old 870 20 ga he bought new in the early 70's, for everything. He, generally being a better shot than I, couldn't keep from commenting on how I was kicking his butt(and it was killing him), shooting geese at Izembek Lagoon using a 12 ga. Of course, I'm sure the 20 ga steel loads are much better now, than what they were 20 years ago.
