Canvasback,
I realized after you mentioned favorite guns, that is what draws me to the special ones and not their gauges. I've never owned a 16, perhaps because people steered me away from them when I was starting out long ago because of ammo and the like. I've read numerous times about it's suitablility as an upland gauge, and it's barrels being the perfect diameter to fit in one's hand, overall weight, shot load, etc. Now that RST has me covered for shells for any bird that I might persue, I really owe it to myself to have at least one.
