I'm enjoying this discussion immensely because I have always liked 16's. They are generally nicely balanced, light weight and can be used for a wide variety of game.
Now, regarding Mr. Mobirdhunters's collection I would like make one observation. If I'm reading this thread correctly, yesterday he stated "John, stay away from 16s.". This morning he provided us a list of his 16b collection, which included 20, that's right, 20 shotguns. And he stated "I like 'em".
Hmmmmm! Kinda makes you think........
As he hinted, he's a hoarder.
