I have seen a 10ga that I would not mind carrying after Mr BobWhite, but Nary a Foe10. The 10 was a Barber & Lefever hammer that I believe had 28" bbls & felt as if it weighed about 7Lb.
Since it seems most everyone around here thinks you can't hit anything with a gun lighter than 6lb anyway I see absolutely no reason for anything less than a 20ga.

I just categorize 10ga through 20ga as shotguns, anything bigger is a Big Bore & anything smaller is a PipSqueak.
