I like my side by side 20 for pheasants in the corn. I like My 12 for ducks and geese. And I like my 16 for everything else. Don' t own a .410, but from what .410 owners say I must be miossing out on some fun.
I sincerely apologize for mentioning the 16 gauge without it being mentioned in the opening post that was edited to include some additional gauges.
