Well if one is ground shooting birds at stone's-throw distances, yes, they'll destroy the bird (I'm not suggesting you do that grayrc). That's why you don't shoot them that close with a shotgun. Even better if you shoot them after they flush because then you generally nail them in the back. Choke was designed by waterfowlers; for us upland game hunters it's a nasty handicap. Open cylinder or IC and LIGHT loads (1 to 1-1/8 oz) from a 12 will make a deadly wingshooter's gun. Smaller gauges are recommended. It doesn't take a lot to bring down a ruffie on the wing.
