You are not the first person to realize just how powerful the smaller shotgun shells can be. Not that the 410 should be used on such birds, but I started pheasant hunting with a 20 gage when I was stationed in North Dakota. After 2 seasons, and a lot of hunting, I only ever lost one bird that I hit. My hunting buddies all hunted with 12 gages and several soon started hunting with the 20 as well. Also, there has been a small resurgance of the 28 gage as well. A perfert tool for Quail and such.
