It depends on what you mean by auto. I use two of my semi auto rifles for hunting. My Ruger 10/22 is a good rabbit, and squirrel gun. I use a modified AR-15 for coyote hunting. These guns are good when you need a quick folow up shot, and most states restrict the capacity of magazines for hunting. Here where I live we are limited to 5 rounds or less when hunting.
The goal should always be to kill with one shot and a patient experienced hunter should need just that, one.What I have never understood is some nimrod in the woods with a single shot.
