well, semi automatic is a relatively mild gun. it just means it fires every time you pull the trigger. That's not so bad. One usually carries more than one round in the gun while hunting. Does it really matter if the gun cycles the rounds for you? Also, my brother and I have both hunted deer with handguns, including the Thompson Center Contender and the great XP-100 (http://www.remington.com/library/history/firearm_models/centerfire/xp-100.asp) which was like a space gun. Only with bullets. Also, it was a single shot. It was cool.

The intent might not match your present day interpretation :-D ...
