That was a great reply, AL45--
I know some folks hate Chuck Hawks, but this article from his web page is a good quick read on hunting rifle accuracy. "3 MOA is good enough for 100% kills out to at least 200 yards." He goes on to say that a rifle that shoots sub 1 inch groups isn't a bit deadlier than a gun that shoots three inch groups at 100 yards.
