     Yes. If you are shooting for points you want the center of the target. If
    you are accurizing the system (rifle, ammunition, and shooter practice) you
    want the smallest group and it doesn't matter where it is, you will adjust
    the aim point.
    
    <> For clustering. A good sniper will still place it dead
    center. Some marksmen can't hit that close to dead center, but still can
    place a consistantly tight group. (And a marksman with a lousy weapon may
    still place shots in a large group.)
    
    This all for iron sights, no optics, no magnification. There are
    thousand-yard competitions for iron sights, too, but they use a much larger
    target.
