In the movie "Behind Enemy Lines" when Gene Hackman seeing the first shot miss target, told the sniper to make an adjustment to his Garand(?) of 3 mils then the sniper was shown moving the sight knob 3 clicks (all as best I can remember). Garand knobs were almost 1 MOA, not mils which were about 3 MOA. Details, Details..... Forget 'em and enjoy the story.
