Kavorka:  Keep in mind that most military rifles have sights intended for the battlefield and not 100yd. target ranges.  I have a 1904 Manual, "Firing Regulations for Small Arms", published for the United States Army and Organized Militia.
  The Scoring Forms for Competitions it contains have qualification matches fired at 200, 300, 500, 600, 800, and 1000 yards.  The Bull's-Eye Target was being "returned to" or substituted for  figure targets, which were silhouettes of infantrymen and horsemen.  There was a tendency of soldiers in combat to shoot too high.  U.S. troops were taught to "aim low".
  "141.  Short-Range Aiming. -- The trajectories of the rifle and carbine are so flat that the sights have not been arranged for any elevation less than 300 yards;  within that range the gun will therefore shoot high, and should consequently be aimed below the bull's-eye." (page 82 - Firing Regulations for Small Arms - 1904).
