RHelm:  (Hint) - If your Krag shoots high at 50 & 100 yards, simply staple one bulls eye above another and aim at the lower target.  At this point, you want to shoot for group size and not be overly concerned with shots going to point of aim.  If you start correcting and use 'Kentucky windage' to try and get 10s, you will be all over the place and will not know your rifle's potential.  Use a consistent sight picture and shoot groups.  Elevation can be changed later by using an altered front sight blade.  Remember, the 1896 sight's lowest setting is just under 275 yards.  In this position, it was intended to be able to aim at a 'standing' enemy's belt buckle and score hits (head to toe) from point blank to 500 yds.
