25 yards is okay for getting close but you must go to 100 yards and usually want to be one to two inches high depending on caliber and bullet weight. When sighting in at 25 yards wher it hits at other ranges is going to depend a big part on how high your scope is mounted on the gun the higher the scope the further off you will be. example I have two 06s one with see through sites sighted in at 25 I found it was 4 inches high at 100 and 11 inches high at two hundred. The other with low rings 1 1/2 high or so at 100 and almost right back on at 200.
