Do as allyooper said, We started at 25 yds , I have an 06, so i sight in at 25 yds were the bullet hits 3/4"to 1/2" low. Then move it out to 100 yds. Just make one move after 25 yds, if you stop at 50 you will be making adjustments you don't need. Now at 100 , I put the bullet dead center on the bulls eye , then i set it to hit 1 1/2" to 2 " high at 100. Good luck.
