How much yerds are you away
Note: I am not zeroed for 100 yards. Note how high I centered my group at 25 yards.@100 yards, my group was 7" high. This is what I wanted, since i want it zerod around 300 yards. If you want a 100 yard zero and you center your group, Ie: Where Point of aim and point of impact are the same @ 25 yards, with a 55 grain 5.56 bullet, you should be around 5 inches high @ 100, 2 " low at 25 yards. Make sure you tweak you rifle at a range for the zero distance you want. Check the ballistic drop tables for you bullet, velocity and range. This method is designed to get you on paper, especially windage wise but you still have to make adjustments for the zero you desire.
