These scopes have about 90 moa of internal adjustment windage and elevation usually about half above and half below unless you use a plus moa base from Badger Ordnance.
example 168 gr Sierra matchking balistic coeffecient at 2650 ft per sec is .462
From what I understand so far you have the M2 (short) knobs that have built in balistic compensation. M2 knobs are 1/2 minute of angle per click where the M1 knobs are 1/4 minute of angle per click. At 100 yds one minute of angle is essentially one inch at two hundred yards one minute of angle is essentially 2 inches and so on one minute of angle 300 yds is 3 inches, 400 yds one minute of angle is 4 inches. So if you sight in at 100 yds ZERO and you are using 1/2 moa per click here is your chart, just remember that that 1/2 inch at a hundred is not 1/2 inch at 400 it is 1/2 moa or 2 inches think of it as parts of a circle the farther out you go the bigger the piece of the pie. If you want custom knobs for different weight bullets order from Kenton Ind. the link is above.
