[QUOTE="Guest, post: 119818"] There are three methods of utilizing the Angle Co-Sine Indicator and one is more accurate the other. 1) The most accurate method is to input the co-sine number or angle into your ballistic software; i.e. Night force Ballistic Targeting software ($70.00). 2) Method two is called the Improved Rifleman Method. This is where you multiply the co-sine number to your hold as depicted on your data card. (600 yards = a hold of 11.25 moa.) (.7 X 11.25moa = 7.87 moa). 3) Method three is called the rifleman Method. This is where you multiply the co-sine number to your distance to target. (.7 X 600 yards. = 420 yards). The reason that the ballistic targeting software is the most accurate method is because the software takes into account the fact that the bullet is still traveling the full distance to target, with a similar time of flight. Those factors commingled with the bullets own unique deceleration curve can be up to 8 moa more accurate than the rifleman method when shooting on steep inclines and out at further distances. A 600 yards shot on a 45 degree angle up at a big horn would be 7 moa, not 11.25. (According to Night Force’s Ballistic targeting Software). This difference if uncorrected would equal a high poi of 26.6”. [/QUOTE]
