These tables is highly refined and very accurate tables that give elevations in minutes of angle, elevation settings per 100 meters, remaining velocities, spin drift, flight times, angle of fall, danger space and wind deflection in inches, Mils, and Minutes of Angle. This data has been proven with many different .50 caliber rifles and other sniper weapons systems in many worldwide environments. What makes these more accurate than any table generated by computer or on the market is that a different and precise ballistic co-efficient is used every 100 meters. There are based on live firings and the data corrected to standard atmospheric conditions. Therefore the times of fight that are used in the windage formulas are more accurate.
Computer models use an average over a certain range.
This contains many errors as velocities and data around the trans-sonic flight range will be in gross error. They are designed so that the sniper can correct for all meteorological and environmental conditions the sniper may shoot in. Furthermore, more data can be developed as requested. The second half of the booklet is on special zeroing procedures for .50 caliber rifles when using these data tables.
