  1. Numbers of mils in 360 degrees
    6283
  2. Mil Relation Formula
    Height of object in inches x 27.8 (25.4) / mils read = range in yards (meters)
  3. Lead Formula for moving targets
    Time of flight (sec) x Speed of target (fps) = Lead from center-mass in feet (full value lead)
  4. Basic Wind Formula
    • Range (y/100) x wind velocity / Constant = MOA hold
    • .223 Constant = 10
    • .308 constant= 15
  5. Conversion of MOA to Mil
    MOA Value / 3.438 = Mil Value
  6. Mil Click Value @ 100m
    1 click = .1 mil = 1 centimeter
  7. number of radians in a circle
    6.2832
  8. convert MOA to MILS
    moa (0.2909) = Mils
  9. Wind Formula (MOA)
    Range (hundreds) X Wind (MPH) / Constant (15) =

    Wind Adjustmrent (MOA's)

    *Adjust answer commensurate with the value of the wind
  10. Convert MOA hold to mils
    MOA / 3.5 = mil hold
  11. 1 meter = ? yards

    0.9144
  13. 1 mil = ? MOA
    3.4377
  14. 1 MOA = ? mils
    0.2909
  15. Deterministic Variables
    variables that can be measured and accounted for (ex; gravity drop, spin drift)
  16. Non-deterministic variables
    variables that cannot be directly measured and affect the trajectory of the bullet (ex; wind, different muzzle velocities
  17. accuracy
    the measure of how close your shots are to the center of the target
  18. precision
    how tightly the shots are grouped together. 
  19. point blank range
    the distance between a firearm and a target of a given size such that the bullet in flight is expected to strike the target without adjusting the elevation of the firearm

    multiply the inches by 2.54
  23. To convert inches to centimeters
    multiply the inches by 0.3937
  24. four target indicators
    • 1. Visual
    • 2. Auditory
    • 3. Tactile
    • 4. Olfactory
  25. Kinetic Energy is proportionate to what two bullet characteristics?
    mass and velocity
  26. Lag Time
    The difference between time of flight and time of flight in a vacuum
  27. Lag time equation
    T-lag=tof-tof (vac)
  28. Wind deflection is directional proportionate to?
    lag time and crosswind speed
  29. wind delfection formula
    WD= Ws(Tlag)
  30. Lag Time is affected by two things the shooter has control over:
    BC and muzzle velocity
  31. What determines the wind sensativity if a bullet?
    Muzzle velocity and BC
  32. wind gradient
    the variation of wind speed with height above ground

    (the higher you go the faster the wind, therefore you should consider the maximum ordinate of the round when factoring in wind deflection)
  33. wind gradient
    the tendency for wind to move faster farther off the ground
  34. point forward flight
    means that the nose of the bullet is always pointed straight into the oncoming airflow like a weather vane.
  35. in order to get better at hitting targets, you must........
    ....understand what causes us to miss targets.
  36. precision is expressed by shooters as:
    group size
  37. Accuracy is....
    centering the group or shot
  38. Conversion formula for MPH to FPS:
    MPH (1.4667) = FPS
  39. Moving Target Formula for Lead in Feet
    TOF (sec) x Target Speed (fps)=Lead (Feet)
  40. Moving Target Formula for Lead in inches
    TOF(sec)xTarget Speed(fps)x12= Lead (inches)
  41. Convert Mils to MOA:
