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) =

10. Convert MOA hold to mils
MOA / 3.5 = mil hold
11. 1 meter = ? yards
1.0936
12. 1 yard = ? meters
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
20. Attributes that determine BC
• Weight
• Cross sectional area
• Form Factor
21. 12" measeurements on the human body (3)
• -top of the head to the collarbone
• -bottom of chin to center mass
• -shoulder to elbow
22. To convert centimeters to inches
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
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)
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
41. Convert Mils to MOA:
Mils x 3.4=MOA
42. 1 centimeter = how many millimeters?
10
43. one centimeter = inches?
• .4
• (.3937)
44. Convert centimeters to inches formula
multiply inches by 2.54
45. one inch = ? centimeters
