Numbers of mils in 360 degrees
6283

Mil Relation Formula
Height of object in inches x 27.8 (25.4) / mils read = range in yards (meters)

Lead Formula for moving targets
Time of flight (sec) x Speed of target (fps) = Lead from centermass in feet (full value lead)

Basic Wind Formula
 Range (y/100) x wind velocity / Constant = MOA hold
 .223 Constant = 10
 .308 constant= 15

Conversion of MOA to Mil
MOA Value / 3.438 = Mil Value

Mil Click Value @ 100m
1 click = .1 mil = 1 centimeter

number of radians in a circle
6.2832

convert MOA to MILS
moa (0.2909) = Mils

Wind Formula (MOA)
Range (hundreds) X Wind (MPH) / Constant (15) =
Wind Adjustmrent (MOA's)
*Adjust answer commensurate with the value of the wind

Convert MOA hold to mils
MOA / 3.5 = mil hold





Deterministic Variables
variables that can be measured and accounted for (ex; gravity drop, spin drift)

Nondeterministic variables
variables that cannot be directly measured and affect the trajectory of the bullet (ex; wind, different muzzle velocities

accuracy
the measure of how close your shots are to the center of the target

precision
how tightly the shots are grouped together.

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

Attributes that determine BC
 Weight
 Cross sectional area
 Form Factor

12" measeurements on the human body (3)
 top of the head to the collarbone
 bottom of chin to center mass
 shoulder to elbow

To convert centimeters to inches
multiply the inches by 2.54

To convert inches to centimeters
multiply the inches by 0.3937

four target indicators
 1. Visual
 2. Auditory
 3. Tactile
 4. Olfactory

Kinetic Energy is proportionate to what two bullet characteristics?
mass and velocity

Lag Time
The difference between time of flight and time of flight in a vacuum

Lag time equation
Tlag=toftof (vac)

Wind deflection is directional proportionate to?
lag time and crosswind speed

wind delfection formula
WD= Ws(Tlag)

Lag Time is affected by two things the shooter has control over:
BC and muzzle velocity

What determines the wind sensativity if a bullet?
Muzzle velocity and BC

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)

wind gradient
the tendency for wind to move faster farther off the ground

point forward flight
means that the nose of the bullet is always pointed straight into the oncoming airflow like a weather vane.

in order to get better at hitting targets, you must........
....understand what causes us to miss targets.

precision is expressed by shooters as:
group size

Accuracy is....
centering the group or shot

Conversion formula for MPH to FPS:
MPH (1.4667) = FPS

Moving Target Formula for Lead in Feet
TOF (sec) x Target Speed (fps)=Lead (Feet)

Moving Target Formula for Lead in inches
TOF(sec)xTarget Speed(fps)x12= Lead (inches)

Convert Mils to MOA:
Mils x 3.4=MOA

1 centimeter = how many millimeters?
10


Convert centimeters to inches formula
multiply inches by 2.54

one inch = ? centimeters
2.54

convert inches to centimeters formula
multiply inches by .4
(.3937)


100 yards = ? meters
91.44

convert yards to meters formula
multiply yards by .9144


A primer is made up of three components:

Parallax
the apparent shift in anobjects position when you look at it from a different vantage

Cadaveric Spasm
The momentary convulsion or spasm in which the suspect's muscles tighten suddenly

Caliber
 The diameter of the lands in a rifle barrel
 the diameter of a bullet expressed as a decimal fraction of an inch

cannelure
the crimping groove around a bullet

Density Altitude is a function of:
 temperature
 elevation
 barometric pressure

False hide
used to distract susepct from actual shooting position

Four types of Hostage Rescue (most to least desirable)
 Negotiations
 Open Air Takedown
 Vehicle Assault
 Stronghold Assault

Four Basic Hostage Taaker profiles
 Mentally ill
 Domestic disturbance
 Criminal
 Terrorist

Four types of deployment on HR
 Opposite Corners
 L Shape
 VShape
 Side by Side

Three parts of the brain stem
 Mid Brain
 Pons
 Medullla Oblongata

Target Speed for: (fps)
Slow Patrol:
Fast Patrol:
Slow Walk:
Fast Walk:
Run:
 Slow Patrol: 1fps
 Fast Patrol: 2fps
 Slow Walk: 4fps
 Fast Walk: 6fps
 Run: 1012fps

Formula: convert lead in feet to inches
Lead in Feet x 12 = lead in inches

Convert lead in inches to Mils formula:
 lead in inches / range (yards/100)
  =Mil Lead
 3.6

Formula for target that is moving INTO the wind
Target lead + wind hold = Total Lead

Formula for target that is moving WITH the wind
Target lead  wind hold = total lead

Three methods of engaging moving targets
 Tracking
 Trapping
 Snap shot

1 circle = how many:
degrees
mils
minutes
 360 degrees
 6400 mils
 21600 moa

Target Indicator
Anything that the Sniper does or fails to do that will reveal his position, presence, or passage to the enemy.

3 types of target indicators:
 Sound
 Movement
 Improper Camo


Factors to consider; moving targets
 wind affects
 angle of targets movement
 range
 speed of target
