Weather
The weather element that allows easier recognition of "bullet trace"
What is humidity?
The theory that represents the only "constant" in the shooting discipline.
What is gravity?
The force dependent on the location relative to the equator, which affects a projectile's horizontal travel in flight.
What is the Coriolis force?
The fundamental of ballistics that can induce inconsistencies in verticle dispersion of the point of impact due to irregular vibrations.
What are the rifle's harmonics?
This weather element can make one's projectile skew horizontally from the intended point of impact.
What is wind?
The centrifugal force generated by the projectile rotating on its axis causes this common effect on bullet flight at extended ranges.
What is "spin drift?"
The variable that coincides with Coriolis force and determines the degree of effect on horizontal travel of a projectile throughout its flight, measured in degrees azimuth.
What is the direction of fire?
The element of ballistics that begins when a projectile leaves the rifle muzzle.
What are the external ballistics?
You calculate for this when determining projectile "drop" over the distance of its flight path.
What is barometric pressure?
This variable affects the actual linear distance traveled by a projectile in flight, and uncorrected results in verticle dispersion noted by potential target "misses."
What is the verticle angle of fire?
This physical location variable affects a projectile's vertical dispersion in flight due to air density, measured in feet above sea level.
What is the altitude?
The flight path of projectiles noted by the perceived arced travel.
What is a parabolic trajectory?
One must consider this when determining elevation adjustment for target shooting at extended ranges.
What is ammunition or powder temperature?
Shooting from a location on the equator and shooting due east or west has this effect on a projectile's flight.
What is verticle dispersion?
The effect on the projectile distance traveled if the shooter's location is 500 feet above the intended target
What is a reduced actual horizontal range?
The numerical representation for a projectile's ability to move efficiently through the air.
What is a bullet's ballistic coeficient?
This element can affect one's ability to clearly identify the target.
What is daylight?
This controls the distance at which a projectile in flight may travel.
What is the projectile's velocity?
The elements affecting the prominence of Coriolis force.
What are the longitude location and direction of fire?
The remaining velocity of a projectile in flight affects this.
What is a projectile's terminal energy?
