External ballistics describes the movement of the fired bullet or explosive in the air, including any factors affecting it.
I understood external ballistics at a time when most boys my age were memorizing ball scores.
The speed of sound, altitude, humidity, and temperature all affect drag because they are components of air density, and since atmospheric conditions change often this can ultimately cause bullet strike to be higher or lower than expected, according to Professor Gilbert Ames Bliss in Mathematics for External Ballistics.
Match bullets have thin copper jackets that are made to optimize external ballistics, while hunting bullets (and their thicker jackets, cannelures and bonding efforts) focus almost exclusively on terminal effects.

Anyone who takes up handloading is literally forced to learn more about internal and external ballistics than he or she ever thought they wanted to know.
Accurate rifles are as common as iPods these days, but interesting rifles have something to teach us, if we're willing to learn--whether about rifle history or external ballistics or whatever.
This tail, with its larger base area, improves the projectile's external ballistics by lending high flight stability to the bullet.
It also computes all necessary external ballistics based on an instantly changeable zero range -- data such as bullet path, wind deflection, remaining velocity and energies -- then computes a "power factor" based on momentum.
The bullet's torpedo-shaped tail with its large surface area improves the bullet's external ballistics by lending a high degree of flight stability.
The photo they forwarded to me was one of a rifle ammunition box, and by closely examining it, I find that it shows the external ballistics of some 16 rifle cartridges, from the 6mm Remington to the .
