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.
The advantages are not just that you can use sharp-nosed bullets safely but that those bullets can have better external ballistics, lower drag, flatter trajectories and better-controlled expansion.
277 provided the best combination of internal and external ballistics desired in a combat cartridge.
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.
Sierra has now further refined this bullet with the addition of a polymer tip which improves upon the external ballistics by significantly increasing ballistic coefficient from .
He should understand basic internal and external ballistics and know how to evaluate a spent cartridge case and recognize problems such as high pressure, bulged cases and dented case mouths.
62x54R--whose external ballistics approximated those of our own service cartridge, the .
The result has been new designs that enhance both external ballistics and terminal performance.
