Federal's TSS loads in the .410, 20and 12-gauge represent a quantum shift in the way we understand the external ballistics
of shotgun payloads.
Its effectiveness was a consequence of its ammunition, which excelled in its long range accuracy, external ballistics
, stopping power, and lethality.
The new 173-grain Ml load provided greater range and better external ballistics
compared to the old M1906 load.
Now, for specifics: Trajectory (external ballistics
)--An eight-inch kill zone is a reasonable average for North American big-game animals.
The three major stages of a bullet's performance are in bore (internal ballistics), down range (external ballistics
) and terminal (usually only applicable to hunting bullets).
describes the movement of the fired bullet or explosive in the air, including any factors affecting it.
Of the .223 offering in the new ammunition, Johnson said, "It replicates the standard .22-250 Remington external ballistics
from a .223.
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
. To conceptualize atmospheric conditions affecting bullet behavior, it may be useful to think of air as a fluid.
A torpedo-shaped tail improves external ballistics
. At the muzzle the load produces 2,755 fps.
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.
The 115 grain weight in .277 provided the best combination of internal and external ballistics
desired in a combat cartridge.
