In ballistics, the ballistic coefficient (BC, C b) of a body is a measure of its ability to overcome air resistance in flight. [1] It is inversely proportional to the negative acceleration: a high number indicates a low negative acceleration—the drag on the body is small in proportion to its mass.
Telescoping stock or collapsing stock: A stock on a firearm that can telescope or fold in on itself to become more compact. Telescoping stocks are useful for storing a rifle or weapon in a space that it would not normally fit in. Terminal ballistics: A sub-field of ballistics, the study of the behavior of a projectile when it hits its target. [32]
Within external ballistics, when the sectional density of a projectile is divided by its coefficient of form (form factor in commercial small arms jargon [3]); it yields the projectile's ballistic coefficient. [4] Sectional density has the same (implied) units as the ballistic coefficient.
Ballistics is the field of mechanics concerned with the launching, flight behaviour and impact effects of projectiles, especially weapon munitions such as bullets, ...
[26] [9] The s.S. ball projectile with a 5.9 millimetres (0.23 in) long 6° 25′ 51″ boat tail was designed for long range use and offered the best aerodynamic efficiency and external ballistic performance of any standard rifle bullet used during World War II, with a G1 ballistic coefficient between 0.593 and 0.557 (ballistic coefficients ...
What does it mean to own a stock? Owning a stock is a little different than if you owned 100 percent of a private business. Owning a share of stock gives you a partial ownership stake in the ...
The FMJ cartridge has a Copper-Zinc alloy case and uses a double base propellant. The bullet is a 4.1 g (63 gr) tombac jacketed FMJ projectile with a G1 ballistic coefficient of 0.331 (ICAO) / 0.337 (Army Metro). The projectile contains approximately 95% Pb, 2% Sb, 3% Cu, and was designed for terminal ballistic instability.
The average stock market return of about 10 percent doesn’t factor in the impact of inflation, which has historically been around 2 to 4 percent annually depending on the time period.
