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.
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point.. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name.
Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
The neck is sized for .224 caliber bullets. 224 Valkyrie, Uses 6.8 SPC cases, trimmed shorter, and the shoulder re-formed at a lower location due to being designed for using relatively long "high BC" (Ballistic Coefficient) bullets. The neck is sized for .224 caliber bullets.
Cartridge, caliber 7.62mm, NATO, ball, special, M118LR: 175-grain (11.3 g) 7.62×51mm NATO match-grade round specifically designed for long-range sniping. It uses a 175-grain (11.3 g) Sierra Match King hollow point boat-tail bullet with a ballistic coefficient (G7 BC) of 0.243. [94] Produced at Lake City Army Ammunition Plant.
Cartridge, Caliber 5.56 mm, Tracer, XM778: 5.56×45mm tracer cartridge mated with the XM777 Semi-Armor-Piercing cartridge. Cartridge, Caliber 5.56 mm, Ball, M855 [Green tip]: 5.56×45mm 62-grain FN SS109-equivalent ball cartridge with a steel penetrator tip over a lead core in a full copper jacket. It is designed to penetrate lightly armored ...
This cartridge is more powerful than its parent, especially in killing power on large game. However, with much wider availability, and the higher BC (ballistic coefficient) .30 caliber bullets of today, the power gap between the two cartridges has been decreased.
An example of such a special .416 Barrett very low drag extreme range bullet is the German CNC manufactured mono-metal 27.5 gram (424 gr) .416 Barrett MSG (G1 BC ≈ 1.103 – this ballistic coefficient (BC) is calculated by its designer, Mr. Lutz Möller, and not proven by Doppler radar measurements).
