Ballistic coefficient. A selection of bullets with different shapes, and hence, different ballistic coefficients. In ballistics, the ballistic coefficient (BC, Cb) 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 ...
Very-low-drag bullet. A traditional hollow point boat tail very-low-drag rifle bullet. The jackets of these bullets are generally made out of a copper alloy (such as gilding metal or cupronickel) A very-low-drag bullet (VLD) is primarily a small arms ballistics development of the 1980s–1990s, driven by the design objective of bullets with ...
SMc cartridges were developed in an attempt to produce an efficient cartridge combining low recoil, low heat, and high velocity. [4] The 5 mm/35 SMc has produced velocities in excess of 4,800 ft/s (1,500 m/s) shooting a 30-grain (1.9 g) molybdenum disulfide-coated Berger bullet from a 28-inch (71 cm) Pac-Nor barrel, far higher than its commercial counterpart the .204 Ruger.
Mathematical discussion of rangekeeping. In naval gunnery, when long-range guns became available, an enemy ship would move some distance after the shells were fired. It became necessary to figure out where the enemy ship, the target, was going to be when the shells arrived. The process of keeping track of where the ship was likely to be was ...
Illinois Rep. Proposes Tracking Bullets With Serial Numbers Gun violence in Chicago is a problem, and one state representative has a new proposal to help — track the bullets.
Smart bullet. A smart bullet is a bullet that is able to do something other than simply follow its given trajectory, such as turning, changing speed or sending data. Such a projectile may be fired from a precision-guided firearm capable of programming its behavior. It is a miniaturized type of precision-guided munition.
A counter-battery radar or weapon tracking radar is a radar system that detects artillery projectiles fired by one or more guns, howitzers, mortars or rocket launchers and, from their trajectories, locates the position on the ground of the weapon that fired it. [1]: 5–18 Such radars are a subclass of the wider class of target acquisition ...
The Taylor KO factor multiplies bullet mass (measured in grains) by muzzle velocity (measured in feet per second) by bullet diameter (measured in inches) and then divides the product by 7,000, converting the value from grains to pounds and giving a numerical value from 0 to ~150 for normal hunting cartridges. It is proportional to the momentum ...
