In this instance, heavier bullets are loaded in standard ammunition, which reduces muzzle velocity below the speed of sound. As an example, the very common 9×19mm Parabellum standard military round is a 7.5 g (116 gr) bullet at velocities typically around 360 m/s (1,200 ft/s). Subsonic loads for 9×19mm Parabellum commonly use 9.5 g (147 gr ...
Smokeless powder loads, called "high speed" or "high velocity", were offered by the major ammunition makers, giving a typical velocity increase of 8% (1,200 feet per second (370 m/s) to 1,300 feet per second (400 m/s)) while still using the standard 40 gr (2.6 g) solid or 36 gr (2.3 g) hollow-point lead bullet.
Bullets used in many cartridges are fired at muzzle velocities faster than the speed of sound [10] [11] —about 343 metres per second (1,130 ft/s) in dry air at 20 °C (68 °F)—and thus can travel substantial distances to their targets before any nearby observers hear the sound of the shots.
Detonation velocity is the speed with which the detonation shock wave travels through the explosive. It is a key, directly measurable indicator of explosive performance, but depends on density which must always be specified, and may be too low if the test charge diameter is not large enough.
It has a long heavy bullet with a semi-armor-piercing iron or mild steel core and a gilded steel jacket. After the Vietnam War it was replaced by the M80 ball cartridge as the standard round. Data contained in TM 9-1005-298-12 mentions the approximate maximum range of 3,820-metre (4,180 yd) at 856.2-metre-per-second (2,809 ft/s) muzzle velocity ...
The M2 ball specifications required 2,740 feet per second (835.2 m/s) minimum velocity, measured 78 feet (24 m) from the muzzle. [23] M2 ball was the standard-issue ammunition for military rifles and machine guns until it was replaced by the 7.62×51mm NATO round in 1954.
The bullet itself masses 0.2 grams (3 grains), and is estimated to have a normal muzzle velocity of 200 metres per second (660 ft/s), resulting in a muzzle energy of 4 joules (3 ft-lbs). [4] For perspective, an average person's punch measures 10-15 joules (7-11 ft-lbs), meaning that the round has less energy than a punch.
