A hollow-point bullet is a type of expanding bullet which expands on impact with a soft target, transferring more or all of the projectile's energy into the target over a shorter distance. Hollow-point bullets are used for controlled penetration, where overpenetration could cause collateral damage (such as aboard an aircraft).
These were not the first expanding bullets, however; hollow-point expanding bullets were commonly used for hunting thin-skinned game in express rifles as early as the mid-1870s. [ 12 ] [ 13 ] Also, the .303 was not the first military round with that trait since the old .577 Snider bullet had a hollow core, leaving wounds known for being ...
A ballistic tip bullet is a hollow-point rifle bullet that has a plastic tip on the end of the bullet. This improves external ballistics by streamlining the bullet, allowing it to cut through the air more easily, and improves terminal ballistics by allowing the bullet to act as a jacketed hollow point. As a side effect, it also feeds better in ...
Examples of various small-arms flechettes (scale in inches) A flechette or flèchette (/ f l eɪ ˈ ʃ ɛ t / fle-SHET) is a pointed, fin-stabilized steel projectile.The name comes from French flèchette (from flèche), meaning "little arrow" or "dart", and sometimes retains the grave accent in English: flèchette.
A spitzer bullet (from German: Spitzgeschoss, "point shot") is a munitions term, primarily regarding fully-powered and intermediate small-arms ammunition, describing bullets featuring an aerodynamically pointed nose shape, called a spire point, sometimes combined with a tapered base, called a boat tail (then a spitzer boat-tail bullet), in order to reduce drag and obtain a lower drag ...
The energy delivered by most 9mm loads allows for significant expansion and penetration with premium hollow-point bullets. Illinois State Police , border patrol , Federal Air Marshals , and United States Secret Service favored and used 115 gr (7.5 g) +P+ 9mm loads at 1,300 ft/s (400 m/s) for years with excellent results.

This engraving shows a 12-pounder U.S. shrapnel shell c. 1865. It is fitted with a Borman fuse. In the cutaway view, the dark grey is the wall of the shell, the medium grey is sulphur resin, the light grey are the musket balls, and the black is the bursting charge.
Fire from the eight machine guns of a Hawker Hurricane is shown converging to a point, then diverging. (Drawing not to scale.) In aerial gunnery, gun harmonisation, convergence pattern, convergence zone, convergence point or bore-sight point refers to the aiming of fixed guns or cannon carried in the wings of a fighter aircraft.
