A full metal jacket (FMJ) bullet is a small-arms projectile consisting of a soft core (often lead) encased in an outer shell ("jacket") of harder metal, such as gilding metal, cupronickel, or, less commonly, a steel alloy. A bullet jacket usually allows higher muzzle velocities than bare lead without depositing significant amounts of metal in ...
The 9×19mm Parabellum (also known as 9mm Luger, 9mm NATO or simply 9mm) is a rimless, centerfire, tapered firearms cartridge. Originally designed by Austrian firearm designer Georg Luger in 1901, [ 6 ] it is widely considered the most popular handgun and submachine gun cartridge due to its low cost, adequate stopping power and extensive ...
The new full metal jacket bullets tended to penetrate straight through a target causing less internal damage than a bullet that expands and stops in its target. This led to the development of the soft-point bullet and later jacketed hollow-point bullets at the British arsenal in Dum Dum , near Calcutta around 1890.
9mm Browning Long is similar to 9×19mm Parabellum, but has a slightly longer casing and is semi-rimmed; the cartridge headspaces on the rim. The cartridge was developed by FN to be used in the blowback-operated Model 1903, a pistol designed using the same Browning patent as the Colt 1903. Using a more powerful cartridge, such as the 9×19mm ...
JSP is a semi-jacketed round as the jacket does not extend to the tip. The notches on the tip of the JHP assist in the expansion of the bullet on impact with soft tissue. Jacketed flat point (JFP) may describe either soft-point or full metal jacket bullets with a flat, rather than a rounded front.
Hawaii state law prohibits the "manufacture, possession, sale, barter, trade, gift, transfer, or acquisition of ... any type of ammunition or any projectile component thereof coated with teflon or any other similar coating designed primarily to enhance its capability to penetrate metal or pierce protective armor."

The jacket may ricochet, but should have reduced range without the weight of the frangible core. [5] Frangible hollow-point bullets may penetrate clothing, drywall, and light sheet metal; but often disintegrate upon striking glass. [6] Hard targets may be damaged by frangible bullets. Extent of damage increases with velocity of bullet impact.
