A 9mm hollow point cartridge, along with unexpanded and expanded bullets. The expanded lead bullet and copper jacket are separated. 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.
An expanded 124-grain 9×19mm Parabellum jacketed hollow point. The round was originally designed to be lethal to 50 metres (160 ft), but is still lethal at longer ranges. [ 22 ] The 9×19mm Parabellum cartridge combines a flat trajectory with moderate recoil. According to the 1986 book Handloading, "the modern science of wound ballistics has ...
Overpressure ammunition. Overpressure ammunition, commonly designated as +P or +P+ (pronounced Plus-P or Plus-P-Plus), is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round.
Tracer ammunition, or tracers, are bullets or cannon -caliber projectiles that are built with a small pyrotechnic charge in their base. When fired, the pyrotechnic composition is ignited by the burning powder and burns very brightly, making the projectile trajectory visible to the naked eye during daylight, and very bright during nighttime firing.
Subsonic ammunition. Subsonic ammunitions are ammunitions designed to operate at velocities below the speed of sound (Mach 1), which at standard conditions is 340.29 m/s (1,116.4 ft/s). This avoids the supersonic shockwave or "crack" of a supersonic bullet, which, particularly for suppressed firearms, influences the loudness of the shot. [1][2][3]
The 9×18mm Makarov (designated 9mm Makarov by the C.I.P. and often called 9×18mm PM) is a pistol and submachine gun cartridge developed in the former USSR. During the latter half of the 20th century, it was a standard military pistol cartridge of the Soviet Union and the Eastern Bloc, analogous to the 9×19mm Parabellum in NATO and Western Bloc military use.
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] Neither was the .303 the first military round with this trait, the old .577 Snider bullet had a hollow core, leaving wounds known for being particularly nasty ...
