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 ...
Total metal jacket (TMJ or full metal case) bullets [1] are made by electroplating a thin jacket of ductile metal (usually copper) over a core of different metal requiring protection from abrasion or corrosion. [2] Similar full metal jacket bullets mechanically swage a thin sheet of metal over the core. The swaging process leaves an opening ...
The 7.62×54mmR originally had a 13.7 g (210 grain) "jager" round-nosed full metal jacket (FMJ) bullet. The projectile was replaced in 1908 by the 9.61-gram (148.3 gr) Лёгкая Пуля ( Lyogkaya pulya , "light bullet") spitzer bullet , whose basic design has remained to the present.
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.
The article on the F.M,J, (Full Metal Jacket) may leave the misimpression that bullet jackets were developed to comply with the Hague convention. The Hague Convention sought only to distinguish "ball" or solid bullet ammunition from hollow point or other expanding or fragmenting ammunition.
.32 ACP full metal jacket, .32 S&W Long wadcutter, .380 ACP jacketed hollow point (L-R). A wadcutter is a special-purpose flat-fronted bullet specifically designed for shooting paper targets, usually at close range and at subsonic velocities typically under approximately 270 metres per second (890 ft/s).
