Heckler and Koch developed 4.6x30mm ammo in 1999. The round was introduced in 2001 as the ammunition of choice for its MP7 PDW (personal defense weapon). According to HK's website, "the MP7 represents a new generation of enhanced-performance submachine guns that bridge the gap between assault rifles and conventional submachine guns. Developed as a genuine personal defense weapon, it far exceeds the NATO requirements profile." The cartridge's development attempted to reduce weight so shooters could carry more ammo, and yet give excellent penetration, particularly against targets wearing body armor.
The 4.6x30 HK shell itself looks very much like most rifle cartridges with bottle necks. The service bullet, however, is quite different. The core of the bullet is not the conventional lead with a gilding metal casing; rather, the bullet's core is steel with a brass jacket although some ammunition manufacturers offer "solids" made of a copper-zinc alloy. Ammunition makers also offer a number of variations in ammunition construction for training and other purposes. For example, for training purposes, a leadless, bronze-sintered powder bullet has been developed enabling pollution-free training exercises.
