Ammunition, Missiles and precision weapons

A rimmed, straight-taper case of brass or nickel-plated brass, Boxer or Berdan primed. Various types and weights of bullet have been produced. The most common factory loading for many years was a 10.23 g soft-pointed bullet, but in recent years the 8.1 g JHP pattern has achieved widespread use for both law enforcement and personal defence. Introduced in 1935 by Smith & Wesson, this virtually became the standard law enforcement round in the USA by the 1960s. Whilst the calibre is the same as the 0.38 Special

cartridge, the nomenclature was changed to 0.357 (the exact, rather than the nominal calibre) to distinguish this more powerful round. In addition the case is about 2.5 mm longer than other 0.38 cases, preventing it from being chambered in older revolvers that may not be strong enough to withstand the extra pressure. Applications include suitably chambered revolvers.
