The [[GW Pat.90]] ammunition is the [[5.56 mm]] standard small arms [[ammunition]] used by the [[Swiss military]] in its [[assault rifle]], the [[SIG 550]].



===History===
The GP 90 5.6 mm was designed for the [[SIG 550]] when it came into production in [[1987]], replacing the [[SIG 510]]. Previous experience of a change in standard [[rifle]] had proved that changing the [[distance of fire]] for the training [[ranges]] was more expensive than the design of a new [[ammunition]]; this prompted the design of a [[cartridge]] in the same niche as the [[5.56 x 45 mm NATO]] but able to fire nominally at [[300 metres]].

===Production and usage===

The [[cartridge]] was also designed to reduce [[pollution]] by controlling lead emissions. The [[ammunition]] is produced by [[RUAG Munition]], a company of the RUAG technology group [1]. It is a steel jacketed projectile containing approximately [[95% Pb]], [[2% Sb]], [[3% Cu]], and designed for [[terminal ballistic]] instability such that [[wounding tends]] to maim and disable rather than [[kill]] while still complying with the [[Hague Conventions]] on the Customs of [[War]].

The Gw Pat.90 is used both in the [[Swiss military]] and in [[sport shooting]]. The very high level of individual [[training]] in the [[Swiss militia]] (every single [[soldier]] bearing a [[weapon]] has to shoot for qualification once a year; see [[Gun politics in Switzerland]]) and the overall use of the Gw Pat.90 by the many [[Swiss]] citizens who shoot in competitions and for amusement has resulted in significant input on its usage. Over 1 billion cartridges have been produced as of [[2005]].
