The Patrone 88 (cartridge 88) or M/88 is a rimless bottlenecked rifle cartridge. It was a first-generation smokeless propellant cartridge designed by the German Gewehr-Prüfungskommission (G.P.K.) (Rifle Testing Commission) as the then-new smokeless propellant introduced as Poudre B in the 1886 pattern 8×50mmR Lebel started a military rifle ammunition revolution.

The Patrone 88 cartridge was loaded with 2.75 g (42.4 gr) of single-base (based on nitrocellulose) smokeless powder. The cartridge was based on a Swiss design and was loaded with a 8.08 mm (0.318 in) diameter 14.6 g (225 gr) round-nose full metal jacket bullet that was cupronickel plated and reached a muzzle velocity of 620 m/s (2,034 ft/s). The bullet core consisted of 95% lead and 5% antimony. It served as parent cartridge of several 8×57mm rimless and rimmed rifle cartridges.
