The 8mm Roth–Steyr is a military centerfire pistol cartridge adopted by the Austro-Hungarian cavalry in 1907 for the Repetierpistole M7—the first self-loading pistol adopted by a major military power. The cartridge headspaces on the mouth of the case. Ammunition was typically packaged in a unique ten-round charger. Austrian military production contained greased un-plated steel-jacketed bullets. A few private firms in Austria manufactured ammunition with cupro-nickel-jacketed bullets.[1]
