The 8×56mmR or 8×56mmR M30S (C.I.P. civil designation) cartridge was adopted in the year 1930 by Austria, in 1931 by the Kingdom of Hungary and in 1934 by the Kingdom of Bulgaria as a replacement for the 8×50mmR Mannlicher cartridge.
It was originally created for the Steyr-Solothurn light machine gun as the M30. Later the cartridge was adopted for use in rifles in 1931 as the M31 to replace the 8×50mmR Mannlicher cartridge. The updated cartridge coincided with an update to the Steyr-Mannlicher M1895 rifle in which the barrel length was reduced and the chamber re-cut to accept the new cartridge, and was the cartridge chosen by Hungary for the 35M rifle as a replacement for the Mannlicher M1895. The 8×56mmR was also used in updated versions of Austrian and Hungarian machine guns such as the Solothurn 31M and Schwarzlose 07/31M. From 1934 on it was the standard military cartridge of Kingdom of Bulgaria.
This ammunition was made at a variety of plants as well as countries, including Austria, Germany, Bulgaria and Czechoslovakia.
The 8×56mmR is currently produced by Hornady and Prvi Partizan for commercial sales. It is no longer in use by any organized military forces. While many Stutzen Model 1895/30 were brought into the United States and sold at retailers such as Big-5, the price of the round still remains much higher than most other surplus rifle rounds such as 7.62×54mmR and .30-06 (7.62×63mm), making 8×56mmR very uneconomical to shoot for the average shooter.
