History
Developed in the early 1930s to upgrade the aging Austro-Hungarian Mannlicher M1895 rifles to a more powerful cartridge. The new case was longer and used a larger-diameter bullet, requiring a barrel liner conversion on M1895 rifles. Hungary adopted it as the standard rifle cartridge and fielded it through WWII. Hungarian military surplus ammunition in 8x56mmR is the most commonly encountered today. Sellier & Bellot and Hornady produce factory ammunition.
