History
Developed by Wilhelm Brenneke in 1927 as a powerful hunting cartridge for German bolt-action rifles without the need for a full magnum-length action. The 9.3x64 delivers energy comparable to a .375 H&H with 286-grain bullets, making it suitable for dangerous game. More common in Germany and Austria than in the Anglophone world; primarily loaded by RWS and Norma.
