The 9.3x64mm Brenneke is a rimless, bottlenecked rifle cartridge developed in Germany by Wilhelm Brenneke in 1927. It's renowned for its powerful performance and is particularly popular among European hunters. The cartridge was originally designed for big game hunting and is effective for taking down large and dangerous game such as moose, bear, and African big game species like buffalo.
Key specifications include a bullet diameter of 9.3mm (.366 inches), overall length of 84mm, and typical bullet weights ranging from 230 to 300 grains. The cartridge can deliver high muzzle energy and penetration, making it suitable for long-range hunting in woodland and mountainous terrains. The 9.3x64mm can achieve muzzle velocities of approximately 2,600 to 2,700 feet per second (fps), depending on the bullet weight and load.
Its design offers an effective balance of power and recoil, providing a potent alternative to cartridges like the .338 Winchester Magnum and the .375 H&H Magnum. However, it is less commonly encountered outside of Europe compared to those rounds.
Use cases for the 9.3x64mm include hunting large, potentially dangerous animals due to its excellent stopping power and deep penetration capabilities.
