 This cartridge has a 16.6 g (256 gr) pointed boat-tailed FMJ bullet with steel core and achieves a muzzle velocity of 770 m/s (2520 ft/s).The 9SN cartridge should be able to defeat body armour at ranges up to 600 metres (660 yd).The ballistic performance of the 9.3x64mm Brenneke is similar to the .375 H&H Magnum while being smaller and using less propellant - it has 8% less case capacity, making it a more modern, efficient design.
