The 9.3x62 mm calibre was developed by German gunsmith Otto Bock and introduced in 1905. Bocks cartridge was intended for the Mauser 98 rifle, considered to be the sturdiest of its day; this has given rise to the misnomer "9.3x62 Mauser". This powerful cartridge was first used mainly in Germany and the Netherlands and their respective colonies for big-game hunting. In France, it is seen as one of the best calibres for driven hunts against big game. It started to come to prominence in the USA in the early 1990s and its success continues to grow. The weight of the actual 9.30 mm diameter bullets ranges from 11.60 grams (179 grains) to 21.00 grams (324 grains), a real feat of adaptability. Its metric notation is due to its European origin; its 62-mm-long case is based on the 7x64 mm case with the neck widened to hold a 9.30 mm bullet, and can contain a significant powder load in the region of 5.063 cm³. Modern powders generate high ballistic performances from this calibre during driven hunts, in which it excels. The average muzzle velocity is between 2,297 and 2,887 fps depending on the bullets reference mass. The kinetic energy developed at 50 metres on driven shoots is never less than 3,800 Joules. Winchester offers a load with the 18.53-gram (286-grain), 2,359-fps Power Point bullet.
