From Wikipedia, the free encyclopedia:
"The 9.3x62mm (in the USA also known as the 9.3 x 62 Mauser) is an 'all-around firearms cartridge' suitable for hunting larger species of animals in Africa, Europe, or North America. It was introduced by Otto Bock in 1905. At 730 m/s (2400 ft/s), its 18.5-gram (285 gr) standard load balances recoil and power for effective use at up to about 250 m (270 yards). The CIP Maximum Average Pressure (MAP) for the 9.3x62mm is 390 MPa (56 500 PSI)
The 9.3x62mm was developed around 1905 by Berlin gunmaker Otto Bock, who designed it to fit into the Model 1898 Mauser bolt-action rifle. African hunters and settlers often chose military rifles for their reliability and low cost, but governments fearful of colonial rebellions often banned them and their ammunition. The 9.3x62mm was never a military cartridge and never had this problem. Mausers in 9.3x62mm were inexpensive and reliable, so their popularity in Africa grew quickly.
The 9.3x74R is a rimmed 9.3 mm cartridge that evolved from the 9.3x72 black powder cartridge. The energy levels of the 9.3x62 and 9.3x74R cartridges are similar but in developmental terms are distinct as the cartridges are unrelated. The rimmed cartridge is slightly longer, allowing for lower pressure in the case while retaining muzzle velocity.
The 9.3x62mm is ideal for eland, zebra, giraffe and wildebeest, and most who hunt in Africa consider it a viable all-around cartridge comparable to the .338 Winchester Magnum, the 9.3x64mm Brenneke, the .375 H&H Magnum and the .404 Jeffery. The 9.3x62mm has taken cleanly every dangerous species on the continent. Though it is of smaller bore than the legal minimum for dangerous game in most countries, the .375 H&H, many countries specifically make an exception for the 9.3x62mm. The 9.3x62mm is considered adequate for European and North American game that may become dangerous, such as feral hogs and the great bears. Sambar hunters in Australia are turning to the 9.3x62mm, the deer hunter's favourite rifle has changed due to the Howard (Federal) Government's ban on self-loading rifles (1994), a great many Sambar hunters were well catered for by the various makes of self-loading rifles that were available in .30-06 and like calibres, when the self-loaders were banned there was a buy-back and suddenly thousands of deer hunters were looking for bolt-action rifles that delivered one-shot knockdown power on Sambar deer, the 9.3x62mm calibre has proven to be well up to that task and now rifle manufacturers are including the calibre in their standard model lineup (Sako is a good example) and most gunshops carry factory loads in packets of 20 rounds although the price is still high at about AU$35.00 per 20 compared to .30-06 at about $25.00 Aus per 20. For the handloader most every major manufacturer of bullets offer something for the 9.3mm. Barnes offers both their TSX bullets as well as their excellent Banded Solids in both 250 and 286 grains, Nosler offers the Partition and Accubond. Swedish company Norma offers several bullets in 9.3mm including it's bonded Oryx. As well Hornady and Speer both offer conventional softpoints. Swift offers their A-Frame in 250 and 300 grain weights. Australian bullet manufacturer Woodleigh, catering to the dangerous game hunter, offers it's bullets in the widest range or weights and profiles ranging from a 250 grain softpoint to the buffalo-flattening 320 grain solid."
