The good Col. hadn't even seen a 30-06 when the 9.3 was already killing things.

Betcha 10 9.3s for every 35W that has actually killed anything.

The 9.3×62mm (also known in the USA as the 9.3×62mm 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 a typical 720.0 m/s (2,362 ft/s), its 286 grain standard load balances recoil and power for effective use at up to about 250m (275 yds). The CIP Maximum Average Pressure (MAP) for the 9.3×62mm is 390 MPa (56,500 PSI). [2]

The 9.3×62mm was developed around 1905 by Berlin gunmaker Otto Bock, who designed it to fit into the Model 1898 Mauser bolt-action rifle. [2] African hunters and settlers often chose military rifles for their reliability and low cost, but governments fearful of colonial rebellions often banned military-caliber bolt-action magazine rifles and their ammunition. The 9.3×62mm was never a military cartridge and so never had this problem. Mausers in 9.3×62mm were inexpensive and reliable, too, so their popularity in Africa grew quickly and became widespread.

The rifle "behind the door" in the German colonies.
