Many still uses it, but in the old time it was used all over africa for everything. It wasnt up to the same potantial as the 404 but with modern loads it is as Peter states, possible to duplicate the "old" 404 load.

If you lived or was going to africa in the beginning of 1900, you took a long look at the london mausers, then a quick look at your wallet, and bought a german built mauser chambered for the 10,75x68.
