Re: Mauser 98 from 1925.

Couple of points made by 4seventy and Daryl S I think need a little clarifying.

The 10.75 x 68 and the 404 Jeffery as loaded by the Germans were one and the same calibre, the bullet diameter for both these cartridges being 0.423” or 10.75mm (the .404 aka the 10,75 x 73).

The 10.75 x 68 (aka 10.75 Mauser) was only ever factory loaded with 347gr bullets while the .404 was factory loaded with 400gr although a high velocity 300grloading was produced for this cartridge at one stage.

The 10.75 x 68 can be loaded with a 400gr bullet at higher pressures to match the old low pressure cordite .404 loading but note that the .404 factory loads using the more modern cordite and nitrocellulose grained powders were upped in velocity by a 150-200fps.

The 10.75 x 68 can never catch up to the modern .404 both in factory loads or reloads, an impossibility based on the quite different case sizes.

If loading the 10.75 x 68 with the 400gr bullet the OAL will be out of spec if crimping into the cannelure, the 10.75 x 68 having an OAL of 3.165” loaded with its 347gr bullet, and requiring an OAL of 3.320” if crimping a 400gr to the cannelure. While acknowledging that 4seventy is showing an example of this 68mm cartridge loaded with a 400gr bullet, a longer loaded 10.75 x 68 cartridge could present difficulties with throat length and magazine length considerations.

With a well made 347gr bullet the 10.75 x 68 can still be increased in performance with modern loads and higher pressures and should perform well on big game though it will never make it into the realm of the .404.
