I am aware of that. From what I have read on the subject it seems as though given the properties of the steel that the Mauser brother were working with they relied on mass and design to handle the pressures involved. But I have also read that many of these actions were rebarreled to 7.62x51 NATO post by the Spanish, so I assume that, subject to direct experience of those who have gone down this path before me, it can be done if one is armed with the rite information.
The Spanish SRs in 7.62x51 are intended to shoot lower pressure CETME ammo. Having all of the information and understanding the context is kind of important too, wouldn't you agree?
This is your project and your $$, so you should probably build it to meet your expectations.
