Saami chamber psi is 51,000 for 7x57.
Remington 700 is clearly capable of handling 65,000, as in some Weatherby chamberings.
Brass is just a gasket, some might hold better than others. Necking down 8x57 Lapua could produce the best brass in the chambering.
Nothing says you can or should load it to the wall, but at equal pressures the old 7 is as capable as anything above ,below or beside it.
It can outclass a 7mm08 & comparing it to a 284 Win. or 7mm06 is fruitless. The later 2 can outpace, but only by a slim margin. Like picking the pepper out of fly chit.
