If anyone really wants to play the 'my rifle is faster than yours' game, Alpha Muntions now have 7mm08 brass with their optimised case head design. Supposedly takes insane pressures.
I think the 7x57 will lose out due to the fact that no one really bothers to make exceptional brass for it. RWS maybe...
Lapua make 7x64 brass...
But some of the old CRF Mauser actions will probably let go long before the cases will, not saying anyone should ever go out of their way trying to burst a brass case of course!![]()
