I used to run 2,940fps with 140gr. Noslers in both of my standard 7mm Mausers in a BRNO (24") & Ruger #1(22") - another good round and at least the equal of the .270.
The .280 should add another 100fps to the 7 Mauser - perhaps 150fps.
140g at 2940?
Admittedly my experience with the 7x57 is with the 7x57R but I believe your loading a wee touch on the hot side there my friend. Funnily enough though O'Conners coments about the .270 pertained to similarly hot loads - 130g at 3200fps which is now the realm of WSM factory fodder.
Does the 7x57 equal and surpass the .270? bit hard to tell if you compare hotrod handloads to current factory rounds and vice versa. What leaves me scratching my head is the last fellow I heard espouse this position doesn't own a chrony...
