Got a chronograph. My aging Nosler Reloading Guide Number Four says 46 max. is most accurate for their 160 Partition and about 2622 fps from 22" barrel, so maybe I will see 2650, more or less.

In reality, no animal will ever know if the 7mm 160 grain bullet that killed it had a MV of 2,550, 2,600, 2,650 or 2,700 fps.
Sure, it may make a difference in terms of trajectory, but if you want a flat shooting non-magnum 7mm for longer ranges, try a .280 or a .280 AI.
The great virtue of the 7x57 in my admittedly limited experience with it is light recoil, good accuracy and the ability to shoot 160-175 grain bullets at "reasonable" ranges.
