A couple of years ago I bought several brands of 7x57 and 7mm-08 factory ammo at a local store and shot them in a pair of rifles that had the same barrel length. Brands were Federal, Winchester and Remington. The average difference in muzzle velocity was about 100 fps, and less than that in some loadings. I doubt anybody would ever be able to tell the difference in the field.
Well, except for the fact that Federal still offers a 175-grain load in the 7x57.
