For truely open country mulies where shots can be easily 400 or 500 yards the .257 WBY mag wins hands down. THe 110 grain accubond should be starting out at about 3500 fps and will shoot much flatter than the 7mm Rem mag could ever dream of shooting.

You could easily sight a .257 Wby mag to be zero at 300 yards and rise less than 3.5 inches above the line of sight and then be only 3.5 inches low at 350 yards. At 400 yards hold on the hair line of the back. At 500 yards it will have only dropped about 20 inches. Clear out to 400 yards you never have to hold any higher than the animal.

The 7mm Rem mag is a great flat shooting cartridge but it can't equal the .257 Wby mag.

Of course if you don't plan on shooting to 400 yards and beyond then it won't make one bit of differance either way except that the .257 will kick less.
