I have had 257 Roberts and 25/06, great shooters for sure. The 257 Weatherby is the King of the 25 calibers I have killed some big critters with mine, it now has a 7.5 twist barrel and have got the heavies dialed in with it. The pics are almost everything I have taken with it with bullets from 87 Gr to 115's and none went more than 2 steps, the big elk took 2 to kill but he didn't take a step after the 1st shot. The longest was the Mulie at about 475 yards, the Elk was just over 375 yards, all I have shot with new barrel and the heavy 131 Gr is hogs and out to 700 yds its bang flop. The 257 Weatherby is the cleanest killing machine that I have.
