I just picked up a stainless Vanguard 257 Wby. Early tests with 100TSX's at 3600+ fps show it will pull it's weight.
But honestly, they all work. Even my 358 Norma with 225 TSX's at 2950 shoots flatter than most would believe. If the animal is a ways out, you need to know how far, and how to hold. Or compensate with turrets or a special reticle.
