The Weatherby is a fine rifle, I have long lust after a Mark V .257. If it's truly what you want far be it from me to tell you otherwise.
However, with a couple grand on the line I send my money to Kirby Allen everytime. I have spoken with him about building me a Lightweight on a Borden action. Half the cost of a Jarrett and It will flat embarass a just about everything else accuracy wise. Gunwerks? well, their well promoted.
