Is there a big difference between the Vanguard and the Mark V? I can see the diferences on paper, but is the Mark V worth double what the Vanguard costs. I am looking on picking up a 257 Weatherby mag in the vanguard with a wood stock and fit it with a Burris 4-14X40 scope, and a harris bi-pod. It all runs about 975$ still less than the Mark V does. Is the Mark V still a better buy?

I would appreciate any comments or opinions!!
Thanks
