I have owned or still own about 12 Mark V's and only one in a Weatherby caliber, a 240 WM. I like the 6 lug action and all have been excellent in the accuracy department. I understand the whole Mark V should be in a Weatherby cartridge but if you want a 6.5 creed, 270 win, 308, etc and like the Mark V, then buy it. It will not disaapoint
