The Weatherby NorthMark is a special edition Mark V, released in limited numbers specifically for the Canadian market. It carries all the standard features of the Mark V Ultralight, as well as a little extra engraving on the floorplate.

These particular rifles are all chambered in the new 6.5-300 Weatherby, the latest of the recent batch of high velocity .264 diameter cartridges. Capable of pushing a 140 grain bullet at speeds in excess of 3300 FPS, the 6.5-300 WBY is possibly the flattest shooting medium bore factory cartridge currently available.
