Weatherby set out to produce the best backcountry rifle and cartridge combination ever, it was a project they did not take lightly. They pride themselves in ballistic superiority.

Instead, their team was able to break the 5-pound mark while delivering magnum performance in a firearm that doesn’t demand custom rifle pricing. Additionally, the combination of the stock design, brand new muzzle break, and proprietary patent-pending 3DHEX recoil reducer make it enjoyable to shoot. After years of innovation and development, the Mark V Backcountry Ti and 300 Weatherby Magnum combination achieves the weight savings, ballistic performance, and price that cannot be found in a production rifle anywhere else.
