The Weatherby 307 Alpine MDT 7mm Backcountry rifle is a chassis-based hunting rifle on the tool-less-takedown Model 307 action (brand part no. 3WAMH7MMBR2B). It sits in MDT’s 26-ounce HNT26 chassis with v-block bedding, an adjustable cheekpiece, adjustable length of pull and a foldable buttstock. It is chambered in 7mm Backcountry with a 20-inch barrel, a 3+1 magazine capacity and a 1:8 twist, and the barrel is threaded 1/2-28 and fitted with the Accubrake muzzle brake. The spiral-fluted barrel sheds weight, adds rigidity and helps the barrel cool. Weatherby builds it at its Sheridan, Wyoming headquarters, and Weatherby backs every Model 307 with a sub-MOA accuracy guarantee when it is fed Weatherby factory or premium ammunition.
