The Weatherby 307 Alpine MDT Carbon .300 PRC rifle is a chassis-based hunting rifle with a BSF carbon fiber barrel on the tool-less-takedown Model 307 action (brand part no. 3WAMC300PR4B). 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 .300 PRC with a 22-inch barrel, a 5+1 magazine capacity and a 1:10 twist, and the barrel is threaded 5/8-24 and fitted with the Accubrake DST muzzle brake. A BSF carbon fiber barrel sleeves a match-grade 416R stainless steel barrel under tension, which Weatherby says keeps the rifling straighter as the barrel heats. 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.
