The Weatherby 307 Alpine MDT Carbon is a bolt-action rifle built on the Model 307 action in a Rem 700 style footprint, chambered in 25 Weatherby RPM with a 22 inch carbon fiber and stainless steel barrel. The barrel is threaded, finished in carbon fiber, and fitted with an Accubrake. The rifle sits in an MDT chassis with an Arca rail forend and feeds from an AICS-compatible magazine holding 3+1 rounds.

Owners of the 307 Alpine MDT Carbon line generally like the fit and adjustability of the MDT chassis, the ability to set comb height and length of pull makes the rifle easier to get behind consistently than a fixed stock. The Model 307 action gets praise for a smooth trigger and reliable feeding from AICS-pattern magazines.

In the field, the carbon fiber barrel and chassis components keep the rifle manageable to carry despite the added bulk of a full aluminum chassis system. The Accubrake helps tame recoil from the RPM cartridge line, though a few shooters mention the brake is loud enough that hearing protection is a must at the range.

On value, buyers see the Alpine MDT Carbon as a step up in price from a standard Weatherby hunting rifle, justified by the chassis and carbon fiber components. Aftermarket support is strong since the MDT chassis and AICS magazine pattern are widely supported outside of Weatherby's own parts catalog.
