The Weatherby 307 Alpine MDT Carbon 6.5 RPM bolt-action, 22in is a purpose-built precision rifle that merges Weatherby’s new 307 action with an MDT HNT26 carbon fiber chassis and a 22-inch BSF carbon fiber barrel. Chambered in 6.5 Weatherby RPM, this rig delivers a sub-7-pound package for backcountry hunters and tactical shooters who demand accuracy without the weight penalty.

Key Features
- BSF Carbon Fiber Barrel (22-inch): Why it matters — reduces weight by roughly 40% over a steel barrel of the same length while maintaining harmonic stability for sub-MOA accuracy.
- MDT HNT26 Chassis: Why it matters — an aluminum backbone wrapped in carbon fiber gives you a rigid, adjustable platform that shaves ounces and allows for LOP and cheek riser tuning without tools.
- Threaded Muzzle (5/8×24): Why it matters — accepts standard direct-thread suppressors or muzzle brakes, keeping the overall length manageable for suppressed field use.
- Three-Lug, 60-Degree Bolt Lift: Why it matters — provides ample scope clearance and fast cycling, critical for follow-up shots on moving targets.
- AICS Magazine Compatibility: Why it matters — uses widely available, affordable magazines, and the 3+1 capacity keeps the profile low for prone or pack carry.
Who It’s For
This rifle is built for precision-minded shooters who operate in rugged terrain — backcountry hunters, reconnaissance marksmen, and tactical competitors who need a lightweight rig that holds its zero through elevation changes and hard use.
Pros and Cons
- Pro: 6.6 lb unloaded weight with a full-length 22-inch barrel — rare in a magnum-chambered precision rifle.
- Pro: 6.5 Weatherby RPM offers a flatter trajectory and higher retained energy than 6.5 Creedmoor out to 600+ yards.
- Con: Aftermarket support for the 307 action is still limited compared to Remington 700 or Tikka platforms; you’ll rely on Weatherby-specific parts for now.

FAQ
What is the barrel twist rate on the Weatherby 307 Alpine MDT Carbon?
The 22-inch BSF carbon fiber barrel has a 1:7.5 twist rate, optimized for stabilizing heavy 6.5mm projectiles like the 147-grain ELD-M and 140-grain Berger hybrids.
Does this rifle come with a scope base?
Yes, the receiver is drilled and tapped for a Picatinny rail (not included). Weatherby recommends using a 20 MOA rail to maximize elevation travel for long-range shooting.
Can I use a standard AICS magazine with this rifle?
Yes, the MDT HNT26 chassis accepts all AICS-pattern short-action magazines. The rifle ships with one 3-round magazine.
Is the 6.5 Weatherby RPM ammo easy to find?
Factory ammunition from Weatherby and select independent loaders is available online, though it’s less common than 6.5 Creedmoor. Reloading components (brass, dies) are widely available. Per Weatherby, the RPM case offers 200-300 fps over 6.5 Creedmoor with similar recoil.
What is the overall length of this rifle?
Overall length is 44.25 inches. With the 22-inch barrel and 5/8×24 threaded muzzle, it fits standard rifle cases and gun safes.
