Description
The Weatherby 307 MDT Carbon 25 Creedmoor is Weatherby’s Model 307 Alpine MDT Carbon chambered in 25 Creedmoor with a 22-inch barrel. It pairs Weatherby’s newest bolt action with a BSF carbon barrel and MDT’s ultralight HNT26 folding chassis, aimed at hunters who carry their rifle a long way and still want precision-rifle features. This listing is Weatherby SKU 3WAMC25CMR4B, UPC 747115462476.

Weatherby 307 MDT Carbon 25 Creedmoor Overview
The Model 307 is a 2-lug, fully cylindrical action built to fit the huge aftermarket of Remington 700-pattern stocks, triggers, rails and mounts. On the Alpine MDT Carbon, Weatherby teamed with MDT to drop that action into the HNT26 chassis, a carbon fiber vertical-grip system that weighs about 26 oz on its own. The buttstock folds, cutting more than 9 inches off the overall length for packing, travel or a smaller safe.
The receiver and Accubrake DST wear Carbon Grey Cerakote and the bolt and bolt knob are Graphite Black Cerakote, so the metal is protected against moisture and wear in the field.

BSF Carbon Fiber Barrel and Accubrake DST
The barrel on the Weatherby 307 MDT Carbon 25 Creedmoor comes from BSF, which wraps a match-grade stainless steel barrel in carbon while leaving air gaps between most of the carbon and the steel. That design keeps weight down and helps the barrel shed heat faster during strings of shots. The muzzle is threaded and fitted with Weatherby’s Accubrake DST, a side-ported, self-timing brake that sharply reduces muzzle rise and felt recoil. A timing nut lets you install or re-time it without a gunsmith.
Side-ported brakes are loud for the shooter and anyone beside them, so wear hearing protection and warn hunting partners or guides. If you remove the brake, use the correct thread protector.
Folding Chassis Rifle Features
Beyond the folding stock, the HNT26 has an adjustable cheekpiece and adjustable length of pull to fit different shooters and clothing layers. An integrated ARCA rail lets you clamp the rifle straight to a tripod or attach an ARCA bipod, and a Picatinny rail on the receiver accepts a wide range of scope mounts.

Weatherby 307 MDT Carbon 25 Creedmoor Trigger and Sub-MOA Guarantee
A TriggerTech trigger provides a zero-creep break and short overtravel, is externally adjustable down to 2.5 lb, and has a two-position safety. The three-piece bolt can be stripped without tools and uses an M16-style extractor for positive extraction. Every Model 307 carries Weatherby’s sub-MOA guarantee: a 3-shot group of .99 inch or less at 100 yards from a cold barrel with Weatherby factory or premium ammunition, within two years of verified purchase by the original owner.

Things to Consider Before Buying the Weatherby 307 MDT Carbon 25 Creedmoor
25 Creedmoor is a flat-shooting, efficient cartridge with high-BC bullets, but factory ammunition is far less common and usually more expensive than 6.5 Creedmoor or .308 Win. Before you buy, make sure you can source the loads you want, or plan to handload. A chassis stock feels different from a traditional hunting stock, and the vertical grip takes a little getting used to if you are coming from a sporter. Carbon barrels cost more than steel, and the value is in weight and heat management rather than extra accuracy. Check local hunting rules on cartridge minimums for big game.
