Weatherby 307 Alpine MDT Carbon 300 Win Mag 22″
About this product
What is the Weatherby 307 Alpine MDT Carbon 300 Win Mag 22″? It is a lightweight, precision bolt-action rifle built for mountain hunting and long-range shooting, weighing just 6.60 lbs. This rifle combines Weatherby's Model 307 action with MDT's HNT26 carbon chassis system and a 22-inch BSF carbon barrel. The platform is designed for hunters who demand chassis-level adjustability without compromising on portability in challenging terrain.
What is the Weatherby 307 Alpine MDT Carbon used for?
The Alpine MDT Carbon is engineered for high-altitude hunting and precision shooting where every ounce matters. With its 6.60 lb weight and 36.5-inch folded length, it excels in mountain environments where packability outweighs pure benchrest accuracy. The .300 Winchester Magnum cartridge delivers ethical knockdown power on elk and moose out to 600 yards, while the adjustable chassis accommodates various shooting positions.
How does the Weatherby 307 Alpine MDT Carbon compare to the Stevens 334 Rifle?
The Alpine MDT Carbon outperforms the Stevens 334 in .308 Win in both weight reduction and long-range ballistics, but costs nearly three times more. Where the Stevens 334 weighs 7.25 lbs with its synthetic stock, the Alpine MDT Carbon achieves 6.60 lbs through premium carbon fiber construction. The .300 Win Mag generates 4,100 ft-lbs of muzzle energy compared to the .308's 2,800 ft-lbs, making it better suited for large game at extended ranges.
What does it weigh and what are the dimensions?
The rifle weighs 6.60 lbs (2.99 kg) with an overall length of 42 inches and folds down to 36.5 inches for transport. The 22-inch barrel features a 1:10 twist rate optimized for heavy projectiles from 180 to 220 grains. The MDT HNT26 chassis provides 1.5 inches of length-of-pull adjustment and 0.75 inches of comb height customization, accommodating shooters from 5'8" to 6'4".
Who is this NOT for?
This rifle is not suitable for beginners or budget-conscious shooters who won't utilize its specialized capabilities. The $3,449 price tag and .300 Win Mag's $3.50 per round ammunition cost make it prohibitively expensive for casual plinking. Recoil-sensitive shooters should consider the lighter-kicking Stevens 334 in .243 Win, as the Alpine's lightweight design transmits significant felt recoil even with the Accubrake DST.
What's in the box?
The rifle ships with one 3-round AICS pattern magazine and the factory-installed Accubrake DST muzzle device. Weatherby includes a limited lifetime warranty registration card but omits scope mounts or sling attachments that competitors often bundle. The entire package weighs 9.2 lbs in its shipping container, which measures 48x12x6 inches for UPS Ground compliance.
Is the Weatherby 307 Alpine MDT Carbon worth it at $3,449?
At $3,449, this rifle justifies its cost for serious backcountry hunters who demand maximum performance-to-weight ratio. The carbon fiber construction saves 1.5 lbs over traditional chassis rifles while maintaining sub-MOA accuracy with quality ammunition. For shooters who regularly pack rifles 10+ miles into alpine zones, the $1,000 premium over steel-barreled alternatives pays dividends in reduced fatigue and increased shot opportunities.

Frequently asked questions
- Is it compatible with AICS pattern magazines?
- Yes, the MDT HNT26 chassis accepts standard AICS pattern magazines. The rifle ships with one 3-round .300 Win Mag specific magazine, but aftermarket 5-round versions from MDT or Accuracy International function perfectly. Magazine changes require depressing the release lever located forward of the trigger guard.
- Does the Accubrake DST accept suppressors?
- No, the factory-installed Accubrake DST is a muzzle brake only and does not provide suppressor compatibility. The 22-inch barrel features 5/8x24 threads underneath the brake, requiring its removal and potential thread protector installation before mounting suppressors. Plan for 2-3 weeks ATF Form 4 approval if adding a .30 cal can like the Dead Air Nomad-L.
- How long does shipping take to FFL dealers?
- Ironclad Armory processes firearms shipments within 3 business days via UPS 2nd Day Air to your selected FFL. Transit time averages 2-4 business days depending on destination, with signature required upon delivery. We recommend confirming your FFL's hours before ordering to avoid storage fees.
- Can I return it if it doesn't fit my needs?
- Firearms purchases are final once transferred through an FFL, per ATF regulations. Ironclad Armory accepts returns only for manufacturing defects within 30 days, which undergo inspection by our gunsmith team. We recommend handling similar rifles like the <a href="/products/stevens-334-308win-20-3rd-black/">Stevens 334</a> at local dealers before purchasing specialty builds online.
