The Weatherby 307 Alpine MDT Carbon is a bolt-action rifle chambered in .308 Win, built around a carbon composite MDT chassis stock that brings the rifle down to 6.5 lbs. That weight advantage matters when you're covering ground on a backcountry hunt.

Features 

The 20-inch threaded barrel (5/8x24) keeps the overall package manageable and allows suppressor or muzzle device attachment without additional gunsmithing. At a 1-in-10" twist, the barrel stabilizes standard .308 projectiles up through heavier match weights. The MDT chassis allows stock adjustments for length of pull and cheek height, which is useful when switching between shooting positions or mounting different optics. Bolt cycling is smooth and the 3+1 capacity is standard for this cartridge class. 
 
At 6.5 lbs., this is genuinely light for a precision bolt rifle with a chassis stock. Most comparable setups run 8-9 lbs. before optics.

Feedback on the Weatherby 307 Alpine MDT Carbon tends to cluster around a few consistent points.

Owners regularly comment on accuracy out of the box, with many reporting tight groups at distance without additional work. The carbon construction delivers on the weight claim. 6.5 lbs. is considered a genuine advantage by hunters who carry rifles all day. The MDT chassis gets positive marks for the adjustment range and for accepting common aftermarket accessories.

Recoil management under .308 is generally described as comfortable, even during extended range sessions.

On the critical side, the price draws scrutiny in comparison threads. Some buyers feel there are comparable-performing rifles at lower cost, though the weight and modularity combination is harder to match at that price point. Stock options and ergonomic fit are occasional topics. A few users have noted the chassis geometry doesn't suit every build or shooting style. Newer precision shooters sometimes find bolt-action technique requires more practice than expected compared to semi-automatic platforms.

Availability and wait times have been mentioned as frustrations at various points, suggesting demand runs ahead of inventory.
