The Weatherby 307 Alpine MDT .257 WBY 28″ Folding Chassis is a lightweight, precision bolt action rifle built for backcountry hunters and long-range shooters. It pairs Weatherby’s proven Model 307 action with an MDT HNT26 magnesium/carbon fiber folding chassis, chambered in the fast .257 Weatherby Magnum. This rig weighs just over 6 pounds, making it easy to carry all day without sacrificing accuracy.

Key Features
- MDT HNT26 Folding Chassis — Why it matters: This magnesium/carbon fiber stock cuts weight without stiffness, letting you fold the rifle down to 27 inches for easy packing in a backpack or case.
- Spiral-Fluted Threaded Barrel with AccuBrake — Why it matters: The fluting reduces barrel weight and helps cool faster, while the included AccuBrake cuts recoil so you stay on target for quick follow-up shots.
- TriggerTech Trigger — Why it matters: It gives a crisp, consistent 2.5–3 lb pull with zero creep, helping you shoot tighter groups right out of the box.
- Adjustable Length of Pull and Cheek Riser — Why it matters: You can dial in the fit for any shooter or shooting position, from prone to barricade, without tools.
- .257 Weatherby Magnum Chambering — Why it matters: This cartridge pushes a 100-grain bullet at over 3,500 fps, delivering flat trajectories and hard-hitting energy on deer, antelope, and varmints.
Who It’s For
This rifle is for the hunter who wants one rig that can do it all: spot-and-stalk in the mountains, precision shooting at the range, and packing into tight spots like a truck cab or plane. It also suits new shooters who want a lightweight, adjustable platform that grows with their skills.
Pros and Cons
- Pro: At 6.2 pounds, it’s one of the lightest production folding chassis rifles available in .257 WBY.
- Pro: The folding stock locks up solid and returns to zero every time.
- Con: The .257 Weatherby Magnum has more recoil than a .243 or 6.5 Creedmoor, so new shooters should practice with reduced loads first.
