Weatherby 307 Alpine MDT Carbon 257 WBY Magnum Rifle – Superb 24 in

Description

The Weatherby 307 Alpine MDT Carbon 257 pairs the flattest shooting 25 calibre factory cartridge with the lightest folding chassis MDT builds. A 24 inch BSF carbon wrapped barrel wears an Accubrake DST, the Model 307 action sits in an MDT HNT26 carbon fiber and magnesium chassis, and the whole rifle weighs 6.7 pounds bare. Folded it measures 34.25 inches and extended it runs to 46.25 inches. The UPC is 747115456680. MAG5 Firearms lists it for open country hunters who pack in.

Cartridge Meets Chassis

257 Weatherby Magnum has been the flat shooting benchmark since 1944. A 100 grain bullet leaves a 24 inch barrel above 3300 feet per second, which produces a trajectory so flat that ranging errors cost you far less than they would with almost anything else. As a 257 weatherby magnum rifle this build gives you that reach without the weight penalty that traditionally came with a long barreled magnum.

The mdt hnt26 chassis is what separates this from a conventional stocked rifle. It is built from carbon fiber and magnesium rather than aluminum billet, so a folding chassis rifle lands under seven pounds instead of over ten. Comb height and length of pull both adjust, length of pull runs 12.5 to 13.5 inches, and the forend has an integrated ARCA rail for a tripod clamp or ARCA bipod. A Weatherby 307 Alpine MDT Carbon 257 folds for transport and the hinge locks tightly enough not to disturb zero.

Underneath is the Weatherby Model 307: a two lug bolt with an M16 style extractor, tool-less bolt disassembly for cleaning in camp, and a Remington 700 footprint so aftermarket bases, triggers and chassis fit. The trigger is a TriggerTech field unit adjustable from outside. The bsf carbon barrel is a steel liner in a carbon shell with a 1 in 10 twist, which is correct for the 100 to 120 grain bullets a Weatherby 307 Alpine MDT Carbon 257 runs best.

Honest Costs of This Combination

Barrel life is the real price of 257 Weatherby. A large powder charge behind a small bore erodes throats faster than a 25-06 or a 6.5 Creedmoor, and heavy practice schedules shorten it further. A Weatherby 307 Alpine MDT Carbon 257 is not a rifle to shoot fifty rounds an afternoon through. Sight it in, build a drop chart in two or three shot groups with cooling time, hunt with it, and budget for a rebarrel eventually if you use it hard.

Ammunition is proprietary and priced accordingly. Weatherby and a few other loaders make it, availability is reasonable but not universal, and it costs meaningfully more per round than common cartridges. Settle on one load, confirm it properly and buy enough of that lot number to cover two seasons. Many Weatherby 307 Alpine MDT Carbon 257 owners handload, and components are readily available if you go that route.

The Accubrake DST tames recoil on a 6.7 pound magnum, which is genuinely necessary at this weight, but it is loud. Hearing protection is mandatory at the bench and it is courteous to warn anyone standing beside you. A chassis is also colder and harder in the hand than a composite stock in late season, and the vertical grip on a Weatherby 307 Alpine MDT Carbon 257 takes adjustment if you have only shot sporter stocks.

Who Should Buy It

A Weatherby 307 Alpine MDT Carbon 257 makes sense for the hunter taking long shots at deer, antelope and sheep in open country, who packs a rifle rather than carries it slung, and who shoots off a tripod or a pack. The folding chassis and the flat trajectory serve exactly that shooter. Full factory specifications are published by Weatherby.

If ammunition cost and barrel life worry you, the 22 Creedmoor version of the same chassis rifle is far cheaper to shoot and recoils less, at the cost of terminal performance on larger game. If you want a conventional carbon stock instead of a chassis, look at the 307 Alpine CT in 257 Weatherby. Browse the rest of our rifles to compare.

Practical notes. Choose a bullet built for the impact velocity this cartridge generates, because a thin jacket at 3300 feet per second behaves badly on close shots. Pick a light scope with real elevation travel, buy rings that match the supplied rail, and pick up spare AICS pattern magazines. A Weatherby 307 Alpine MDT Carbon 257 rewards careful load selection more than it rewards accessories.
