Weatherby Mark V Accumark .257 Wby Mag 26″ Barrel

Weatherby Mark V Accumark .257 Wby Mag 26″ Barrel

The Weatherby Mark V Accumark .257 Wby Mag 26″ barrel delivers a factory-built precision platform for serious hunters and long-range shooters. Built on the legendary Mark V action, this rifle pairs a fluted #3 contour 26-inch barrel with a hand-laid fiberglass Monte Carlo stock. The TriggerTech Field trigger and Accubrake ST muzzle brake come standard, and the receiver is drilled and tapped for optics. Chambered in .257 Weatherby Magnum, it offers flat trajectories and retained energy for elk, deer, and varmints alike.

Key Features

• Mark V Action with Fluted Forged Bolt – Why it matters: The nine-lug, 54-degree bolt lift provides smooth, reliable cycling and a short throw for rapid follow-up shots in the field.
• TriggerTech Field Trigger – Why it matters: Adjustable from 2.5 to 5 lbs with a crisp break and zero creep, this trigger gives you consistent accuracy shot after shot.
• Accubrake ST Muzzle Brake – Why it matters: Reduces felt recoil by up to 53% according to Weatherby, allowing faster target reacquisition and less fatigue during extended strings.
• Hand-Laid Fiberglass Monte Carlo Stock – Why it matters: Lightweight, weather-resistant, and free from grain inconsistencies, this stock maintains zero in wet or cold conditions and provides a stable cheek weld.
• Drilled and Tapped Receiver – Why it matters: Accepts standard Weaver-style bases and Picatinny rails for mounting optics without gunsmithing, simplifying setup for your preferred scope.

Who It’s For

This rifle is built for the precision hunter who demands flat-shooting ballistics from a lightweight package. Law enforcement snipers and competitive shooters will appreciate the factory accuracy and consistent trigger pull. The .257 Weatherby Magnum delivers high velocity and low drop, making it effective on game from pronghorn to mule deer out to 500 yards.

Pros and Cons

Pros: Factory-tuned accuracy with TriggerTech trigger; effective muzzle brake reduces recoil; lightweight fiberglass stock for carry; fluted bolt reduces weight and adds smooth operation.

Cons: The .257 Weatherby Magnum ammunition is less common than .308 or 6.5 Creedmoor, and barrel life is shorter due to high pressure—plan for 1,200–1,500 rounds before accuracy degrades.

FAQ

Does the rifle come with a scope or rings?

No. The receiver is drilled and tapped for standard bases. You’ll need to mount your own optics. We recommend a 3-15x or 4-16x scope for the .257 Wby Mag’s effective range.

What is the barrel twist rate?

The 26-inch #3 contour barrel has a 1:10 twist rate, optimized for 100- to 120-grain bullets commonly used in .257 Weatherby Magnum loads.

Is the Accubrake ST removable?

Yes. The brake is threaded onto the barrel and can be removed for cleaning or if you prefer a bare muzzle. A thread protector is not included—order separately.

How does the .257 Wby Mag compare to .300 Win Mag for long-range hunting?

The .257 Wby Mag has flatter trajectories and less recoil but carries less energy at extended ranges. For elk-sized game beyond 400 yards, .300 Win Mag has the edge. For deer and antelope under 500 yards, the .257 is superior.
