Weatherby Mark V Backcountry Guide 6.5×300 26″

Description

The Weatherby Mark V Backcountry Guide in 6.5×300 Weatherby Magnum with a 26-inch barrel is a purpose-built bolt-action rifle that delivers magnum terminal performance in a lightweight, pack-ready platform. Designed for the hunter who demands both reach and carry comfort, this rifle pairs a BSF carbon-fiber barrel with a Peak 44 Blacktooth stock and a 3DHex recoil pad to manage the substantial recoil of the 6.5×300 Weatherby cartridge. The result is a sub-7-pound rifle that shoots flat, hits hard, and carries like a dream.

Key Features

• BSF Carbon-Fiber Barrel — reduces overall weight by nearly 30% compared to a steel barrel of equal length, while maintaining the stiffness needed for sub-MOA accuracy with the 6.5×300 Weatherby cartridge.
• Peak 44 Blacktooth Stock with 3DHex Recoil Pad — this carbon-fiber stock absorbs felt recoil from the magnum cartridge far better than traditional synthetic stocks, allowing faster follow-up shots without flinching.
• Machined Titanium Accubrake ST — the factory-installed, threaded titanium muzzle brake reduces recoil by up to 53% according to Weatherby’s internal testing, making the 6.5×300 manageable even for lighter-framed shooters.
• Adjustable TriggerTech Trigger — a crisp, single-stage trigger that can be set from 2.5 to 5.5 lbs without tools, giving you the precision needed for long-range shots on game.
• Spartan Precision Gunsmithing Kit — includes a recoil lug and action screws that allow you to mount a Spartan bipod or other accessories directly to the stock without aftermarket modifications.

Who It’s For

This rifle is for the backcountry hunter who needs a magnum cartridge for elk, moose, or mountain goat but refuses to carry a 9-pound rifle. It’s also for the collector who appreciates Weatherby’s heritage of high-velocity cartridges and the modern engineering that makes them practical in a lightweight carbon-fiber package.

Pros & Cons

• Pros: Extremely lightweight for a magnum rifle (6.9 lbs); excellent recoil management via the Accubrake and 3DHex pad; carbon-fiber barrel retains accuracy under sustained fire; adjustable TriggerTech trigger enhances precision.
• Cons: The 6.5×300 Weatherby cartridge is a proprietary caliber, so ammunition is less common and more expensive than 6.5 Creedmoor or .300 Win Mag; the carbon-fiber stock, while light, can be slippery in wet conditions without added grip tape.

Frequently Asked Questions

What is the effective range of the Weatherby Mark V Backcountry Guide in 6.5×300?

The 6.5×300 Weatherby Magnum is a flat-shooting cartridge; with a 140-grain bullet at 3,200 fps muzzle velocity, you can expect a point-blank range of about 350 yards and effective hunting range out to 700 yards with proper bullet selection.

Does the rifle come with a scope or mounts?

No, the rifle is sold without optics or mounts. The receiver is drilled and tapped for Weatherby’s proprietary scope base pattern (No. 2), and we recommend a quality 3-15x or 4-16x scope for this magnum.

Is the muzzle brake removable?

Yes, the titanium Accubrake ST is threaded onto the 5/8×24 muzzle and can be removed with a wrench. The barrel is threaded for direct attachment of a suppressor or other muzzle device.

What is the twist rate on the 26-inch barrel?

The barrel has a 1:8 twist rate, stabilizing bullets from 130 to 160 grains — perfect for the long, high-BC projectiles used in the 6.5×300 Weatherby cartridge.
