Weatherby 307 Range SF 6.5 Creedmoor 20″ Threaded Tungsten

The Weatherby 307 Range SF 6.5 Creedmoor 20″ Threaded Tungsten is a production bolt-action rifle engineered for consistent sub-MOA accuracy from the factory. Built on the Model 307 platform, this rifle integrates a 20-inch heavy Sendero barrel with an Accubrake muzzle device, a TriggerTech Field trigger, and an adjustable synthetic stock. It ships with a Magpul detachable magazine and is finished in Tungsten Cerakote for corrosion resistance. This is a precision-oriented tool for shooters who demand repeatable performance at range without custom gunsmithing.

Key Features

• 20″ Heavy Sendero Threaded Barrel — WHY IT MATTERS: The Sendero contour adds stiffness for sustained fire without excessive weight, and the 5/8×24 threading accepts standard muzzle devices like the included Accubrake or a suppressor.
• TriggerTech Field Trigger — WHY IT MATTERS: Externally adjustable from 2.5 to 5 lbs with zero creep and a crisp break, reducing shooter-induced error during precision strings.
• Adjustable Stock with Cheekpiece and LOP — WHY IT MATTERS: The comb height adjusts via a tool-free wheel, and length of pull changes with included spacers, allowing a custom fit for body armor or varied shooting positions.
• M16-Style Extractor — WHY IT MATTERS: Positive case extraction under all conditions, including hot chambers or fouled ammunition, reducing malfunctions during high-round-count drills.
• Magpul AICS-Pattern Magazine — WHY IT MATTERS: Uses widely available AICS-pattern magazines, offering reliable feeding and easy reloads in a competitive or field environment.

Who It’s For

This rifle is built for law enforcement precision marksmen, competitive shooters in PRS or NRL Hunter divisions, and serious civilian shooters who need a production rig that holds 0.5–0.75 MOA out of the box. It also suits hunters who want a lightweight, adjustable platform for long-range shots in open country.

Pros and Cons

• Pro: Factory-sub-MOA guarantee backed by Weatherby’s test target.
• Pro: TriggerTech trigger reduces pull weight variability compared to standard two-stage triggers. According to Weatherby specs, the trigger is externally adjustable without removing the action from the stock.
• Pro: Tungsten Cerakote finish resists salt spray and abrasion better than blued steel.
• Con: Stock is not fully adjustable for cast-on/cast-off; left-handed shooters may need an aftermarket chassis for perfect alignment.
• Con: Barrel is 20 inches, which limits muzzle velocity by approximately 50–75 fps compared to a 24-inch barrel in 6.5 Creedmoor.

FAQ

Does the Weatherby 307 Range SF come with a scope rail or rings?

No, the rifle does not include a scope rail or rings. The receiver is drilled and tapped for a standard Picatinny rail (20 MOA recommended for long-range use). You will need to purchase a rail and rings separately.

What is the barrel twist rate on this model?

The 20-inch Sendero barrel has a 1:8 twist rate, optimized for stabilizing 120- to 147-grain 6.5 Creedmoor projectiles. This covers most match and hunting loads.

Can I use this rifle for hunting?

Yes, the 6.5 Creedmoor is effective for medium game like deer and antelope out to 500 yards. The 20-inch barrel keeps weight down, and the adjustable stock aids in quick shouldering. However, the heavy Sendero contour adds weight compared to a sporter barrel.

Is the Accubrake removable for suppressor use?

Yes, the Accubrake is threaded onto the 5/8×24 muzzle and can be removed with a wrench. The barrel is threaded to accept standard direct-thread suppressors or other muzzle devices.
