The Weatherby 307 Range SF 300 Win Mag 22in Threaded RH is a factory-built precision rig that skips the custom wait time. It’s a no-nonsense long-range tool chambered in .300 Winchester Magnum, built on the Model 307 two-lug action with a heavy 22-inch threaded barrel and factory Accubrake. This is a production rifle that handles like a semi-custom build—right out of the box.

Key Features
- Model 307 Two-Lug Action: This is a controlled-round-feed action with a 90-degree bolt throw. Why it matters: it feeds .300 Win Mag rounds reliably from the mag, even under rapid fire in a match.
- Heavy 22-Inch Threaded Barrel with Accubrake: The barrel is 5/8-24 threaded and comes with Weatherby’s Accubrake muzzle brake. Why it matters: it cuts recoil by about 50%, letting you spot your own impacts at distance without losing the sight picture.
- TriggerTech Field Trigger: A drop-in trigger with a 2.5–5 lb adjustable pull, zero creep, and a crisp break. Why it matters: predictable trigger control is the difference between a hit and a miss on a 1,000-yard steel plate.
- Adjustable Synthetic Stock: Cheekpiece height and length of pull are tool-less adjustable. Why it matters: you can dial in a perfect cheek weld for any optic setup, from a low-power variable to a high-magnification scope.
- Magpul Detachable Magazine: Uses AICS-pattern 3-round magazine. Why it matters: fast reloads and easy unloading for matches, plus aftermarket mag options from Magpul and Accurate-Mag.
Who It’s For
This rifle is built for the PRS/NRL shooter who wants a .300 Win Mag for heavy-class competition, or the hunter who needs a flat-shooting magnum for long-range elk or mule deer. If you’re a reloader who pushes 210–220 grain Berger hybrids at 2,800+ fps, this is your platform. It’s also for the precision enthusiast who wants a ready-to-run rifle without sending it to a gunsmith for a barrel swap.
Pros & Cons
- Pro: Accubrake works—recoil feels like a .308 Win, not a .300 Mag.
- Pro: TriggerTech trigger is match-grade out of the box.
- Pro: Stock adjustments are tool-less and repeatable.
- Con: The factory stock lacks an ARCA rail or M-Lok slots for heavy bipod mounts. You’ll need an aftermarket chassis if you run a full competition setup.

FAQ
Does the Weatherby 307 Range SF come with a scope base?
Yes. The receiver is drilled and tapped for Remington 700 short-action bases. You’ll need to buy rings and a base separately if you don’t have them.
Is the Accubrake removable?
Yes. It’s threaded onto the 5/8-24 muzzle and can be removed with a wrench. If you remove it, the barrel is still threaded for a suppressor or other brake.
What is the twist rate on the .300 Win Mag barrel?
Per Weatherby specs, the twist rate is 1:10 inches. This stabilizes the most common .30 caliber match bullets from 168 grain to 220 grain.
Can I use standard Remington 700 triggers?
Yes. The Model 307 action uses Remington 700 footprint triggers. You can drop in a Timney, Jewell, or TriggerTech aftermarket trigger without modifications.
