The Weatherby 307 Alpine ST Rifle in 25 Creedmoor with a 22-inch barrel is a precision bolt-action system built for shooters who demand low weight without compromising accuracy. This rifle pairs Weatherby’s Model 307 action with a Peak 44 Bastion carbon-fiber stock, a spiral-fluted barrel, and the integrated Accubrake ST muzzle brake. It is designed for disciplined field use, modular upgrades, and consistent terminal performance.

Key Features
- Peak 44 Bastion Carbon-Fiber Stock — Reduces overall weight to 6.0 lbs while maintaining rigidity for consistent shot-to-shot repeatability in field conditions.
- Spiral-Fluted Barrel with Accubrake ST — The fluting dissipates heat faster and reduces barrel whip; the integrated brake cuts recoil by up to 30%, allowing faster follow-up shots without disturbing sight picture.
- Modular Model 307 Action — Drilled and tapped for optics, and compatible with standard AR-style grips and aftermarket triggers, so you can build a custom platform without gunsmithing.
- 25 Creedmoor Chambering — Balances flat trajectory and retained energy at extended ranges (500-800 yards) with less recoil than .260 Rem or 6.5 Creedmoor, making it ideal for precision hunting and tactical shooting.
Who It’s For
This rifle is for the serious shooter who carries a rifle into backcountry terrain and requires a lightweight, modular platform that holds sub-MOA accuracy. It suits law enforcement marksmen, military precision shooters, and competitive hunters who prioritize weight savings and reliability over cost.
Pros/Cons
- Pros: Sub-6.5 lb ready-to-hunt weight, spiral-fluted barrel aids cooling, Accubrake ST effectively reduces recoil, fully modular stock and trigger system, 25 Creedmoor offers excellent ballistic coefficients.
- Cons: The carbon-fiber stock can feel slick in wet conditions without additional grip tape; aftermarket support for 25 Creedmoor ammunition is less widespread than 6.5 Creedmoor, limiting off-the-shelf load variety.

FAQ
What is the weight of the Weatherby 307 Alpine ST?
Per manufacturer specs, the rifle weighs 6.0 lbs unloaded without optics. The carbon-fiber stock and spiral-fluted barrel contribute to this low weight.
Is the barrel threaded for a suppressor?
The barrel is threaded 5/8×24 and includes the Accubrake ST muzzle brake. The brake can be removed to attach a suppressor, provided the suppressor is rated for 25 Creedmoor pressures.
What type of scope base does it require?
The receiver is drilled and tapped for #8-40 screws and accepts standard Picatinny rails (0 MOA or 20 MOA) compatible with Weatherby Model 307 actions. We recommend a 20 MOA rail for long-range shooting.
What is the effective range of the 25 Creedmoor chambering?
With high-BC bullets like the 131 gr Blackjack or 135 gr Berger, the 25 Creedmoor maintains supersonic velocity past 1,200 yards and delivers sub-MOA accuracy to 800 yards under field conditions.
