Description
The Weatherby 307 Alpine ST .300 Weatherby Magnum 24″ is a purpose-built long-range mountain rifle that sheds weight without sacrificing precision. Built on the two-lug Model 307 action, it combines a spiral-fluted, 24-inch barrel with the Weatherby Accubrake ST to manage recoil while keeping the total mass low. The PEAK 44 Bastion carbon-fiber stock and proprietary 3D-Hex recoil pad make this package ready for high-country stalks and extended range sessions alike.

Key Features
- Spiral-Fluted Barrel with Accubrake ST — Reduces barrel weight by 12% while the integrated muzzle brake cuts felt recoil by up to 30%, letting you stay on target for follow-up shots.
- PEAK 44 Bastion Carbon-Fiber Stock — Keeps the rifle under 7 lbs total, and the 3D-Hex recoil pad soaks up the .300 Wby Mag’s punch without adding bulk.
- Model 307 Two-Lug Action — Fully cylindrical design accepts aftermarket triggers, rails, and stocks from brands like Timney and Geissele, so you can upgrade without a gunsmith.
- 24-Inch Barrel Length — Balances portability with velocity; the .300 Weatherby Magnum still pushes 180-grain bullets past 3,100 fps out of this tube.
- Matte Cerakote Finish — Resists corrosion and glare in alpine environments, proven in field tests from the Rockies to the Cascades.
Who It’s For
This rifle is built for the backcountry hunter who hikes miles to a glassing knob and needs one accurate shot on a bull elk at 400 yards. It also suits the precision shooter who wants a lightweight platform for steel out to 1,000 yards without hauling a 12-lb bench gun. If you carry a rifle all day and expect sub-MOA performance, the Alpine ST fits.
Pros & Cons
- Pro: Sub-7-lb weight with full-size .300 Magnum power — rare in production rifles.
- Pro: Accubrake ST makes the .300 Wby Mag manageable for rapid follow-ups.
- Pro: Aftermarket-friendly action lets you swap triggers and stocks easily.
- Con: The Accubrake ST is loud for the shooter and anyone nearby — always wear ear pro, even in the field.

FAQ
Is the Weatherby 307 Alpine ST accurate out of the box?
Yes. According to Weatherby specs, the Alpine ST is guaranteed to shoot sub-MOA groups at 100 yards with match-grade ammunition. The spiral-fluted barrel and carbon-fiber stock work together to minimize harmonics and maintain consistency.
Can I mount a suppressor on this rifle?
The barrel is threaded 5/8×24 and comes with a thread protector. You can remove the Accubrake ST and attach a suppressor, but note the brake is integral to the barrel profile — you’ll need a direct-thread or QD mount that fits the same thread pitch.
What is the magazine capacity?
The .300 Weatherby Magnum version comes with a detachable box magazine holding 3 rounds. A 5-round magazine is available separately from Weatherby.
Does the stock have adjustable length of pull?
No. The PEAK 44 Bastion carbon-fiber stock has a fixed length of pull at 13.5 inches. You can add or remove spacers via the included buttpad system, but it’s not tool-less.
How does the Accubrake ST affect recoil?
Per Weatherby’s testing, the Accubrake ST reduces felt recoil by 30% compared to an unbraked barrel. In a 6.5-lb .300 Wby Mag, that’s the difference between a sharp shove and a firm push — manageable for extended range sessions.
