Description
The Weatherby 307 Alpine ST Rifle 7mm PRC is built for hunters who need a lightweight, accurate rifle that handles tough mountain terrain without weighing you down. Chambered in the hard-hitting 7mm PRC, this bolt-action rifle uses Weatherby’s Model 307 platform—a modular design that accepts aftermarket stocks, triggers, and rails. The spiral-fluted, threaded barrel comes with Weatherby’s Accubrake ST muzzle device to cut recoil, and the PEAK 44 Bastion carbon-fiber stock keeps the whole rig under 7 pounds. If you want a factory rifle that shoots like a custom build, this is it.

Key Features
- Spiral-fluted, threaded barrel with Accubrake ST — WHY IT MATTERS: The fluting sheds weight and helps the barrel cool faster between shots, while the Accubrake ST reduces felt recoil by up to 50%, so you stay on target for quick follow-ups.
- PEAK 44 Bastion carbon-fiber stock — WHY IT MATTERS: This stock is rigid enough for consistent accuracy but light enough to carry all day. The textured grip panels give you a solid hold in wet or cold conditions.
- Model 307 bolt-action platform — WHY IT MATTERS: The 307 action is designed for modularity—you can swap stocks, triggers, and bottom metal without a gunsmith. That means you can upgrade the rifle as your needs change.
- 7mm PRC chambering — WHY IT MATTERS: The 7mm PRC pushes a 175-grain bullet at over 2,950 fps, giving you flat trajectories and retained energy past 1,000 yards. It’s a legitimate long-range hunting cartridge that doesn’t beat you up.
- Threaded barrel (5/8-24) with thread protector — WHY IT MATTERS: You can mount a suppressor or muzzle brake right out of the box without extra work. The thread protector keeps the muzzle clean when you’re not running a can.
Who It’s For
This rifle is for the backcountry hunter who wants one gun that can do it all—spot-and-stalk elk in the Rockies, sit a stand for whitetail in the Midwest, or shoot steel at the range. It’s also a great fit for the shooter who likes to customize: the modular design means you can swap to a chassis system or a different trigger later. New gun owners will appreciate the low recoil and the factory-tuned accuracy; experienced shooters will like the modern cartridge and lightweight build.
Pros / Cons
- Pros: Very light (under 7 lbs), modular platform, effective muzzle brake, accurate out of the box, modern cartridge with great ballistics.
- Cons: The carbon-fiber stock is lightweight but can feel a bit flexy under heavy bipod pressure. Also, 7mm PRC ammo is still not as common as 6.5 Creedmoor or .308 Win, so you’ll want to stock up online or at a shop that carries it.

FAQ
What is the barrel twist rate on the Weatherby 307 Alpine ST?
The barrel has a 1:8 twist rate, which stabilizes the heavy 175-grain bullets common in 7mm PRC loads. That twist also handles lighter 140-grain bullets well for varmint hunting.
Does the Weatherby 307 Alpine ST come with a scope base?
Yes, the rifle includes a Picatinny rail (20 MOA) pre-installed from the factory. You can mount most standard rings or one-piece mounts directly.
Can I use a suppressor on this rifle?
Yes. The barrel is threaded 5/8-24 and comes with a thread protector. Just remove the Accubrake ST and screw on your suppressor. The barrel is long enough (22″) to keep most suppressors from interfering with the stock.
Is the 7mm PRC ammo hard to find?
It’s more available than it was two years ago. Major brands like Hornady, Federal, and Nosler load it, and online retailers usually have it in stock. You’ll see it alongside 6.5 PRC and .300 PRC in most shops now.
