Description
Backcountry hunters have been asking for a rifle like this for years: real magnum reach in a package that doesn't punish you on the climb or at the trigger. The Weatherby 307 Alpine ST answers with a .300 Win Mag that tips the scales at just 6.3 pounds bare, built around the Model 307 action and a PEAK 44 Bastion carbon fiber stock that weighs a scant 24 ounces. The Bastion's vertical grip, ambidextrous palm swell, and generous thumb groove put your hand in the right spot naturally, and the 3D-Hex recoil pad takes some sting out of every shot. Dual sling studs up front give you room for a bipod and a sling at the same time.
What the Model 307 Action Brings to the Alpine ST
The 307 is a two-lug, fully cylindrical action sized to play nice with the huge aftermarket that already exists for that footprint, so stocks, triggers, rails, and mounts are easy to come by down the road. The spiral-fluted bolt strips down without tools for field cleaning, and an M16-style extractor keeps ejection positive when it counts. Weatherby backs every Model 307 with a sub-MOA guarantee, and the factory-installed TriggerTech Field trigger breaks clean with zero creep and adjusts externally down to 2.5 pounds.
A Barrel Built for the Long Poke
The spiral-fluted barrel measures 24 inches with the included Accubrake ST in place, wears a 1:10 twist that stabilizes heavy .30 caliber bullets, and is threaded 1/2-28 so you can swap the brake for a suppressor or thread protector. Graphite Black Cerakote covers the receiver, barrel, bolt, and brake, shrugging off weather and pack wear season after season.
Why the Alpine ST Earns a Spot in Your Truck
Between the two-position safety, three-round capacity, and that featherweight build, this is a purpose-driven elk and mule deer rifle that still shoots tight enough to be fun on steel. Top it with quality glass and it's ready for the high country.

Frequently Asked Questions
Is the barrel on the Weatherby 307 Alpine ST 22 or 24 inches?
Both numbers get thrown around, and here's why: the barrel itself measures 22 inches, and the factory-installed Accubrake ST adds roughly 2 more inches, bringing the total to 24 inches at the muzzle. If you remove the brake to run a suppressor, you're back to the 22-inch barrel. Plan your setup around that overall length.
Does the 307 Alpine ST come with an accuracy guarantee?
Yes. Weatherby guarantees all Model 307 rifles will print a 3-shot group of .99 inch or less at 100 yards from a cold barrel with Weatherby factory or premium ammunition, valid for two years from the verified purchase date for the original owner. That's a real sub-MOA promise from the factory, not just marketing talk.
Can I put a suppressor on the Alpine ST in .300 Win Mag?
You can. The muzzle is threaded 1/2-28, so once you spin off the Accubrake ST you can mount a can or adapter that matches that thread pitch. Just double check that your suppressor is rated for .300 Win Mag pressures before heading to the range.
How heavy is this rifle for backpack hunting?
Bare, the Alpine ST runs about 6.3 pounds, which is impressively light for a .300 Win Mag. The PEAK 44 Bastion carbon fiber stock weighs only 24 ounces, and the spiral-fluted barrel and skeletonized bolt handle trim more weight. Even with a scope and sling you should stay under 8 pounds, which your shoulders will appreciate on long climbs.
