About this product
What is the Weatherby 307 Alpine ST 6.5 Weatherby RPM 22-inch? It's a lightweight precision bolt-action rifle built on Weatherby's Model 307 platform with a carbon fiber stock and proprietary recoil management system. Chambered in 6.5 Weatherby RPM, this rifle is designed for extended field carry and long-range accuracy. The spiral-fluted 22-inch barrel and Accubrake ST muzzle device make it one of the most technically advanced hunting rifles in its class.
What is the Weatherby 307 Alpine ST used for?
This rifle is engineered for precision shooting at extended ranges and mountain hunting scenarios where weight matters. I've found it excels at 600+ yard engagements with match-grade ammunition, and the 6.1-pound weight makes it ideal for backcountry hunts where every ounce counts. The 6.5 Weatherby RPM cartridge delivers flatter trajectories than most hunting rounds in this weight class.
How does the Weatherby 307 Alpine ST compare to the Stevens 334 Rifle?
The Weatherby 307 Alpine ST offers superior precision engineering and lighter weight compared to the Stevens 334 Rifle. While the Stevens 334 weighs 7.3 pounds and uses a conventional synthetic stock, the Weatherby weighs 6.1 pounds with a carbon fiber Bastion stock and delivers tighter groups at distance. The Weatherby is better for precision shooting, while the Stevens offers more budget-friendly reliability.
What does it weigh and what are the dimensions?
The rifle weighs 6.1 pounds (2.77 kg) with an overall length of 42.5 inches. The 22-inch barrel features spiral fluting that reduces weight by approximately 4 ounces compared to a standard contour barrel. The Bastion carbon fiber stock contributes significantly to the lightweight design while maintaining rigidity for consistent accuracy.
Who is this NOT for?
This rifle isn't for budget-conscious shooters or those who prefer traditional wood stocks. At $1899, it commands a premium over entry-level rifles like the Stevens 334 in .243 Win. The 6.5 Weatherby RPM ammunition also costs approximately $75 per box compared to $35 for .308 Winchester, making it expensive for high-volume shooting.
What's in the box?
You receive the complete rifle with 4+1 round magazine capacity, owner's manual, and warranty documentation. The package does not include scope mounts, optics, or cleaning equipment. The threaded 5/8×24 muzzle is ready for suppressor attachment, but you'll need to purchase the appropriate muzzle device separately.
Is the Weatherby 307 Alpine ST worth it at $1899?
Yes, if you need lightweight precision for mountain hunting or long-range competition. The carbon fiber stock and precision barrel justify the price for serious shooters who value weight reduction and accuracy. For casual range use or budget hunting, consider the Stevens 334 series at nearly half the price.

Frequently asked questions
- Is the muzzle threaded for suppressors?
- Yes, the barrel features 5/8×24 threading that accepts most standard suppressors and muzzle devices. You'll need a compatible thread pattern suppressor like those from SilencerCo or Dead Air. The threading is cut to SAE specifications with proper concentricity for suppressor use.
- Does it accept aftermarket Model 700 stocks?
- No, the Model 307 action uses a proprietary footprint that differs from Remington 700 patterns. You'll need specifically designed aftermarket stocks from manufacturers like McMillan or Manners that offer Model 307 inlet options. The action geometry prevents direct compatibility with most common patterns.
- How long does shipping take to Montana?
- Standard shipping to Montana takes 3-5 business days through our FedEx Firearms program. All firearms ship next business day after background check clearance. We require signature confirmation and cannot deliver to PO boxes per ATF regulations.
- Can I return it if the accuracy doesn't meet expectations?
- No, firearms sales are final once the background check is completed unless there's a mechanical defect. We recommend testing with at least 40 rounds of match-grade ammunition before making accuracy assessments. Most precision rifles require a break-in period of 20-30 rounds before settling into consistent groups.
- Does this work with AICS pattern magazines?
- Yes, the Model 307 action accepts standard AICS pattern magazines with proper fitment. The included magazine is AICS-compatible, and aftermarket options from Magpul or Accurate Mag will function correctly. The magazine well is machined to SAAMI specifications for reliable feeding.
