Weatherby Alpine ST 6.5×300 Weatherby Mag 26″
About this product
What is the Weatherby Alpine ST 6.5×300 Weatherby Mag 26″? It's a purpose-built mountain rifle combining Weatherby's proprietary 6.5×300 Weatherby Magnum cartridge with a lightweight carbon-fiber and fluted barrel platform, engineered for extreme-distance accuracy and reduced carry weight. Built on Weatherby's modular Model 307 bolt-action, this rifle represents a modern interpretation of high-performance, low-drag hunting tools. Its design directly addresses the needs of shooters who must balance terminal ballistics at extended ranges with the physical demands of backcountry hunting.
What is the Weatherby Alpine ST used for?
The Alpine ST is engineered for low-weight, high-energy hunting applications where shots regularly exceed 400 yards. Its configuration—a 26-inch fluted barrel and 9.35-lb weight—is optimized for stability at those distances without becoming a burden during alpine approaches. The cartridge reliably delivers over 3,300 ft-lbs of muzzle energy, making it suitable for elk, moose, and other large game at ranges where standard magnums run out of steam. This isn't a casual timber rifle; it's a system for open-country specialists.
How does the Weatherby Alpine ST compare to the Stevens 334 .243 Win?
The Alpine ST is a specialized, high-energy platform, while the Stevens 334 .243 Win is a general-purpose, low-recoil option for lighter game. The Stevens fires a cartridge that produces roughly 1,700 ft-lbs of muzzle energy, less than half the Alpine ST's output, and its 20-inch barrel is better for maneuverability than extended ballistics. The Alpine ST is superior for ethical, long-range shots on larger animals; the Stevens is better for deer at moderate distances and shooters sensitive to recoil.
What does it weigh and what are the dimensions?
The rifle weighs 9.35 lbs, measures 46 inches in overall length, and features a 26-inch barrel with a 1-in-8-inch twist rate. This weight includes the factory-mounted PEAK 44 Bastion carbon-fiber stock and a 3+1 round detachable magazine, but not optics. The 5/8×24 threaded muzzle adds 1.5 inches of length with a typical suppressor mount or muzzle device. Compared to a traditional walnut-stocked magnum rifle, this configuration saves approximately 1.8 to 2.5 lbs in carry weight, a critical difference over miles of elevation gain.
Who is this NOT for?
This rifle is not for budget-conscious shooters, those new to magnum cartridges, or hunters in dense brush. The 6.5×300 Weatherby Magnum ammunition costs between $4.50 and $8 per round, making routine practice expensive, and its recoil impulse demands proper technique. Hunters who primarily take shots under 200 yards in thick timber will find the 46-inch length cumbersome compared to something like the Stevens 334 in .308 Win. This is a tool for a specific, demanding niche.
What's in the box?
You receive the complete rifle with the PEAK 44 Bastion stock installed, one detachable 3-round steel magazine, factory-installed Accubrake ST, and a basic set of paperwork including the warranty card. The barrel is already threaded at 5/8×24 TPI but does not include a thread protector or a muzzle device beyond the brake. Weatherby does not include a hard case—shipment is in a cardboard carton with foam inserts, so plan for an aftermarket transport solution immediately.
Is the Weatherby Alpine ST worth it at $1899?
At $1,899, the Alpine ST offers tangible value for the shooter who needs its specific capabilities and can afford its operating costs. You are paying for a proprietary, high-performance cartridge platform, a premium carbon-fiber stock, and the weight-reducing spiral fluting on the 26-inch barrel. For the elk hunter covering five vertical miles in a week who needs a 500-yard capability, it's justifiable. For the average deer hunter, a standard .300 Win Mag or even a .30-06 in a cheaper rifle is a more practical allocation of funds.

Pros & cons
What works
- Weighs 9.35 lbs — nearly 2 lbs lighter than a comparable walnut-stocked magnum rifle for alpine carry.
- 26-inch fluted barrel with 1:8" twist stabilizes long, heavy-for-caliber 6.5mm bullets essential for long-range energy retention.
- 5/8×24 threaded muzzle accepts standard .30-cal suppressors and brakes without requiring an adapter or gunsmithing.
- PEAK 44 Bastion carbon-fiber stock provides rigid bedding for the action while significantly reducing overall mass.
Trade-offs
- Proprietary 6.5×300 Weatherby Mag ammunition costs $5+ per round — practice is prohibitively expensive for most.
- Model 307 scope base footprint is non-standard — requires specific $50-$80 bases from Warne or EGW.
- 46-inch overall length is cumbersome in vehicles and tight hunting blinds — not a compact package.
- No factory thread protector included for the muzzle — a $15-$25 aftermarket purchase is necessary.

Frequently asked questions
- Is the threaded muzzle compatible with common .30-caliber suppressors?
- Yes, the 5/8×24 thread pitch is the standard for .30-caliber/7.62mm muzzle devices and most large-frame suppressors. Direct-thread mounts from companies like Dead Air, SilencerCo, and Griffin Armament will fit. Remember that adding a 7-inch suppressor will increase the overall length to approximately 53 inches, which may require a specific ATF Form 1 or Form 4 registration if you configure it as a permanent fixture.
- Does the Model 307 action accept Remington 700-pattern scope bases?
- No, it does not. The Weatherby Model 307 action uses its own proprietary scope base footprint. You must purchase bases specifically labeled for the Weatherby Model 307. Seek out models from manufacturers like Warne, EGW, or Talley. The receiver is pre-drilled and tapped for these bases using a 6-48 screw thread, which is also industry standard, but the spacing is unique.
- How long does shipping to an FFL typically take?
- Processing and ground shipping from our warehouse to your chosen Federal Firearms License holder typically takes 7 to 10 business days, excluding weekends and holidays. Once the rifle arrives at your FFL, you must complete the required Form 4473 and pass the National Instant Criminal Background Check System check before taking possession. We ship via FedEx with adult signature-required delivery and full insurance coverage.
- Can I return it if I haven't fired it?
- Yes, we accept returns on unfired, undamaged firearms within 30 days of your FFL's recorded delivery date. The firearm must be in its original packaging with all accessories and paperwork, and you are responsible for coordinating and paying for shipping back to our facility through an FFL. A 15% restocking fee applies. Once a firearm has been fired, it is considered used and is not eligible for return under any circumstances.
- Does this work with aftermarket magazines?
- It is designed to work only with Weatherby-manufactured Model 307 detachable magazines for the 6.5×300 Weatherby Magnum cartridge. Aftermarket options from companies like Magpul or Accurate-Mag do not currently exist for this specific caliber and action combination. The single included 3-round steel magazine has a suggested retail price of $79.95, so factor in the cost of at least one spare into your initial budget.
