About this product
What is the Weatherby Vanguard Obsidian .300 Win Mag — Threaded Barrel? It's a bolt-action hunting rifle chambered in .300 Winchester Magnum with a 1/2×28 threaded muzzle for suppressor or brake attachment. Built on Weatherby's proven Vanguard action, this rifle combines match-grade features with synthetic stock durability for all-weather field use. The 44.5-inch overall length and 7.5-pound weight make it manageable for extended carries while maintaining stability for long-range shots.
What is the Weatherby Vanguard Obsidian used for?
This rifle is designed for long-range hunting and precision shooting in adverse conditions. The .300 Win Mag cartridge delivers 3,240 ft-lbs of energy at the muzzle, making it effective for elk, moose, and bear at distances beyond 400 yards. The synthetic stock resists moisture warping, and the threaded barrel accepts muzzle devices to reduce recoil or attach suppressors where legal.
How does the Weatherby Vanguard Obsidian compare to the Stevens 334 Rifle?
The Vanguard Obsidian outperforms the Stevens 334 Rifle in long-range precision and cartridge power. While the Stevens 334 in .308 Win offers a lighter 6.8-pound weight and lower $429 price point, the Weatherby's .300 Win Mag delivers 40% more energy at 500 yards and includes a match-grade two-stage trigger versus the Stevens' basic single-stage unit. For mountain hunting or ethical shots beyond 300 yards, the Weatherby is the clear choice.
What does it weigh and what are the dimensions?
The rifle weighs 7.5 pounds (120 ounces) and measures 44.5 inches in overall length. Barrel length is 24 inches with a 1:10 twist rate, and the synthetic stock has a 13.5-inch length of pull. The three-round magazine capacity keeps weight down compared to five-round designs, and the 44.5-inch length requires careful consideration for vehicle or safe storage.
Who is this NOT for?
This rifle is not for beginners or recoil-sensitive shooters. The .300 Win Mag generates 30 ft-lbs of felt recoil in this 7.5-pound platform, which is 50% more than a .308 Winchester in a similar weight rifle. Urban shooters or those limited to 100-yard ranges should consider the Stevens 334 in .243 Win for lower cost and milder recoil.
What's in the box?
The rifle ships with one three-round hinged floorplate magazine and no additional accessories. Unlike some competitors, Weatherby does not include thread protectors or optic mounting hardware—expect to add $40-$60 for a basic thread protector and rings. The manual includes torque specs for the 1/2×28 threads (18-20 ft-lbs maximum) and trigger adjustment procedures.
Is the Weatherby Vanguard Obsidian worth it at $581.99?
At $581.99, this rifle delivers exceptional value for hunters needing long-range capability. The match-grade trigger alone would cost $150 aftermarket, and the threaded barrel adds $100-$200 to most factory rifles. Compared to custom builds starting at $1,200, the Weatherby provides 90% of the performance for half the price, making it ideal for backcountry hunters or those experimenting with suppressors.

Trade-offs

Frequently asked questions
- Is the threaded barrel compatible with SilencerCo Omega 300?
- Yes, the 1/2×28 threads are compatible with SilencerCo Omega 300 suppressors using their direct-thread adapter. Always apply anti-seize compound and torque to 18 ft-lbs per SilencerCo's specification. The 24-inch barrel length provides sufficient clearance for most .30 caliber suppressors without contact.
- Does it come with iron sights?
- No, the Vanguard Obsidian ships without iron sights—it requires optic mounting. The receiver is drilled and tapped for standard Remington 700 pattern bases. Plan for $80-$150 for rings and bases, and another $50 for installation if you lack torque tools.
- How long does shipping take to Montana?
- Shipping to Montana takes 3-5 business days via FedEx Ground from our Nevada warehouse. All firearms ship to your local FFL dealer, who may add 1-2 days for transfer processing. We email tracking within 24 hours of shipment confirmation.
- Can I return it if it doesn't cycle properly?
- Returns are accepted within 30 days for manufacturing defects like extraction issues or trigger malfunctions. You must ship through an FFL dealer at your cost ($40-$80), and we inspect before refund. Ammunition-related cycling problems are not covered—test with Federal Premium 180gr ammo first.
