Weatherby Vanguard Obsidian .350 Legend 20″ Heavy Threaded
About this product
The Weatherby Vanguard Obsidian .350 Legend 20″ Heavy Threaded is a purpose-built bolt-action rifle that bridges the gap between modern straight-wall cartridge performance and the time-honored craftsmanship Weatherby has delivered since 1945. Chambered in .350 Legend, this model features a 20-inch cold hammer-forged heavy barrel with factory threading, a Monte Carlo black synthetic stock, and a blued finish that stands up to hard use in the field. Designed for consistent on-target performance, the Obsidian HB pairs Weatherby's match-grade trigger with an overall length that balances well for both prone shooting and still-hunting. The .350 Legend cartridge offers straight-wall ballistics that meet state regulations for deer and bear seasons, while the heavy barrel profile keeps groups tight round after round. Whether you are punching paper at the range or tracking a whitetail through the timber, the Vanguard Obsidian delivers repeatable accuracy and rugged reliability.

Key Features
- Cold Hammer-Forged Barrel — Why it matters: The hammer-forging process aligns the steel grain structure for exceptional uniformity and longevity, meaning you can expect sub-MOA accuracy from the factory and a barrel that holds its edge through thousands of rounds.
- Match-Grade Trigger — Why it matters: Weatherby's two-stage trigger breaks cleanly at a user-adjustable pull weight, eliminating creep and let-off inconsistency that can throw a shot at the moment of truth.
- 20″ Heavy Threaded Barrel — Why it matters: The heavy contour absorbs heat and vibration for sustained precision, while the factory threading (5/8×24) allows direct mounting of muzzle brakes or suppressors without a gunsmith visit.
- Monte Carlo Synthetic Stock — Why it matters: The raised cheekpiece aligns your eye naturally with the scope, and the synthetic material resists warping from moisture or temperature swings, keeping your zero stable in wet or cold conditions.
- Blued Finish with Durable Synthetic Furniture — Why it matters: The blued steel provides a corrosion-resistant surface that stands up to sweat and light rain, while the synthetic stock sheds mud and snow without adding weight.
Who It’s For
This rifle is for the hunter who needs a straight-wall cartridge to comply with state regulations yet refuses to sacrifice accuracy. It suits the collector who appreciates Weatherby's legacy of precision engineering and the shooter who wants a ready-to-run platform that doesn't require immediate aftermarket upgrades. If you value a rifle that shoots as well out of the box as many custom builds, the Vanguard Obsidian is your match.
Pros & Cons
- Pros: Factory threaded barrel for suppressor use; match-grade trigger out of the box; heavy barrel profile for consistent accuracy; synthetic stock is weather-resistant; .350 Legend offers low recoil with good terminal ballistics.
- Cons: The Monte Carlo stock may not suit shooters who prefer a more vertical grip angle; the .350 Legend cartridge has limited factory ammunition variety compared to .308 Win or 6.5 Creedmoor.

FAQ
What is the barrel twist rate on the Weatherby Vanguard Obsidian .350 Legend?
The barrel twist rate is 1:16 inches, per Weatherby specs, which stabilizes the .350 Legend's 180-grain and 200-grain projectiles effectively for hunting and target use.
Does the rifle come with scope rings or a rail?
Yes, the Vanguard Obsidian includes a factory-installed two-piece scope base (Weaver-style) that accepts standard rings. Rings are not included, so you will need to purchase those separately based on your scope tube diameter.
Is the barrel threaded for a suppressor?
Yes, the 20″ heavy barrel is factory threaded with a 5/8×24 thread pattern, and a thread protector is included. This allows direct attachment of most .30-caliber suppressors.
What is the overall length of this rifle?
The overall length is 44 inches, which keeps it maneuverable in a blind or stand while still providing a solid sight radius for iron sights or a scout scope.
Does the .350 Legend require special ammunition?
The .350 Legend uses straight-wall cartridge dimensions, so it requires .350 Legend-specific ammunition. It is widely available from major manufacturers like Winchester, Federal, and Hornady, and it is legal for deer hunting in several straight-wall-only states.
