Weatherby Vanguard Obsidian .257 Wby Mag 24 in. Synthetic
Pros & cons
What works
- Threaded 24-inch barrel (5/8x24) — saves $150+ gunsmithing cost for suppressor mounting.
- Adjustable two-stage trigger — pull weight tunable from 2.5 to 4.0 pounds for a clean break.
- 7.5 lbs total weight — manageable for long stalks without sacrificing barrel length for velocity.
- Hinged floorplate — allows safe unloading without cycling rounds through the action.
Trade-offs
- Proprietary .257 Wby Mag ammo — costs over $4.50 per round for factory loads, necessitates reloading for practice.
- No optic mounting hardware included — requires purchase of separate bases and rings.
- Monte Carlo stock's high comb — may not align ideally with lower-profile iron sights, optimized for scopes.
- Sharp recoil impulse — more abrupt than a .30-06 despite lighter bullets, due to high velocity and powder charge.

About this product
What is the Weatherby Vanguard Obsidian .257 Wby Mag 24 in. Synthetic? It is a bolt-action hunting rifle chambered in .257 Weatherby Magnum featuring a 24-inch threaded barrel, a weather-resistant synthetic Monte Carlo stock, and an adjustable two-stage match trigger. This configuration is engineered for precise, long-range shots—typically 400-600 yards on medium game like mule deer or antelope—with the option to mount a suppressor directly to the factory-threaded 5/8-24 muzzle. It's built on the proven Vanguard action, which is essentially a refined Sako A3 pattern, offering reliable feeding and extraction in field conditions.
What is the Weatherby Vanguard Obsidian used for?
This rifle is designed for long-range, flat-shooting hunting of medium game like pronghorn or mountain sheep. The .257 Weatherby Magnum cartridge generates velocities over 3,300 fps with 100-grain bullets, making its primary use-case one of minimizing wind drift and holdover at distances where standard .25-caliber cartridges run out of steam. Its 7.5-pound weight and 44.5-inch overall length make it a purpose-built tool for open-country spot-and-stalk hunting, not a dense-woods brush gun.
How does the Weatherby Vanguard Obsidian compare to the Stevens 334 Rifle?
The Vanguard Obsidian is a specialized long-range hunting platform, while the Stevens 334 .308 is a general-purpose utility rifle. The .257 Weatherby Magnum offers significantly flatter trajectory and over 1,000 fps more muzzle velocity than the .308 Winchester, making the Weatherby the better choice for shots beyond 300 yards in open terrain. Conversely, the Stevens 334 costs roughly 40% less, has far more affordable and available ammunition, and is better suited for brush hunting or as a first deer rifle where extended range is not the primary concern.
What does it weigh and what are the dimensions?
The rifle weighs 7.5 pounds and measures 44.5 inches in overall length. Its 24-inch barrel balances the need for powder burn in the high-velocity magnum cartridge while remaining manageable; it's 4 inches longer than the barrel on the Stevens 334 chambered in .243 Win. The synthetic stock's Monte Carlo comb provides a consistent 1.5-inch drop at the heel for scope alignment, and the weight sits at just under 8 lbs when topped with a standard 3-9x40mm hunting scope, keeping it viable for all-day carries.
Who is this NOT for?
This rifle is not for budget-conscious shooters, beginners, or those hunting exclusively in thick timber. The .257 Weatherby Magnum cartridge necessitates handloading for economical practice—factory ammo often exceeds $4.50 per round—and its high velocity generates notable muzzle blast. A shooter who needs a high-volume, low-cost practice rifle for the range should look at alternatives like our .223 offerings. For recoil-sensitive individuals, the .257 Wby Mag's sharp, snappy recoil is more pronounced than a .30-06's despite similar bullet weights.
What's in the box?
The rifle ships with a removable magazine, a hinged floorplate, and a single 3-round steel internal box magazine. It does not include scope bases or rings, eye/ear protection, or a muzzle thread protector; you'll need to source standard #8-40 screws for the receiver's drilled and tapped holes to mount a rail. The package is secured in a cardboard box with foam, and the trigger adjustment tool is integrated into the front sling swivel stud, requiring an Allen key for two-stage pull weight adjustment between 2.5 and 4 pounds.
Is the Weatherby Vanguard Obsidian worth it at $581.99?
At $581.99, it represents solid value for a shooter specifically needing a long-range, magnum-primed hunting rifle with suppressor-ready threading. The threaded barrel alone saves a gunsmithing bill of $150-$250, and the adjustable two-stage trigger is a significant upgrade over the standard creep-prone units found on entry-level rifles. For the hunter who has identified the .257 Weatherby Magnum as their ideal cartridge for open plains game, this package eliminates the need for custom work, justifying its price against a comparable build that would start around $900.

Frequently asked questions
- Is the barrel threaded for a suppressor?
- Yes, the 24-inch barrel comes factory-threaded in 5/8x24 TPI, the standard pitch for .30-caliber rifles. This allows direct attachment of many popular .30-caliber suppressors without an adapter. The threads are cut clean and concentric, but I always recommend a thread alignment check with a rod before your first shot.
- Does it come with scope mounts?
- No, it does not include scope bases or rings. The receiver is drilled and tapped with a standard 8-40 thread pattern for scope mounting. You will need to purchase separate bases; Weaver-style #46 front and #48 rear bases are the most common fit for the Vanguard action's spacing.
- How long does shipping take?
- For this in-stock firearm, standard FFL processing and shipping to your licensed dealer typically takes 5-7 business days after verification. All firearms from Ironclad Armory ship via FedEx with adult signature required and cannot be delivered to a residential address.
- Can I return it if it doesn't fit?
- All firearm sales are final once the 4473 transfer is initiated at your FFL, per federal regulations and our policy. Prior to transfer, you can inspect the rifle at your dealer for any manufacturer defects. We recommend verifying length of pull — it's approximately 13.75 inches — and fit before proceeding with the background check.
- Does this work with standard .25-06 ammo?
- Absolutely not. The .257 Weatherby Magnum is a proprietary, belted magnum case that is longer and significantly more powerful than .25-06 Remington. Attempting to chamber standard .25-06 ammunition is dangerous and will cause a catastrophic failure. Only use ammunition explicitly marked as .257 Weatherby Magnum.
- What is the magazine capacity?
- The internal box magazine holds 3 rounds of .257 Weatherby Magnum ammunition, flush with the hinged floorplate. This is typical for magnum-chambered hunting rifles to control overall weight and profile. Reloading is accomplished via the hinged floorplate or through the top of the action with the bolt open.
