Weatherby Mark V Deluxe 340 WBY Mag 26″ Right Hand
Pros & cons
What works
- Mark V 9-lug action withstands 65,000+ PSI - 25% stronger than standard Mauser-type actions
- TriggerTech adjustable trigger breaks at a crisp 3.5 lbs - 1.5 lbs lighter than most factory rifle triggers
- Pachmayr Decelerator pad reduces felt recoil by approximately 20% compared to standard hard rubber pads
- 1:10 twist barrel stabilizes long, heavy bullets up to 250 grains for optimal ballistic performance
Trade-offs
- Non-threaded barrel requires $150-$250 gunsmith work to add muzzle brake for recoil management
- High-gloss blued finish shows scratches and wear immediately in field use - not a durable finish
- Ammunition costs ~$7 per round - a 20-round box equals $140, making practice sessions expensive

About this product
The Weatherby Mark V Deluxe 340 WBY Mag 26″ Right Hand is a premium bolt-action magnum rifle that combines classic walnut-and-bluing aesthetics with modern precision engineering for experienced hunters and long-range shooters. Built on Weatherby's proprietary 9-lug Mark V action, it handles the potent 340 Weatherby Magnum cartridge, a round designed for terminal performance at extreme distances. The rifle represents a specific intersection of traditional craftsmanship and controlled-power mechanics that demands respect from the operator.
What is the Weatherby Mark V Deluxe 340 WBY Mag used for?
This rifle is designed for hunting large, dangerous game at long range in open terrain, such as pursuing elk in Montana or moose in Alaska. The 340 WBY Mag cartridge launches heavy bullets at velocities exceeding 2,900 feet per second, generating over 5,000 foot-pounds of muzzle energy for decisive knockdown power. Its 46.63-inch overall length and 8.25-pound weight make it a dedicated field rifle, not a casual plinker, requiring disciplined shooting form to manage substantial recoil.
How does the Weatherby Mark V Deluxe compare to the Stevens 334 Rifle?
The Mark V Deluxe is a specialized magnum hunting platform, while the Stevens 334 in .308 Win is a general-purpose utility rifle. The Weatherby's 9-lug action is significantly stronger and heavier, built to withstand the 65,000+ PSI chamber pressures of the 340 WBY Mag, whereas the Stevens uses a simpler, lighter two-lug design for standard cartridges. The Mark V's TriggerTech unit offers a crisper, more adjustable 2.5-to-4 pound pull compared to the Stevens' basic factory trigger, and its Gloss AA walnut stock provides superior rigidity and fit over synthetic alternatives for precision shooting.
What does it weigh and what are the dimensions?
The rifle weighs 8.25 pounds (132 ounces) unloaded and without optics. Its overall length is 46.63 inches, with a 26-inch non-threaded barrel featuring a 1:10 twist rate optimized for stabilizing long, heavy bullets up to 250 grains. The internal magazine holds 3 rounds, plus 1 in the chamber, for a total capacity of 4 rounds—a practical limit for a magnum rifle where each shot is deliberate and reloading is not a rapid tactical exercise.
Who is this NOT for?
This rifle is not for new shooters, budget-conscious hunters, or anyone seeking a lightweight mountain rifle. The 340 WBY Mag generates punishing recoil exceeding 40 foot-pounds, and ammunition costs roughly $7 per round, making practice prohibitively expensive for casual use. Furthermore, its high-gloss finish and checkered walnut stock are unsuitable for rugged, abusive backcountry conditions where a synthetic-stocked, matte-finished rifle like the Stevens 334 in .243 Win would be more practical and durable.
What's in the box?
The rifle ships alone, with no optics, sling, or case included. It arrives from the factory with the Pachmayr Decelerator recoil pad installed, the receiver drilled and tapped for scope mounts (using standard 6-48 screws), and the TriggerTech factory-set to a 3.5-pound pull. You must purchase and install scope bases, rings, and a scope capable of withstanding the rifle's significant recoil impulse—a process that typically adds $300-$1,500 to the total system cost before a single round is fired.
Is the Weatherby Mark V Deluxe worth it at $2,999?
Yes, but only for the specific shooter who requires its magnum power and appreciates its traditional craftsmanship. At this price, you are paying for the Mark V action's legendary strength and the labor-intensive finish on the AA walnut stock—features absent from production rifles costing half as much. If your hunting involves shots inside 300 yards on deer-sized game, a standard .30-06 or .300 Win Mag is a more economical and forgiving choice, saving you money on both the rifle and ammunition.

Frequently asked questions
- Is the barrel threaded for a muzzle brake or suppressor?
- No, this specific 26-inch Mark V Deluxe configuration features a non-threaded, crowned muzzle. Threading the barrel for a muzzle device would require a certified gunsmith, cost approximately $150-$250, and may compromise the factory bluing. If you require a threaded magnum rifle, you must select a different factory model or have this one modified.
- Does it come with scope bases installed?
- No, the receiver is only drilled and tapped for scope mounts. You must purchase and install separate bases. Weatherby Mark V actions typically use a proprietary two-piece base pattern; we recommend Warne or Leupold steel bases, which require 6-48 mounting screws torqued to 15-18 inch-pounds for secure attachment under recoil.
- What is the lead time for shipment?
- As an 'Online Only' item, this rifle ships directly from our distributor network. Current lead time is 7-10 business days for processing and FFL shipment confirmation. You must provide your receiving FFL dealer's license before shipment, and final transfer happens at their location following a NICS background check.
- Can I return it if I can't handle the recoil?
- No, firearms sales are final for safety and regulatory compliance once the transfer is initiated at your FFL. We strongly suggest you test-fire a 340 WBY Mag or similar magnum cartridge at a rental range before purchasing. This policy is standard across the industry to prevent unnecessary handling and potential damage to a finely tuned firearm.
- What scope magnification is recommended for this cartridge?
- Given the 340 WBY Mag's effective range beyond 500 yards, a variable-power scope with a minimum of 4-5x on the low end and 16-20x on the high end is appropriate. The rifle's substantial recoil mandates a scope built for heavy magnums, such as models from Leupold's VX-5HD or Nightforce SHV series, which are tested to withstand over 1,000 G's of shock.
