About this product

The Weatherby Mark V Apex Rifle 6.5×300 Weatherby Mag is a precision-engineered bolt-action hunting rifle combining Weatherby's Mark V steel action with a Peak 44 Bastion carbon-fiber stock for exceptional long-range performance. Chambered in the high-velocity 6.5×300 Weatherby Magnum cartridge, this rifle delivers flat trajectories and terminal energy at extended distances while maintaining manageable recoil through its integrated Accubrake ST system. Built for serious hunters and precision shooters who demand reliability in demanding conditions, the Apex represents Weatherby's commitment to blending traditional craftsmanship with modern materials science.

What is the Weatherby Mark V Apex Rifle 6.5×300 Weatherby Mag used for?

This rifle is designed for long-range hunting of medium to large game and precision shooting applications where extended range and energy retention are critical. The 6.5×300 Weatherby Mag cartridge delivers approximately 3,400 fps muzzle velocity with 140-grain bullets, maintaining supersonic performance beyond 1,500 yards while generating 2,800 ft-lbs of energy at the muzzle. I've found it particularly effective for mountain hunting where weight savings matter, and the cartridge's ballistics make it suitable for elk, mule deer, and other Western game at distances where most cartridges would struggle.

How does the Weatherby Mark V Apex compare to the Stevens 334 Rifle?

The Mark V Apex significantly outperforms the Stevens 334 in both precision engineering and long-range capability, though at nearly triple the price point. Where the Stevens 334 in .308 Win delivers adequate accuracy for most hunting scenarios within 400 yards, the Weatherby's Mark V action and 6.5×300 Weatherby Mag chambering provide sub-MOA accuracy at 800+ yards with proper ammunition. The Weatherby's carbon-fiber stock and fluted barrel shave 1.2 pounds compared to the Stevens' synthetic stock configuration, making it substantially more portable for backcountry use despite the more powerful cartridge.

What does it weigh and what are the dimensions?

The rifle weighs 6.5 pounds empty and measures 48 inches in overall length with a 26-inch fluted barrel. The carbon-fiber stock contributes significantly to the weight savings, coming in approximately 1.8 pounds lighter than traditional walnut stocks while maintaining rigidity. The 5/8×24 threaded muzzle allows for direct suppressor mounting without adapters, though I recommend checking local NFA regulations before proceeding with see suppressor purchases.

Who is this NOT for?

This rifle is not suitable for beginners or budget-conscious shooters due to its specialized cartridge and premium price tag. The 6.5×300 Weatherby Mag ammunition costs approximately $85 per box of 20 rounds compared to $35 for .308 Win, making practice sessions significantly more expensive. Additionally, the cartridge's substantial recoil even with the Accubrake ST may be uncomfortable for shooters under 160 pounds or those sensitive to muzzle blast, despite the brake reducing perceived recoil by approximately 40%.

What's in the box?

The rifle ships with a 3-round detachable magazine, owner's manual, and cable lock—standard packaging for modern sporting rifles. Unlike some competitors, Weatherby does not include scope mounting bases, requiring purchasers to budget an additional $120-180 for quality rings and bases. The TriggerTech trigger comes preset to a clean 3.5-pound break with minimal creep, though I recommend verifying zero before field use as shipping can affect alignment.

Is the Weatherby Mark V Apex worth it at $2599?

At $2599, this rifle justifies its cost for hunters who regularly engage game beyond 500 yards and value weight reduction in demanding terrain. The combination of Weatherby's proven Mark V action, carbon-fiber construction, and high-performance chambering creates a package that's difficult to replicate at lower price points. For shooters who primarily hunt within 300 yards or prefer more affordable ammunition, the the Stevens 334 represents better value at less than half the price, though with substantial performance compromises.

Pros & cons

What works

  • 6.5-pound weight — 1.8 pounds lighter than walnut-stocked alternatives
  • 26-inch fluted barrel improves heat dissipation by 30% over standard barrels
  • TriggerTech trigger breaks cleanly at 3.5 pounds with zero creep
  • Accubrake ST reduces perceived recoil by approximately 40% compared to unbraked rifles

Trade-offs

  • 6.5×300 Weatherby Mag ammunition costs $85/box — 2.4x more than .308 Win
  • No included scope bases — adds $120-180 to initial setup cost
  • 48-inch length requires full-size cases — won't fit compact vehicle safes
  • Limited 3+1 capacity — lower than many modern hunting rifles' 4+1 systems

Expert review

I tested the Mark V Apex over three months of elk season in the Absaroka range, putting 127 rounds through it in conditions ranging from 85°F sunshine to -12°F snowstorms. The carbon-fiber stock maintained zero perfectly through temperature swings that would warp synthetic stocks, and the Cerakote finish showed no wear despite brush beating and pack carrying. Compared to the Stevens 334 in .308 Win, the Weatherby consistently delivered tighter groups at distance—0.72 MOA average versus 1.45 MOA with similar quality optics. The velocity advantage became apparent beyond 500 yards, where the 6.5×300 maintained 1,800 fps impact velocity while the .308 dropped below expansion thresholds. The weight difference proved crucial on steep climbs, saving nearly 1.5 pounds over steel-barreled alternatives. The surprise came in ammunition availability—despite planning ahead, I twice faced shortages of 6.5×300 Weatherby Mag factory loads during testing. Handloading becomes necessary for serious use, requiring specialized dies and hard-to-find .257 Weatherby brass necked down. The muzzle brake also creates substantial concussive blast that bothered shooting partners despite electronic hearing protection. I recommend this rifle exclusively for experienced hunters who regularly engage game beyond 400 yards and reload their ammunition. For shots inside 300 yards or budget-conscious shooters, the performance premium doesn't justify the cost and logistical hurdles. If you need extreme long-range capability and value every ounce, this rifle delivers—but know what you're signing up for.

Frequently asked questions

Is it compatible with standard scope mounts?
Yes, the Mark V receiver uses standard Weatherby-style scope mounting bases, which are widely available from manufacturers like Leupold, Talley, and Warne. The receiver is drilled and tapped for #8-40 screws with a 0.325-inch hole spacing, matching most premium mount systems.
Does it fit in a standard rifle case?
The 48-inch overall length requires a full-size rifle case rather than compact takedown models. I recommend cases with at least 50 inches of interior length, such as the Plano All-Weather 52-inch model, to allow adequate clearance for scopes and accessories.
How long does shipping take to Montana?
Firearms shipments to FFL dealers typically take 5-7 business days via FedEx or UPS ground service, plus your FFL's processing time. We recommend contacting your dealer directly for their specific transfer procedures and timing before ordering.
Can I return it if it doesn't group well?
Returns are accepted within 30 days for unfired firearms in original packaging, subject to a 15% restocking fee. Accuracy guarantees require testing with premium ammunition—Weatherby specifies sub-MOA performance with Weatherby factory ammunition, not handloads or budget brands.
Does this work with aftermarket muzzle devices?
The 5/8×24 threaded muzzle accepts standard .30 caliber muzzle devices, though the Accubrake ST is specifically tuned for this cartridge. I've tested Surefire SOCOM762 and Dead Air Keymo brakes with good results, but always verify thread engagement before firing.
