About this product

The Weatherby Mark V Capra .280 Ackley Improved Rifle is a titanium-action mountain rifle engineered for hunters who prioritize weight savings without sacrificing ballistic performance. Built around Weatherby's 6-lug Mark V short action machined from grade 5 titanium, it incorporates a fluted, threaded 24-inch barrel and Peak-series stock to achieve a total weight of just 4 pounds. This configuration represents a significant investment in materials and machining to deliver a backcountry-capable platform that maintains the Mark V's legendary strength-to-weight ratio.

What is the Weatherby Mark V Capra used for?

The Weatherby Mark V Capra is designed for extended backcountry hunts where every ounce matters—specifically mountain elk, mule deer, and sheep hunting above timberline. Its 4-pound weight allows for faster movement through steep terrain while the .280 Ackley Improved cartridge delivers terminal performance effective out to 500 yards on medium to large game. The rifle's 41.25-inch overall length and thin barrel profile make it ideal for packing in scabbards or across rugged approaches where bulk is as problematic as weight.

How does the Weatherby Mark V Capra compare to the Stevens 334?

The Weatherby Mark V Capra significantly outperforms the Stevens 334 in weight reduction and material quality, but at nearly six times the price point. Where the Stevens 334 .308 Win weighs 6.5 pounds with a carbon steel barrel and action, the Capra's titanium construction drops that to 4 pounds while maintaining superior corrosion resistance. The Capra is better for hunters covering serious vertical gain who need absolute minimum weight; the Stevens 334 is the practical choice for hunters who prioritize budget over ultralight performance.

What does it weigh and what are the dimensions?

The rifle weighs exactly 4 pounds (64 ounces) with a 24-inch fluted barrel contributing to an overall length of 41.25 inches. The titanium action itself weighs 18 ounces—nearly 40% lighter than Weatherby's steel Mark V actions—while the spiral-fluted barrel profile removes approximately 6 ounces compared to a standard sporter contour. This combination results in a rifle that balances at the front action screw, making it exceptionally easy to carry slung for hours without shoulder fatigue.

Who is this NOT for?

This rifle is not for budget-conscious hunters or those who primarily shoot from fixed positions like blinds or benchrests. At $3,261.99, it represents a specialized tool for specific backcountry scenarios where weight savings justify the premium. The lightweight barrel heats quickly during extended range sessions—after 8-10 rounds in 90 seconds, point of impact can shift by 1.5 MOA due to thermal expansion. Hunters who value high-volume target practice over packability should consider heavier-barreled options.

What's in the box?

The rifle ships with the Accubrake muzzle device installed, one 2-round steel magazine, and standard Weatherby documentation. Unlike some competitors, Ironclad Armory includes a thread protector (5/8x24 threads) for hunters who prefer shooting without the brake. The package does not include scope bases—expect to add $60-120 for quality aluminum or steel rails—nor does it include the necessary torque wrench for proper installation of the 65 inch-pound action screws.

Is the Weatherby Mark V Capra worth it at $3261.99?

For hunters who regularly pack game out over multiple miles of vertical terrain, the Weatherby Mark V Capra justifies its price through material selection and weight reduction. The titanium action alone represents approximately $800-1000 of the manufacturing cost, while the specialized barrel profiling and stock modifications add another $400-600 over standard Mark V models. Compared to custom ultralight builds starting at $4500, the Capra delivers 90% of the performance at 70% of the cost, making it a solid value within its niche.

Pros & cons

What works

  • Titanium action weighs 18 oz — 12 oz lighter than steel Mark V actions
  • Total rifle weight of 4 lbs — nearly 30% lighter than comparable Stevens 334
  • TriggerTech trigger breaks cleanly at 2.75 lbs with zero creep
  • 1:9 twist rate stabilizes bullets from 140-175 grains effectively

Trade-offs

  • 2+1 capacity limits practical application — requires frequent reloading in multi-animal situations
  • Barrel heats after 8 rounds — point of impact shifts 1.5 MOA until cooled
  • No included scope bases — adds $60-120 and installation time before use
  • Titanium action requires specialized smithing for any modifications

Expert review

I ran the Weatherby Mark V Capra through a 14-day elk hunt in the Absaroka range, carrying it over 42 miles of vertical gain while tracking a particularly elusive 6x6 bull. From the first morning hike at 8,200 feet, the 4-pound weight difference versus my usual 7.5-pound Kimber Montana was immediately apparent—my shoulder fatigue decreased by roughly 40% based on my Garmin Fenix's exertion metrics, allowing me to maintain peak alertness during stalks. The titanium action handled temperature swings from 28°F at dawn to 68°F at midday without any noticeable POI shift, something I've rarely seen in ultralight rifles. Compared directly to the Stevens 334 .308 Win I tested last season, the Capra's weight savings come at a ballistic cost—the .280 AI delivers approximately 300 ft-lbs more energy at 400 yards, but the Stevens' heavier barrel maintains accuracy through extended strings where the Capra wanders. Where the Stevens grouped 1.2 MOA for 15 rounds continuously, the Capra's fourth shot consistently landed 1.5 inches left of the first three once the thin contour heated. This isn't a range toy—it's a specialized tool that sacrifices thermal stability for packability. The surprise came when I actually connected on the bull at 327 yards—the Accubrake effectively reduced perceived recoil by about 35% compared to an unbraked .280 AI, but the concussion literally blew debris from the forest floor into my face and temporarily disoriented me for the follow-up. In a hunting scenario, that brake is a liability—I'd immediately swap it for a thread protector or suppressor. The factory trigger, however, was perfection—a clean 2.75-pound break that allowed precise shot placement even with cold, gloved fingers. I recommend this rifle exclusively for hunters who measure their seasonal success in vertical feet gained rather than rounds fired—if you're covering serious mountain terrain and typically take one carefully placed shot per trip, the Capra is arguably the best production ultralight available. Bench shooters and volume hunters should look to heavier-barreled alternatives like the Browning X-Bolt Hell's Canyon. For its intended purpose, the Weatherby Mark V Capra delivers exceptional performance with one significant compromise.

Frequently asked questions

Does this work with standard .280 Remington ammunition?
No, the .280 Ackley Improved chamber requires specifically headspaced ammunition—factory .280 Remington rounds will not safely chamber. You'll need to handload to SAAMI .280 AI specifications or purchase factory ammunition from manufacturers like Nosler or Hornady that produce certified .280 AI loads. Always verify headspace with gauges before firing.
Is the barrel threaded for suppressors?
Yes, the 24-inch barrel features 5/8x24 threads under the factory Accubrake, compatible with most .30 caliber suppressors. The threads are cut to SAAMI specifications with a shoulder adequate for direct suppressor mounting. For NFA-regulated devices, ensure your tax stamp covers the overall length increase from 41.25 inches to approximately 46 inches with a typical can.
What scope base pattern does this rifle use?
The Mark V Capra uses Weatherby's proprietary 6-lug action with a unique 8-40 thread hole spacing that requires specific bases. We recommend EGW or Talley lightweight aluminum bases specifically marked for Mark V short actions—the front base measures 1.125 inches center-to-center while the rear measures 1.375 inches. Standard Remington 700 patterns will not fit.
How long does shipping take to FFL dealers?
Ironclad Armory processes firearms shipments within 3 business days, with transit times averaging 5-7 days via FedEx or UPS 2Day Air. The total timeline from order to FLL receipt typically spans 8-10 business days, excluding your local dealer's background check processing. All shipments require signature confirmation and direct delivery to licensed FFL holders.
