Weatherby Mark V Backcountry 2.0 .300 Wby Mag
About this product
The Weatherby Mark V Backcountry 2.0 .300 Wby Mag is a purpose-built, lightweight bolt-action magnum rifle designed for backcountry hunters who need to cover miles and shoot accurately. Built around Weatherby’s robust nine-lug Mark V action, its updates specifically target weight reduction and recoil management—critical for high-energy chamberings. At 6.20 pounds, it places itself directly in the ultralight rifle category but with features that aim to control a notoriously punishing cartridge.
What is the Weatherby Mark V Backcountry 2.0 used for?
The Mark V Backcountry 2.0 is engineered for backcountry hunting scenarios demanding carried weight savings and first-shot precision at extended ranges. I recommend it specifically for western hunts across steep terrain for elk or similar game, where hunters may cover 8-10 miles daily and final shots could range from 100 to 400 yards. Its .300 Weatherby Magnum chambering delivers the high retained energy needed for ethical takedowns at those distances, while the Accubrake ST makes managing the substantial recoil more practical for a follow-up shot.
How does the Weatherby Mark V Backcountry 2.0 compare to the Stevens 334 in .308 Win?
The Backcountry 2.0 is a superior tool for long-range, high-energy hunting, while the Stevens 334 is a better choice for budget-conscious or short-range hunters. The Weatherby’s .300 Wby Mag generates nearly 40% more muzzle energy than a .308 Winchester, making it dramatically more effective for large game at distance, but it also costs over twice as much and has more punishing recoil and ammo cost. The Stevens 334 in .308 is, frankly, a durable, budget workhorse for brush hunting or casual shooting where absolute precision and light weight are secondary to value.
What does it weigh and what are the dimensions?
The rifle weighs 6.20 pounds, with an overall length of 44 1/2 inches from buttpad to muzzle brake tip. The barrel itself is 24 inches long and threaded 5/8”-24, a common and useful pitch for mounting a variety of muzzle devices or a suppressor to manage the cartridge's blast. The weight centers on the receiver, creating a balance that feels surprisingly quick in the hands for a magnum, but the lighter construction will also transmit more felt recoil than a heavier rifle.
Who is this NOT for?
This is not a rifle for new shooters, budget hunters, or those planning high-volume range sessions. The .300 Weatherby Magnum round is expensive, averaging $4.00-$6.50 per factory round, and produces brutal recoil—even with the Accubrake ST. If you aren’t carrying it for miles or needing its extreme long-range energy for large game, the cost and recoil are unwarranted. It’s a specialized tool; a cheaper, heavier rifle in a milder cartridge like .30-06 is a smarter buy for most shooters.
What's in the box?
The rifle ships with the Accubrake ST muzzle brake installed, an empty polymer 3-round detachable magazine, and a standard action wrench for optics mounting. You are not getting a bipod, sling, scope, or soft case—the factory assumes you’re a serious hunter who will select those components based on your specific needs. The receiver is pre-drilled and tapped to Mil-STD 1913 specifications for immediate optics mounting, a crucial detail that prevents the need for a gunsmith before your hunt.
Is the Weatherby Mark V Backcountry 2.0 worth it at $2,499?
Yes, if you are an experienced hunter who specifically needs its combination of ultra-light weight and high-power, long-range capability. The price buys you a proven nine-lug Mark V action, a carbon-fiber stock that shaves ounces without sacrificing rigidity, and a recoil system that makes this cartridge manageable for a controlled pair of shots. It’s a targeted purchase that makes sense only for a specific class of backcountry hunt; if that isn’t your use case, consider more versatile and affordable options like the Stevens 555 Sporting for birds or a .308 for general-purpose shooting.

Pros & cons
What works
- Weighs 6.20 lbs — cuts crucial pounds on multi-day backcountry hikes.
- 24-inch fluted barrel with 5/8”-24 threads facilitates suppressor mounting for high-power cartridges.
- Accubrake ST muzzle brake reduces felt recoil by an estimated 30-35% versus an unbraked barrel.
- Peak 44 carbon-fiber stock is rigid in all weather, eliminating the moisture-dependent weight shift of traditional wood.
Trade-offs
- Proprietary 3+1 magazine design limits high-capacity options and replacement part availability.
- Patriot Brown Cerakote is a thin finish; expect visible wear marks on the action rails and barrel contact points after field use.
- Carbon-fiber stock lacks adjustable comb or length-of-pull, forcing a one-size-fits-all shooter interface.
- .300 Wby Mag ammunition costs $4+ per round — high round-count practice is prohibitively expensive.

Frequently asked questions
- What scope base fits this rifle?
- The receiver is drilled and tapped with #8-40 screws on a standard long-action two-piece base pattern. Use #8-40 screws; do not force #6-48 screws, as they will strip the receiver threads. Most major manufacturers, like Nightforce or Leupold, list these bases specifically for the Mark V long action.
- Is the barrel threaded for a suppressor?
- Yes, the 24-inch barrel has a 5/8”-24 thread pitch, which is the standard for .30 caliber suppressors. However, the factory-installed Accubrake ST muzzle brake must first be removed. Ensure you use a quality suppressor rated for .300 Weatherby Magnum pressures and apply anti-seize compound to the threads before installation.
- Does it take standard long-action magazines?
- No, it requires proprietary Weatherby Mark V .300 Wby Mag magazines. Third-party options are limited. This rifle shipped with a 3-round polymer magazine. The feed lips and follower are designed for the long, sloping shoulder of the Weatherby cartridge—a standard .300 Win Mag magazine will cause feeding jams.
- What is the lead time for shipping?
- Expect processing and ground shipping to take 7-10 business days to most locations, assuming the item is in stock and compliant with state and local regulations. Shipments to FFL dealers require an active, verified license on file before the order can ship. We recommend contacting your local FFL to confirm they will accept the transfer before ordering.
