Weatherby Mark V Accumark .300 Weatherby Magnum, Graphite Black
About this product
The Weatherby Mark V Accumark .300 Weatherby Magnum, Graphite Black is a precision-oriented bolt-action rifle built on the legendary Mark V action for long-range big-game hunting and target shooting. It's chambered in the powerful .300 Weatherby Magnum cartridge and features a hand-laid fiberglass stock, fluted barrel, and TriggerTech trigger. This rifle is designed for shooters who demand consistent sub-MOA accuracy under field conditions where shot placement matters more than round count.
What is the Weatherby Mark V Accumark .300 Weatherby Magnum used for?
The Weatherby Mark V Accumark .300 Weatherby Magnum is primarily used for ethical, long-range harvesting of North American big game like elk, moose, and bear at distances beyond 300 yards. The cartridge produces 3,880 ft-lbs of muzzle energy—enough for clean takedowns—while the rifle's 48.25-inch overall length requires deliberate handling in tight timber. The Accubrake muzzle brake reduces recoil by an estimated 40%, making extended practice sessions tolerable, though your range partners will appreciate you shooting before they set up.
How does the Weatherby Mark V Accumark compare to the Stevens 334?
The Weatherby Mark V Accumark is fundamentally different from a budget rifle like the Stevens 334 in .308 Win—it's a purpose-built tool where the Stevens is a general-purpose implement. The Accumark's TriggerTech Field trigger breaks at a consistent 2.5 pounds with zero creep, while the Stevens' factory trigger averages 5.5 pounds with noticeable grit. The Accumark's 1:10 twist rate stabilizes heavier 190-220 grain bullets for better long-range performance, whereas the .308's 1:10 twist struggles past 600 yards with equivalent bullet weights. For hunting elk at 400+ yards, the Accumark is objectively superior; for whitetail at 150 yards, the Stevens represents better value.
What does it weigh and what are the dimensions?
The Weatherby Mark V Accumark weighs 8.3 lbs (3.76 kg) unloaded, measures 48.25 inches (122.6 cm) overall, and has a 26-inch (66 cm) fluted barrel with a #3 contour profile. Compare this to the Stevens 555 Sporting Compact shotgun at 6.2 lbs and 42 inches—the Accumark carries like a serious precision instrument, not a brush rifle. Barrel fluting removes approximately 12 ounces of weight while maintaining stiffness, and the Monte Carlo stock adds 1.25 inches of comb height for consistent optic alignment. Expect another 1.5-2 lbs when mounting a typical 3-15x magnification scope and rings.
Who is this NOT for?
This rifle is not for casual plinkers, budget-conscious hunters, or shooters recoil-sensitive to magnum cartridges. The .300 Weatherby Magnum generates over 30 ft-lbs of recoil energy in a bare configuration—significantly more than a .308 Winchester's 17 ft-lbs—and factory ammunition costs $4-8 per round. The 8.3 lb weight becomes noticeable after 6 hours carrying in steep terrain, and the 48.25-inch length makes vehicle transport cumbersome without breaking it down. If you primarily hunt deer in wooded areas under 200 yards, you're paying for capability you'll never use while acquiring a firearm less suited to your actual environment.
What's in the box?
From Ironclad Armory, you receive the Weatherby Mark V Accumark rifle with Accubrake muzzle brake installed, one 3-round steel magazine (total 3+1 capacity with chambered round), a thread protector, and basic owner's manual with torque specifications. We ship it in a hard Plano case with foam bedding, which adds 12 lbs to the shipping weight. We do not include scope bases, rings, optics, or hearing protection—plan an additional $300-600 for proper mounting hardware and $800-2,000 for a suitable long-range optic. The muzzle brake requires a 1-1/16" wrench for removal, which is not included.
Is the Weatherby Mark V Accumark worth it at $1,999?
At $1,999, the Weatherby Mark V Accumark represents appropriate value for hunters requiring consistent accuracy at extreme distances with a magnum cartridge. The combination of the Mark V action ($900+ if purchased separately), TriggerTech trigger ($180), hand-laid fiberglass stock ($400+), and fluted barrel justify the price compared to custom builds starting at $3,500. However, the Stevens 334 in .308 Win at $449 will ethically take the same game at moderate ranges—you're paying $1,550 premium for the Weatherby name, .300 Weatherby Magnum chambering, and precision features that only matter past 300 yards. If your shots regularly exceed that distance, yes; if not, the premium is difficult to justify.

Frequently asked questions
- Is the receiver drilled and tapped for scope mounts?
- Yes, the Weatherby Mark V Accumark receiver is drilled and tapped with standard #8-40 screws at 6.5" spacing for scope bases. Weaver-style bases from manufacturers like Talley, Leupold, or Nightforce will mount directly. We recommend torquing bases to 25 in-lbs using a calibrated wrench, not an impact driver.
- Does the Accubrake muzzle brake thread off for a suppressor?
- The Accubrake is permanently pinned and welded to meet the 26" overall barrel length requirement—removal requires a gunsmith with a lathe and re-pinning. The barrel's muzzle is not threaded for suppressors. If you want to suppress this rifle, order a custom barrel or contact Weatherby for a non-brake configuration (lead time 8-12 weeks).
- How long does shipping to an FFL take?
- Ironclad Armory ships within 2 business days after FFL verification, with transit times of 3-5 days via FedEx Ground. Total delivery typically takes 7-10 business days from order to your chosen FFL holder. We require adult signature confirmation and do not ship to PO boxes or private addresses—only verified FFL dealers on file.
- What ammunition does this rifle prefer?
- The 1:10 twist rate stabilizes bullets from 150 to 220 grains, with optimal accuracy typically between 180-200 grains. Weatherby factory ammunition (180gr Nosler Partition) groups around 1.1 MOA; handloads with 200gr ELD-X bullets and 81.5 grains of H1000 powder consistently achieve 0.75 MOA. Avoid lightweight 150-grain bullets for hunting—they shed velocity quickly past 300 yards.
- Can I return it if I don't like the recoil?
- Ironclad Armory accepts returns within 30 days for unused firearms in original packaging, subject to a 15% restocking fee and return shipping costs ($75-125). However, we cannot accept returns due to buyer's remorse about recoil—test fire a .300 Weatherby Magnum at a range before purchasing. All returns require advance RMA authorization and must ship from an FFL to our FFL.
