Weatherby Mark V Accumark 28 Nosler 26″ Threaded/Fluted
About this product
The Weatherby Mark V Accumark 28 Nosler 26″ Threaded/Fluted is a purpose-built precision rifle configured for extreme long-range engagement with a chambering that generates high ballistic coefficient. It evolves from the Mark V action into a specialized tool through a fluted stainless barrel, an adjustable TriggerTech trigger, and a composite stock bedded for rigid support. For shooters navigating the 1,000+ yard envelope, this rifle provides a factory package optimized for that singular mission.
What is the Weatherby Mark V Accumark 28 Nosler used for?
This rifle is built for engaging targets at 1,000 yards and beyond, where flat trajectory and retained energy are non-negotiable. The 28 Nosler cartridge fires heavy, high-BC bullets at velocities exceeding 3,000 fps from the 26-inch barrel, making it effective on elk-sized game at extreme distances or for competitive long-range steel matches. The threaded muzzle and Accubrake ST configuration directly manage the substantial recoil impulse of this magnum cartridge, a necessity for maintaining sight picture and spotting impacts.
How does the Weatherby Mark V Accumark compare to the Stevens 334 Rifle?
The Accumark is a specialized, high-performance tool, while the Stevens 334 Rifle is a general-purpose, value-oriented hunting rifle. The Accumark's 28 Nosler chambering, premium trigger, and composite stock system are designed for sub-MOA precision at distances where the .308 Win chambering of the Stevens 334 begins to struggle with wind drift and drop. The Stevens 334 is better for budget-conscious hunters needing a reliable rifle within 500 yards, but the Accumark dominates in pure ballistic performance and long-range accuracy, justifying its higher cost for that specific role.
What does it weigh and what are the dimensions?
The rifle weighs 8.30 lbs (approximately 3.76 kg) and has an overall length of 46.25 inches (1,175 mm). The 26-inch (660 mm) fluted stainless steel barrel features a #3 contour, which provides stiffness for accuracy while the fluting reduces weight and increases surface area for cooling. With an optic and bipod mounted, expect a total system weight approaching 12 lbs, which is manageable for a dedicated prone or bench rifle but noteworthy for extended mountain carries.
Who is this NOT for?
This rifle is not for a first-time shooter or someone seeking a low-cost, low-recoil plinking rifle. The 28 Nosler cartridge uses significant powder charges, generating substantial muzzle blast, recoil, and barrel heat, with barrel life typically around 1,200-1,500 rounds before accuracy degrades. It's also not ideal for dense woods hunting, where its length and weight are a hindrance; a compact rifle like the Stevens 334 in .308 Win is better suited for that environment.
What's in the box?
You receive the barreled action bedded into the hand-laid Monte Carlo fiberglass stock, the Accubrake ST muzzle device threaded and installed, and one internal box magazine. The box magazine provides a capacity of 3+1 rounds, which is standard for magnum cartridges of this length. Weatherby does not include scope bases, rings, or a case, so factor in an additional $150-$300 for a proper mounting system and a hard case suitable for a 46.25-inch rifle.
Is the Weatherby Mark V Accumark worth it at $2025.99?
Yes, but only if your shooting discipline demands its specific long-range ballistic capability. At this price, you are paying for the Mark V's renowned nine-lug action strength, the premium TriggerTech trigger with a user-adjustable pull weight down to 1.5 lbs, and the factory bedding of the barrel and action into a rigid composite stock. If your needs are for general big-game hunting under 600 yards, a more affordable and milder-recoiling option like the Stevens 334 in .243 Win represents a far better value.

Pros & cons
What works
- Threaded 26-inch fluted barrel ready for suppressor or brake — reduces felt recoil by an estimated 40% with the Accubrake ST installed.
- TriggerTech trigger is user-adjustable from 1.5 to 4 lbs — provides a consistent, crisp 2.5 lb break out of the box.
- Composite stock is fully bedded to the action — enhances rigidity for consistent sub-MOA accuracy potential.
- Mark V nine-lug action handles 28 Nosler pressure safely — rated for sustained pressures exceeding 65,000 PSI.
Trade-offs
- 28 Nosler barrel life is limited — expect throat erosion requiring rebarreling after 1,200-1,500 rounds.
- Ammunition cost is high — factory 28 Nosler ammo averages $85-$110 per box of 20 rounds.
- No scope mounting hardware included — adds $150-$300 and installation time before the rifle is range-ready.
- Substantial muzzle blast and recoil — not suitable for prolonged range sessions or inexperienced shooters.

Frequently asked questions
- Is the barrel threaded for a suppressor?
- Yes, the 26-inch stainless barrel is threaded 5/8-24 at the muzzle, which is the standard pitch for .30 caliber and larger suppressors. This allows direct mounting of a muzzle brake, compensator, or a compatible sound suppressor. You must ensure your chosen muzzle device or suppressor is rated for the high pressure and muzzle energy of the 28 Nosler cartridge.
- Does it come with a scope mount installed?
- No, the rifle does not come with scope bases or rings installed. The receiver is drilled and tapped for standard Remington 700 pattern bases, which are widely available from manufacturers like Nightforce, Warne, or Talley. Plan for a lead time of 3-5 business days to receive and install proper bases and rings before your first range trip.
- What is the barrel life of the 28 Nosler?
- Expect a practical accuracy barrel life of approximately 1,200 to 1,500 rounds with normal use. This is due to the high operational pressures (around 65,000 PSI) and large powder charges (85+ grains) that erode the throat rapidly. This is a significant cost factor, as a replacement barrel and gunsmithing will cost $800-$1,200.
- Can I use .280 Remington ammunition in this rifle?
- Absolutely not. The 28 Nosler and .280 Remington are completely different cartridges with different dimensions and vastly different pressures. Attempting to chamber a .280 Remington round in a 28 Nosler rifle is dangerous and will cause a catastrophic failure. Only use ammunition clearly marked as 28 Nosler.
