About this product
What is the Weatherby Mark V Accumark LH 6.5×300 Weatherby Mag? This left-hand bolt-action rifle is a specialized long-range platform built for shooters who need uncompromising precision and field durability. Chambered in the high-velocity 6.5×300 Weatherby Magnum and featuring a 26-inch fluted stainless barrel, it's designed to maintain accuracy under demanding conditions where standard hunting rifles would struggle. The combination of a hand-laid fiberglass stock and Cerakote finish ensures this rifle can handle rough terrain while delivering consistent sub-MOA performance.
What is the Weatherby Mark V Accumark used for?
The Weatherby Mark V Accumark is built for extreme long-range hunting and precision shooting applications where wind deflection and bullet drop become critical factors. With its 26-inch barrel optimized for the 6.5×300 Weatherby Magnum cartridge, this rifle generates muzzle velocities exceeding 3,400 fps with 140-grain projectiles, making it effective out to 1,200 yards on large game. The left-hand configuration gives southpaw shooters proper ergonomics without compromising the rifle's 8.3-pound balanced weight distribution.
How does the Weatherby Mark V Accumark compare to the Stevens 334?
The Weatherby Mark V Accumark outperforms the Stevens 334 in both precision engineering and long-range ballistics, but at nearly three times the price point. Where the Stevens 334 in .308 Win provides basic reliability at 200-300 yard ranges, the Weatherby's 6.5×300 Weatherby Magnum cartridge maintains supersonic velocity past 1,500 yards with significantly flatter trajectory. The Accumark's TriggerTech trigger breaks at a consistent 2.5 pounds versus the Stevens' 4-6 pound factory pull, giving experienced shooters better control for precision shots.
What does it weigh and what are the dimensions?
The rifle weighs 8.3 pounds with an overall length of 48.25 inches, making it 4.5 inches longer than most hunting rifles due to its specialized 26-inch barrel. The #3 contour barrel features 8 longitudinal flutes that reduce weight by approximately 12 ounces while maintaining stiffness for consistent harmonics. At 48.25 inches overall, this rifle requires careful consideration for transport in standard 42-inch hard cases, though the design balances well for off-hand shooting positions.
Who is this NOT for?
This rifle is not for casual plinkers or budget-conscious hunters who don't need its specialized long-range capabilities. The 6.5×300 Weatherby Magnum ammunition costs approximately $85-120 per box of 20 rounds, making practice sessions significantly more expensive than with common calibers like the .308 Winchester found in our Stevens 334. The left-hand configuration also makes this specific model unsuitable for right-handed shooters unless they're willing to adapt to unconventional operation.
What's in the box?
The rifle ships with the Accubrake ST muzzle brake pre-installed, one 3-round detachable magazine, and standard Weaver-style base mounts for optics installation. Unlike many factory rifles, it does not include scope rings or a basic optic, requiring an additional $300-800 investment for a suitable long-range scope. The trigger comes preset from the factory at 2.5 pounds with minimal creep, though it's adjustable down to 1.5 pounds for competitive shooters.
Is the Weatherby Mark V Accumark worth it at $2,199?
At $2,199, this rifle justifies its price for serious long-range hunters and competitive shooters who need left-hand operation and extreme ballistics. The combination of Weatherby's nine-lug action, custom TriggerTech trigger, and specialized barrel contour provides performance that would cost $3,500+ in a custom build. For hunters who regularly engage game beyond 500 yards or compete in PRS-style matches, the investment pays dividends in first-round hits and consistent grouping under 0.75 MOA.

Frequently asked questions
- Is it compatible with standard 6.5 Creedmoor ammunition?
- No, this rifle is chambered specifically for 6.5×300 Weatherby Magnum, which is a proprietary cartridge with different dimensions and pressure specifications. Attempting to fire 6.5 Creedmoor ammunition could cause dangerous malfunctions. Weatherby-produced ammunition or custom handloads using Weatherby-specific data are required for safe operation.
- Does it come with a thread protector for the muzzle brake?
- The Accubrake ST muzzle brake is permanently installed and not designed for removal, so no thread protector is included. The 5/8×24 threads are intended for suppressor mounting only, requiring ATF Form 4 approval for legal use. For hunters in states restricting muzzle devices, this configuration may not be compliant without modification.
- How long does shipping take for firearms?
- Firearm shipments typically take 3-7 business days after the 3-day mandatory waiting period and FFL verification. All firearms ship via UPS or FedEx with adult signature requirement and must be sent to a licensed FFL dealer for transfer. Expedited shipping is available for an additional $45, reducing transit time to 2 business days.
- Can I return it if it doesn't fit my needs?
- Firearms may be returned within 30 days only if unfired and in original packaging, subject to a 15% restocking fee. Once the firearm has been fired or the serial number registered to an owner, returns are not accepted due to federal regulations. We recommend consulting with our experts or reviewing our <a href="/blog/long-range-rifle-selection/">long-range rifle selection guide</a> before purchase.
- Does this work with aftermarket chassis systems?
- The Mark V action has unique dimensions that limit compatibility with most aftermarket chassis systems. Only chassis specifically designed for Weatherby Mark V long actions will fit properly, such as offerings from MDT or Manners. The factory fiberglass stock provides excellent stability, but aftermarket options typically add 2-3 pounds to the overall weight.
