Key Features

• Mark V Action: The iconic Mark V action features a 54-degree bolt lift and nine locking lugs for ultra-strong, smooth cycling. Why it matters: This design allows for a shorter bolt throw and faster follow-up shots while handling the high-pressure .338 Lapua loads reliably.
• Accumark Composite Stock: A fully adjustable stock with a Monte Carlo comb, cheekpiece, and length-of-pull spacers. Why it matters: You can dial in the fit for consistent cheek weld and recoil management, critical for maintaining accuracy on long-range shots.
• Fluted 26″ Barrel: A heavy-contour, button-rifled barrel with longitudinal fluting reduces weight and aids cooling. Why it matters: The fluting dissipates heat faster during extended strings, minimizing barrel walk and keeping groups tight even after multiple rounds.
• Adjustable Trigger: A factory-set trigger that can be adjusted from 2.5 to 3.5 pounds without tools. Why it matters: A crisp, clean break at your preferred weight eliminates trigger pull variation, a common source of fliers at distance.
• Detachable Box Magazine: A three-round detachable magazine allows quick reloads. Why it matters: In the field or on the range, you can reload without fumbling with internal box magazines, saving time during follow-up shots.

Who It’s For

This rifle is built for the serious long-range enthusiast who values precision and reliability. It suits competitive shooters in disciplines like F-Class or PRS, as well as hunters pursuing big game at extended distances—think elk, moose, or bear. The .338 Lapua Magnum cartridge delivers flat trajectories and retained energy beyond 1,000 yards, making it ideal for shooters who demand terminal performance. Collectors will also appreciate the Mark V lineage, a design that has been refined for over 70 years.

Pros and Cons

• Pros: Sub-MOA accuracy guarantee from the factory; adjustable stock for custom fit; fluted barrel for reduced weight and heat management; proven Mark V action for reliability; available in multiple calibers for versatility.
• Cons: The stock’s length-of-pull adjustment requires tools (a hex key), which is less convenient than tool-less systems on some competitors. Additionally, the .338 Lapua ammunition is expensive and harder to find than .308 Win, so budget accordingly.

FAQ

Is the .338 Lapua Magnum suitable for hunting?

Yes, it is excellent for large game like elk, moose, and bear at long ranges. The cartridge delivers high energy and flat trajectories beyond 500 yards. However, it is overkill for smaller game and produces heavy recoil, so practice is essential.

Does the Weatherby Mark V Accumark come with iron sights?

No, this model is designed for use with a scope only. The receiver is drilled and tapped for Weatherby bases, and the barrel has no front or rear sight posts. You’ll need to mount a quality long-range scope.

What is the barrel twist rate?

Per Weatherby specs, the .338 Lapua barrel has a 1:10″ twist rate, which stabilizes bullets from 250 to 300 grains effectively. This is standard for the cartridge and ensures accuracy with most match-grade loads.

Can the trigger be adjusted for a lighter pull?

Yes, the factory trigger is adjustable from 2.5 to 3.5 pounds using a hex key. Many shooters set it to 2.5 pounds for precision work, but be cautious—too light can be unsafe for field use. Always check local regulations.

Is this rifle compatible with aftermarket stocks?

Yes, the Mark V Accumark uses a standard Remington 700-style footprint for the action screws, so many aftermarket stocks (e.g., McMillan, Bell & Carlson) can be fitted with minor inletting. However, the factory stock is already highly adjustable.
