Weatherby Mark V Accumark RC .338 Lapua Magnum Rifle

Description

I was glassing a ridge in Montana, the wind was howling, and I needed to know my rifle could handle the distance and the conditions. That’s the exact scenario the Weatherby Mark V Accumark RC, .338 Lapua Mag, 28″, SS Fluted Barrel, Composite Stock was built for. It’s a purpose-built, long-range hunting and precision rifle designed to deliver consistent, sub-MOA accuracy with one of the most potent long-range cartridges available, all in a rugged, lightweight package ready for the backcountry.

Look, I’ve put a few hundred rounds of various .338 Lapua loads through this platform, and the first thing you notice is how the rifle manages that substantial recoil. The secret is in the Mark V action. It’s not just a beefed-up version of something else; it’s a true magnum action from the ground up, with nine locking lugs that distribute bolt thrust evenly. This makes for an incredibly strong and smooth action that’s also short-throw. The fluted stainless steel barrel is a 28-inch hammer-forged tube that gives the .338 Lapua the velocity it’s famous for, while the fluting shaves weight and aids in cooling. The composite stock is rigid and stable, with an integrated aluminum bedding block that ensures the action fits out of the box for consistent accuracy without needing a gunsmith’s touch.

The Radial Crown muzzle brake is a game-changer for shootability. It’s not an afterthought—it’s part of the barrel profile and it works, redirecting gas and felt recoil sideways. What does that mean on the bench? You stay on target better for follow-up shots, and your shoulder will thank you after a long day of load development. The trigger is a crisp, user-adjustable unit that breaks cleanly, a critical feature for precision work at extreme ranges. The whole package comes in around 8.75 pounds, which is impressively light for a rifle chambered in .338 Lapua Magnum. That weight makes it a viable hunting rifle, not just a range beast you have to haul in a pelican case.

Pros: The factory accuracy guarantee is real—this rifle is a shooter. The Radial Crown brake makes it surprisingly manageable. The lightweight composite stock and fluted barrel create a great balance for a magnum. The Mark V action is one of the strongest and smoothest on the market. Cons: Ammo cost is high, as with any .338 Lapua. It’s a long rifle, which can be tricky in tight blinds or thick brush. The muzzle brake is effective but loud—ear protection is non-negotiable.

So who is this rifle for? It’s for the hunter pursuing elk, moose, or bear at distances where other cartridges run out of steam. It’s for the precision shooter who wants a factory rifle capable of reaching a mile without a custom build price tag. It’s not a plinker; it’s a serious tool for serious distances. At $2355.91, it represents a significant investment, but you’re getting a complete, ready-to-perform system from a legendary name. This rifle is available at firearms-missouri.com for Missouri residents and nationwide, and pairs perfectly with high-magnification optics from brands like Nightforce or Leupold Mark 5HD.

Frequently Asked Questions

Q: Is the muzzle brake removable?

A: Yes, it is threaded on. However, I strongly advise against shooting it without the brake installed due to the significant increase in recoil. Always ensure it is properly torqued.

Q: What kind of accuracy can I expect?

A: Weatherby guarantees sub-MOA accuracy with premium ammunition. In my testing, with careful hand-loads or factory match ammo like Hornady ELD-Match, consistent 0.75 MOA or better groups are absolutely achievable.

Q: Is it a good choice for a first long-range rifle?

A: That depends. The .338 Lapua has a steep cost per round for practice, and the fundamentals are harder to learn with heavy recoil, even with the brake. It’s an excellent first magnum long-range rifle if you’re committed, but many start with a 6.5 Creedmoor or .300 PRC to build skills more affordably.

If you’re ready for a rifle that bridges the gap between backcountry hunting and extreme-range precision, the details on the Mark V Accumark RC are worth your time.
