Description

There are magnum rifles, and then there's a Mark V chambered in .338-378 Weatherby Magnum. This cartridge takes the massive .378 Wby case and necks it to .338, pushing heavy bullets at speeds that keep them flat and carrying serious energy way out past where most hunting rounds run out of steam. It was built for big animals at long distances, think elk across a canyon or moose and big bears where you want authority on the first shot. The Accumark is the platform Weatherby designed to get the most out of it.

What Makes the Mark V Accumark Tick

The heart of the rifle is the Mark V action, a 9-lug design with a short 54 degree bolt lift that cycles fast and clears low-mounted scopes with room to spare. The 26 inch #3 contour barrel is fluted stainless with a two-tone finish, and it wears Weatherby's Accubrake ST on 5/8×24 threads to tame recoil, something you will appreciate with this chambering. A TriggerTech Field trigger breaks clean with zero creep, and the whole package carries Weatherby's Sub-MOA guarantee: a three-shot group under an inch at 100 yards from a cold barrel with quality ammo. The hand-laid Monte Carlo fiberglass stock has a matte gel coat with spiderweb accents and won't shift your zero when the weather turns ugly.

Living With the Accumark in .338-378

At 8.3 pounds bare and 48.25 inches overall, this is not a featherweight mountain rifle, and that's by design. The extra heft settles the rifle for deliberate shots and helps soak up the recoil from a cartridge in this class. Capacity is 2+1 through a hinged floorplate, plenty for a hunting rifle where the first round matters most. The receiver comes drilled and tapped with no sights, so plan on a quality scope with generous eye relief. The graphite black Cerakote metalwork shrugs off rain, snow, and hard miles in the truck or on horseback. If your hunts happen where the shots get long and the animals get big, this is one of the most proven ways to be ready for them.

Frequently Asked Questions

Does the Mark V Accumark come with any accuracy guarantee?

Yes. Every Mark V rifle carries Weatherby's Sub-MOA guarantee, meaning it will print a three-shot group of .99 inches or less at 100 yards from a cold barrel when fed Weatherby factory or premium ammunition. That is a factory-backed promise, not marketing talk, and the fluted stainless barrel and aluminum bedding blocks in the stock are a big part of why they can make it.

How bad is the recoil on the .338-378 Weatherby Magnum?

It is a stout cartridge, no way around it, but this rifle is set up to manage it well. The included Accubrake ST knocks felt recoil down substantially, and the 8.3 pound weight plus the raised Monte Carlo comb keep it controllable from field positions. Double up on ear protection at the range, because that brake makes it loud for anyone standing nearby.

Does the Weatherby Mark V Accumark come with sights or a scope?

No, it ships without sights, and the receiver is drilled and tapped for scope mounts. Given what this cartridge can do at distance, pair it with a quality scope, and pick one with generous eye relief since magnum recoil and short eye relief do not mix well.

What is the .338-378 Wby Mag best suited for?

This is a true long-range big game cartridge, built by necking the huge .378 Weatherby case down to .338 caliber. It drives heavy 225 to 250 grain bullets fast enough to stay flat and hit hard at ranges where most cartridges have faded, making it a favorite for elk, moose, and large bears. It is more rifle than you need for deer, but for big-bodied game at long distance it shines.
