Description
Some rifles are built for the deer stand. This one is built for the moments when the animal on the other end can hunt you back. The Mark V Dangerous Game is Weatherby's revival of their classic DGR platform, and this version comes chambered in the 378 Weatherby Magnum, the big-bore cartridge Roy Weatherby dreamed up in 1953 after his African safaris convinced him hunters needed more horsepower. It pushes a 300 grain bullet around 2,900 feet per second, which is the kind of authority you want when the job is Cape buffalo, brown bear, or anything else with a bad attitude.
What Makes the Mark V DGR Different
The heart of this rifle is the Mark V action with its nine locking lugs and short 54 degree bolt lift. That short throw clears low-mounted scopes and lets you run the bolt fast when a follow-up shot matters most. The 24 inch spiral fluted barrel wears Graphite Black Cerakote from muzzle to receiver, and it comes threaded with Weatherby's Accubrake ST installed, which takes a real bite out of the 378's famous recoil. An adjustable TriggerTech trigger lets you dial the pull weight to your liking, and the hinged floorplate gives you an extra round on board plus quick, easy unloading in the field.
A Dangerous Game Rifle That Looks the Part
The hand-laid fiberglass Monte Carlo stock gets hand-painted webbing in tan and black over a brown base, so no two look exactly alike. The raised comb keeps your cheek weld consistent under heavy recoil, and the fiberglass shrugs off weather that would punish a walnut stock. Rugged NECG iron sights come fitted from the factory, giving you a fast, reliable aiming option up close or a backup if a scope goes down in rough country.
Like every Mark V, this rifle is backed by Weatherby's sub-MOA guarantee with factory or premium ammo. For a purpose-built stopping rifle, that level of accuracy is a genuine bonus.

Frequently Asked Questions
How bad is the recoil on the Mark V Dangerous Game in 378 Weatherby?
The 378 Weatherby is a stout cartridge, no way around it, with full-power loads generating recoil well beyond a 375 H&H. That said, this rifle ships with Weatherby's Accubrake ST installed, which knocks felt recoil down dramatically, and the raised Monte Carlo comb keeps the stock from punishing your cheek. Most folks find it very manageable with the brake on, especially from field positions.
What game is the Weatherby Mark V DGR in 378 WBY Mag suited for?
This is a true heavy game rifle. The 378 Weatherby drives 300 grain bullets around 2,900 fps, which makes it a solid choice for Cape buffalo, eland, hippo, and other large African game, along with big bears, moose, and elk here in North America. It also shoots surprisingly flat for a big bore, so it handles longer shots on plains game better than most stopping cartridges.
Can I mount a scope on the Mark V Dangerous Game, or is it iron sights only?
You get both options. The receiver is drilled and tapped for scope mounts, and the short 54 degree bolt lift is designed to clear low-mounted optics. The factory-fitted NECG iron sights stay on the rifle as a fast close-range option or a backup if your glass ever fails in the field.
Is the Mark V DGR covered by Weatherby's accuracy guarantee?
Yes. Like all Mark V rifles, it's guaranteed to shoot a three-shot group of .99 inch or less at 100 yards from a cold barrel using Weatherby factory or premium ammunition. That's impressive accuracy for a dangerous game rifle, where reliability usually takes priority over precision.
