Description
The .338 Weatherby RPM was built to solve a real problem: hunters wanted .33 caliber knockdown power without hauling a nine pound magnum rifle up a ridge. Weatherby's answer puts that cartridge in the slimmer six lug Mark V action, and the Accumark is the classic platform to carry it. At 7.2 pounds unloaded with a 46.25 inch overall length, this is a rifle you can pack all day and still trust when a bull elk or big bear steps out at distance.
What Makes the Accumark Tick
The fluted #3 contour barrel runs 24 inches and comes threaded with Weatherby's Accubrake ST installed, which takes a lot of the sting out of a cartridge this stout. Underneath sits the hand-laid Monte Carlo fiberglass stock with aluminum bedding blocks, the same recipe that has kept the Accumark near the top of Weatherby's lineup for decades. A TriggerTech trigger breaks clean and consistent, and the whole rifle wears Graphite Black Cerakote over the receiver, bolt, and safety, with the two-toned fluted stainless barrel giving it that unmistakable Accumark look. Owners consistently report tight groups from this platform, and Weatherby backs it with their sub-MOA guarantee using premium factory ammo.
Feeding and Setting Up the .338 RPM
Capacity is 4+1, which is generous for a magnum class hunting rifle, and the two-position safety is simple to run with gloves on. The receiver ships without sights and is drilled and tapped, so plan on a quality scope and six lug Mark V bases. Push 225 grain bullets at serious velocity and you have a legitimate elk, moose, and bear rifle that still shoots flat enough for open country work.
A Mark V Accumark Worth the Name
Weatherby has been refining this rifle since the 1990s, and the RPM chambering might be the most practical version yet. Light enough to carry, accurate enough to stretch out, and chambered for one of the smartest cartridges Weatherby has released in years.

Frequently Asked Questions
What is the .338 Weatherby RPM cartridge good for?
The .338 RPM delivers .33 caliber magnum performance from Weatherby's smaller six lug action, so you get big game stopping power in a lighter, trimmer rifle. It pushes heavy bullets fast enough for elk, moose, and large bears while still shooting flat for longer cross-canyon work. Think of it as serious punch without the bulk of a full size magnum.
Does the Mark V Accumark come with a muzzle brake?
Yes, this model ships with Weatherby's Accubrake ST installed on the threaded 24 inch barrel. It does a noticeable job taming recoil on a cartridge this powerful, and you can remove it if you prefer a cleaner muzzle or want to run a different device.
Is the Weatherby Accumark accurate enough for long range hunting?
That is exactly what it was built for. The fluted #3 contour barrel, aluminum bedding blocks in the hand-laid fiberglass stock, and crisp TriggerTech trigger all work together for repeatable precision, and Weatherby backs the rifle with a sub-MOA guarantee using qualifying premium factory ammunition. Plenty of Accumark owners report groups well under an inch at 100 yards.
Does this rifle come with a scope or sights?
No, it ships without sights. The receiver is drilled and tapped, so grab bases made for the six lug Mark V action and pair it with a quality scope. Given what this cartridge can do at distance, it deserves good glass.
