Description
The Accumark has been Weatherby's go-to long-range hunting rifle for decades, and chambering it in .300 PRC makes a lot of sense. The cartridge was designed from the ground up for heavy, high-BC .30 caliber bullets, and the Accumark gives it a proper home: a 26 inch #3 contour stainless barrel, fluted to shave weight and threaded at the muzzle with Weatherby's Accubrake already installed. That brake matters more than you might think. A .300 PRC without one will let you know about it, but with the Accubrake doing its job, follow-up shots and long range practice sessions become a whole lot more pleasant.
The Mark V Action Behind the Accumark
Underneath it all sits the Mark V action, long regarded as one of the strongest bolt actions ever put into production. The fluted, one-piece forged bolt runs on a short 54 degree lift, which means faster cycling and plenty of clearance for big objective scopes mounted low over the bore. There are no sights on this rifle because it was never meant to wear them; the receiver is ready for the glass of your choice. A TriggerTech trigger breaks clean with zero creep, and Weatherby backs the whole package with a guarantee of a three-shot group under an inch at 100 yards using factory or premium ammo.
Built for Hard Miles in the Field
The hand-laid Monte Carlo composite stock wears a gray webbed pattern over black and shrugs off weather that would swell or warp wood. The raised comb lines your eye up naturally behind a scope, and the stock's stiffness keeps your zero honest through rough handling, temperature swings, and long days in a truck or on a pack frame. Metalwork gets Graphite Black Cerakote on the receiver with the two-tone stainless barrel finish the Accumark is known for.
Why the Accumark in .300 PRC Earns Its Spot
With 3+1 capacity, a 48.25 inch overall length, and enough barrel to wring full velocity out of the cartridge, this is a legitimate elk, moose, and open-country rifle. Top it with quality glass, find the load it likes, and it will hold up its end of the deal for a very long time.

Frequently Asked Questions
Does the Mark V Accumark .300 PRC come with sights or a scope?
No, this rifle ships without sights or optics, which is standard for a rifle built for long-range work. The receiver is set up for scope mounts, and the Mark V's short 54 degree bolt lift lets you mount your scope nice and low over the bore without the bolt handle hitting the eyepiece.
How is the recoil on a .300 PRC Accumark?
The .300 PRC is a full-power magnum-class cartridge, but the factory-installed Accubrake takes a serious bite out of the recoil. Combined with the rifle's weight and well-shaped stock, most people find it very manageable from field positions and even comfortable for extended range sessions. Just bring ear protection, because brakes trade recoil for blast.
Is the Weatherby Accumark accurate enough for long-range hunting?
Yes, Weatherby guarantees a three-shot group of .99 inch or less at 100 yards from a cold barrel when using Weatherby factory or premium ammunition. The fluted match-grade barrel, bedded composite stock, and zero-creep TriggerTech trigger are all there to support that. Paired with the flat-shooting .300 PRC, it is well suited to elk and mule deer at extended distances.
Can I run a suppressor on this rifle?
The 26 inch barrel is threaded at the muzzle, so the Accubrake can be removed to attach a suppressor or another muzzle device with matching threads. Keep in mind the barrel is already 26 inches, so adding a can makes for a long rifle overall. Many owners swap between the brake for the range and a suppressor for hunting.
