It delivers consistent sub-MOA accuracy with factory ammunition, according to Weatherby specs, and the 26-inch fluted barrel with two-tone Cerakote finish resists corrosion and heat buildup.

Key Features
- Peak 44 Bastion Carbon-Fiber Stock — Saves 1.2 lbs over a traditional laminate stock, with ambidextrous palm swells and a pronounced thumb groove for a locked-in grip under recoil.
- TriggerTech Trigger — Adjustable from 2.5 to 5.0 lbs, with zero creep and a crisp break. Why it matters: eliminates trigger pull variation that opens groups at distance.
- Accubrake ST Muzzle Brake — Redirects propellant gases to reduce felt recoil by 53%, letting you spot impacts through the scope without losing sight picture.
- Spiral-Fluted Bolt — Reduces bearing surface by 40% compared to a non-fluted bolt, promoting smooth cycling even with gloved hands or in cold conditions.
- 3DHEX Recoil Pad — Hexagonal cell structure absorbs and disperses impact energy, preventing shoulder fatigue during extended range sessions.
Who It’s For
This rifle is for the shooter who hunts at extreme ranges—elk, moose, or bear—where the .30-378 Weatherby Magnum’s 4,200+ ft-lbs of energy at 500 yards matters. It’s also for the long-range competitor who wants a production gun that holds 0.5 MOA out of the box without gunsmithing.
Pros / Cons
- Pros: Sub-MOA guarantee, 6.8 lbs total weight, adjustable trigger, effective muzzle brake, spiral-fluted bolt for smooth cycling, ambidextrous stock.
- Cons: Ammunition cost is high—expect $4-6 per round for factory loads. The .30-378 Weatherby Magnum also produces significant muzzle blast even with the brake, making ear protection mandatory.

FAQ
What is the barrel twist rate on the Weatherby Mark V Apex 30-378 Weatherby Magnum?
Per Weatherby specs, the barrel has a 1:10-inch twist rate, optimized for 180-200 grain bullets commonly used in the .30-378 Weatherby Magnum.
Does the Weatherby Mark V Apex accept standard Remington 700 scope bases?
No. The Mark V action uses a proprietary two-piece base system. Weatherby offers integral rail options, or you can use aftermarket bases specifically cut for the Mark V.
Is the Accubrake ST muzzle brake removable?
Yes. The Accubrake ST is threaded onto the barrel and can be removed with a wrench. Without the brake, the rifle will have roughly 53% more felt recoil.
What is the magazine capacity of the Mark V Apex?
The rifle uses a hinged floorplate with a 3-round internal magazine. No detachable box magazine is offered from the factory.
Can the stock be swapped for a chassis system?
Yes. The Mark V action is compatible with aftermarket chassis from manufacturers like McMillan and Manners, but you must verify inlet pattern for the Mark V—it is not the same as Remington 700.
