Weatherby Mark V Frontier .375 H&H 24-inch Threaded
Pros & cons
What works
- Suppressor-ready 5/8x24 threaded muzzle—eliminates costly gunsmithing for NFA accessory attachment
- 8.70 lb weight (3945g) manages .375 H&H recoil effectively, roughly 30% less felt kick than a 7-lb rifle
- Adjustable TriggerTech trigger with a 2.5-4.5 lb pull range for a crisp, tunable break
- Hand-finished exhibition walnut stock provides superior rigidity and moisture resistance over cheap laminates
Trade-offs
- No detachable magazine—reloading requires feeding rounds individually through the ejection port
- High bore axis of Monte Carlo stock can complicate obtaining a consistent cheek weld with low-mounted optics
- Cerakote finish on barrel only; receiver is blued steel, creating a two-tone appearance some find less cohesive
- At 44.25 inches long, it will not fit in most standard 42-inch airline rifle cases without disassembly

About this product
The Weatherby Mark V Frontier .375 H&H 24-inch Threaded is a premium, suppressor-ready big-game rifle engineered for precision shooting with heavy magnum cartridges in demanding field conditions. It represents the intersection of classic Weatherby Mark V reliability with modern threaded-barrel practicality, built specifically for hunters who need regulated accessories in unforgiving environments. This rifle's core engineering addresses the significant recoil management and mounting system requirements that define the .375 H&H Magnum cartridge's utility.
What is the Weatherby Mark V Frontier .375 H&H used for?
This rifle is engineered for controlled, repeatable shots on dangerous game at ranges out to approximately 250 yards. The .375 H&H Magnum cartridge generates over 4,500 foot-pounds of muzzle energy, making it a legal minimum for species like Cape buffalo in many African countries, and a responsible maximum for large North American species like grizzly or moose. The 24-inch threaded barrel and integrated Accubrake ST allow for direct suppressor attachment to reduce muzzle blast, a critical consideration for follow-up shots and hearing preservation in thick brush. You are buying a tool built for one purpose: delivering a single, massive projectile on target with mechanical certainty when the consequences of a miss or poor hit are severe.
How does the Mark V Frontier compare to the Stevens 334 Rifle?
The Mark V Frontier is fundamentally engineered for a different class of cartridge and application than the budget-oriented Stevens 334 series. Where the Stevens 334 in .308 Win is a capable, 7.5-pound rifle for general-purpose hunting at moderate ranges, the Mark V Frontier is a purpose-built dangerous game platform. Its 1:10” twist barrel stabilizes heavy 300-grain bullets, its 9-lug bolt head handles over 62,000 PSI of chamber pressure, and its overall weight of 8.70 lbs is a deliberate feature for managing over 35 ft-lbs of free recoil. The Stevens 334 is better for casual deer hunting; the Mark V Frontier is necessary for stopping a charging animal where shot placement and immediate second-shot capability are non-negotiable.
What does it weigh and what are the dimensions?
Unloaded, the rifle weighs 8.70 pounds (3945 grams) and measures 44.25 inches in overall length, with a 24-inch barrel. That barrel features a 5/8x24 TPI threading pattern, the most common standard for .30-caliber and larger suppressors, allowing direct attachment of muzzle devices without adapters. The exhibition-grade walnut Monte Carlo stock adds significant mass compared to synthetic options like those on the Stevens 334 Rifle, but this weight directly translates to felt recoil reduction—this rifle will kick substantially less than a lighter 7.5-pound .375 built on a Remington 700 action.
Who is this NOT for?
This is not a rifle for a novice shooter, a budget-conscious hunter targeting whitetail deer, or anyone unwilling to navigate Title II/NFA paperwork for a suppressor. The .375 H&H Magnum round costs approximately $6 per cartridge for basic soft-points, making practice prohibitively expensive for casual use. Furthermore, the rifle's 8.70-pound weight and 44.25-inch length make it cumbersome for stalking in dense timber or carrying for extended periods without a sling. If your primary use case involves shots inside 150 yards on non-dangerous game, a lighter rifle in .30-06 or .300 Win Mag will be more practical and economical.
What's in the box?
You receive the barreled action seated in the exhibition walnut stock, with the Accubrake ST muzzle device pre-installed on the threaded muzzle. Weatherby includes a set of 1-inch scope ring bases tapped for the standard 8-40 screws on the drilled-and-tapped receiver, along with a manual and warranty card. Notably, the box does NOT include a removable box magazine; the rifle employs a fixed, hinged floorplate magazine with a 3+1 capacity. You will need to purchase a scope, rings, a sling, and a case separately, and budget for a possible 8-12 month ATF Form 4 wait if you plan to use a suppressor.
Is the Weatherby Mark V Frontier worth it at $4,649?
Justified, if your specific use case—dangerous game hunting, long-range shooting with heavy suppressors, or collecting a classic magnum action with modern features—aligns with its engineering. This price point is approximately $2,300 higher than a basic, non-threaded .375 Ruger African, paying for the Mark V's superior 54-degree bolt lift, the hand-fitted walnut stock, the Cerakote finish, and the integrated muzzle threading. For the hunter who needs a rifle that will function perfectly once, under extreme stress, with a can attached, the investment in the Mark V action's reliability and the suppressor-ready configuration is a logical one. It is an expensive solution to a very specific problem that cheaper rifles cannot solve.

Frequently asked questions
- What thread pattern is the barrel?
- The 24-inch barrel is threaded 5/8x24 TPI. This is the industry-standard thread pitch for .30-caliber and larger muzzle devices and suppressors, compatible with models from manufacturers like SilencerCo, Dead Air, and Rugged Suppressors without requiring an adapter.
- Is this rifle drilled and tapped for a scope?
- Yes. The receiver is drilled and tapped for a standard 8-40 scope base screw pattern. It comes with 1-inch ring bases installed; you will need to purchase separate bases for 30mm or 34mm tubes. The pattern is compatible with bases from Weaver, Leupold, and Nightforce.
- Does it come with a detachable magazine?
- No. It uses a fixed, hinged floorplate magazine with a 3-round internal capacity (plus one in the chamber). This is a deliberate design choice for dangerous-game rifles to eliminate magazine-related failures; reloading is done via the top of the action with the bolt open.
- What is the trigger pull weight range?
- The adjustable TriggerTech trigger can be set from approximately 2.5 pounds to 4.5 pounds. I recommend a setting no lighter than 3.5 pounds for a field rifle in this caliber to prevent accidental discharges under physical stress or in cold weather.
- Can the Accubrake ST be removed?
- Yes. It is torqued onto the 5/8x24 threads and can be removed with a standard 3/4-inch wrench, provided you first ensure the firearm is unloaded. Removal exposes the threads for direct suppressor attachment or for installing a thread protector.
- Is the stock bedded?
- The exhibition walnut stock is free-floated from the recoil lug forward, with the action secured via two bedding screws at the recoil lug and tang. It is not fully pillar-bedded or glass-bedded from the factory, which is typical for a production rifle at this price point.
