The Weatherby Mark V Frontier 300 Win Mag 24” is a factory-built precision rifle that bridges the gap between a lightweight hunting rig and a long-range shooter. Chambered in .300 Winchester Magnum, this 24”-barreled Mark V delivers the legendary Weatherby accuracy and reliability right out of the box. It’s built for the hunter who also demands sub-MOA performance at the range, without having to send the action off to a custom shop.

Key Features
- Factory-True Sub-MOA Guarantee — Weatherby test-fires every Frontier and guarantees three-shot groups under one MOA at 100 yards, so you spend time shooting, not tinkering.
- 24” #2 Contour Barrel — Balances weight savings for carrying with enough barrel length to get full velocity from .300 Win Mag loads, meaning flatter trajectories and retained energy at extended ranges.
- Fluted Bolt and Three-Lug Action — The 54-degree bolt lift gives you fast cycling and clearance for oversized scopes, with a fluted bolt body that reduces friction and keeps cycling smooth even in wet weather.
- Accubrake ST Muzzle Brake — Weatherby’s own radial brake cuts felt recoil by about 53%, letting you spot your own hits and stay on target for quick follow-up shots without flinching.
- Detachable Box Magazine (DBM) — A three-round magazine feeds from the bottom, so you can load/unload without feeding rounds through the action, which is a real help when crossing fences or switching ammo types.
Who It’s For
This rifle is for the serious hunter who also shoots long-range steel and paper. If you’re a handloader who wants a production rifle that can keep up with your best loads, the Frontier gives you a solid platform without a custom build wait. It’s also a smart pick for the shooter stepping up from a .308 Win who wants the extra reach of .300 Win Mag in a package that won’t beat you up on the bench.
Pros & Cons
- Pro: Sub-MOA guarantee from the factory, so you know what you’re getting before you buy.
- Pro: Accubrake ST makes .300 Win Mag manageable for all-day shooting.
- Pro: Under 7.5 lbs bare, light enough for mountain hunting.
- Con: The synthetic stock, while rugged, lacks the adjustability of a chassis system for shooters who want to tweak length of pull or cheek height.
