Specs at a glance
About this product
If you're looking for a rifle that's built to reach out and touch something at distances most shooters only dream about, let me tell you about the Weatherby Mark V Accumark .300 Weatherby Magnum in Graphite Black. I've had the pleasure of handling this exact model at the shop, and it's the kind of precision tool that makes you want to find a longer range. It's built on the legendary Mark V action, which is one of the strongest and smoothest bolt actions ever made. The .300 Weatherby Magnum chambering is a flat-shooting powerhouse, and this Accumark package comes loaded with features that make it ready for long-range hunting or target work right out of the box.

Key Features
- Fluted #3 Contour Barrel – Reduces weight and helps dissipate heat faster, meaning you can shoot more rounds before the barrel starts walking. This keeps your groups tighter when it counts.
- TriggerTech Field Trigger – A crisp, adjustable trigger that breaks clean and lets you focus on the shot, not the pull. It's a huge upgrade over standard factory triggers.
- Accubrake Muzzle Brake – Cuts felt recoil significantly, so you can spot your own hits and stay on target for follow-up shots. Makes the .300 Wby Mag a lot more pleasant to shoot.
- Forged One-Piece Bolt with Low Bolt Rotation – The Mark V action cycles fast and smooth, with only a 54-degree bolt lift. That quick throw means you can work the bolt without breaking your cheek weld.
- Drilled-and-Tapped Receiver – Ready for optics right away. No gunsmithing needed to mount your favorite scope, which saves you time and money.
Who It's For
This rifle is for the shooter who wants a dedicated long-range hunting or precision target rifle that's ready to go from the factory. If you're after elk, mule deer, or similar big game at extended distances, the .300 Weatherby Magnum is a proven performer. It's also a great choice for the target shooter who wants to compete in long-range matches or just enjoys ringing steel at 800+ yards. The Accumark is not a budget rifle, but it's a serious tool for serious shooters.
Pros & Cons
- Pros: Extremely accurate out of the box; smooth, reliable action; effective muzzle brake; high-quality trigger; durable stock.
- Cons: It's a heavy rifle at around 8.5 lbs. unloaded, which can be a lot to carry on a long mountain hunt. Also, .300 Weatherby Magnum ammunition is not cheap, and recoil is still stout even with the brake.
