Description
The .240 Weatherby Magnum was Roy Weatherby's last cartridge design, and it still holds the title of the fastest commercially loaded 6mm you can buy. Pushing 100 grain bullets past 3,200 fps with a trajectory flat enough to make range estimation almost an afterthought, it is a deer and antelope cartridge that punches well above its bore size. The Mark V Apex gives that classic speed demon a thoroughly modern home, and at 6.5 pounds bare, it is the kind of rifle you stop noticing on your shoulder about a mile into the hike.
What Makes the Mark V Apex Different
The Apex is built on Weatherby's proven Mark V steel action with the short 54 degree bolt throw that keeps your hand clear of the scope and cycles fast when a second shot matters. The 24 inch fluted barrel wears a two-tone Cerakote finish in Coyote Tan and Graphite Black, and the muzzle is threaded 5/8×24 with Weatherby's Accubrake ST installed. That brake uses 30 symmetrical ports blended to match the barrel profile, and it takes real bite out of recoil. A TriggerTech trigger handles fire control with the crisp, clean break that brand is known for. Since January 2024, Weatherby spins the .240 barrels at a 1:7.5 twist, so heavier, higher BC bullets stabilize just fine.
The Apex Carbon Fiber Advantage
A big chunk of the weight savings comes from the Peak 44 Bastion stock, one of the lightest production vertical grip carbon fiber stocks made at just 23 ounces. It has an ambidextrous palm swell, a generous thumb groove, and dual sling studs up front so you can run a bipod and sling at the same time. Out back, the 3DHEX recoil pad uses a 3D printed lattice that collapses progressively under recoil, stretching out the impulse so the rifle shoves instead of snaps. Between the pad, the brake, and the mild-mannered .240, this one is genuinely pleasant to shoot. Add a quality scope and you have a flat-shooting mountain rig that is ready for opening day.

Frequently Asked Questions
Does the Weatherby Mark V Apex come with sights or a scope?
No, it ships without sights. The receiver is drilled and tapped for scope mounts, so plan on adding bases or a rail plus rings and glass. Given how flat the .240 Weatherby Magnum shoots, a quality variable in the 3-15x or 4-16x range is a natural match.
What is the .240 Weatherby Magnum good for?
It is the fastest factory-loaded 6mm cartridge out there, driving 100 grain bullets around 3,200 fps. That makes it a superb deer and antelope round with a very flat trajectory, and lighter bullets handle varmint duty well too. Recoil is mild compared to Weatherby's bigger magnums, especially with the Accubrake and 3DHEX pad on this rifle.
Can I remove the muzzle brake on the Mark V Apex and run a suppressor?
Yes. The Accubrake ST threads onto a standard 5/8×24 muzzle, so it comes off easily and most common suppressors or other muzzle devices will thread right on. Just keep in mind your point of impact can shift when you swap devices, so reconfirm zero.
Will the Mark V Apex stabilize heavier .240 bullets?
It should. Weatherby updated the .240 Wby Mag barrels to a faster 1:7.5 twist at the start of 2024, a big jump from the old 1:10. That opens the door to heavier, high BC 6mm bullets that hold velocity better at longer distances.
