Description
Weatherby built the Mark V Backcountry Guide for hunters who count ounces before a long climb, and this 6.5 Weatherby RPM version might be the sweetest pairing in the whole lineup. The RPM cartridge was designed from the ground up to run through Weatherby's slim six-lug Mark V action, pushing a 140 grain bullet in the neighborhood of 3,000 to 3,100 fps with muzzle energy approaching 3,000 foot pounds. That's real magnum-class performance out of a rifle that weighs roughly 5.4 pounds bare, with recoil that stays civil thanks to the machined titanium Accubrake ST and the honeycomb-structured 3DHex recoil pad.
How the Backcountry Guide Sheds Weight
The 22 inch barrel is a tensioned BSF carbon fiber design, meaning a 416R stainless match-grade barrel wrapped in a carbon sleeve loaded under tension. The result is a stiff, fast-cooling tube that trims serious weight up front. The Peak 44 Blacktooth stock is one of the lightest production carbon fiber stocks made, and it comes with Spartan Precision gunsmithing adapters molded right into the forend so you can snap on a Spartan bipod or tripod without adding hardware. Each stock gets hand-painted sponge pattern accents in olive green and tan, so no two rifles look quite alike.
Mark V Guide Details That Matter in the Field
The six-lug Mark V action cycles with a short 54 degree bolt throw, leaving plenty of clearance under a scope for fast follow-ups. The externally adjustable TriggerTech trigger breaks clean and lets you dial the pull to your liking, while the two-position safety locks the bolt closed so it won't creep open in a scabbard or on your pack. Feeding comes from a 4+1 hinged floorplate magazine dressed up with a topo map pattern, and the metalwork wears a graphite black Cerakote finish that shrugs off weather. The muzzle is threaded 5/8-24, so swapping the brake for a suppressor is quick work, and the shorter barrel keeps a can from turning the rifle into a flagpole. Like every Mark V, it's backed by Weatherby's sub-MOA accuracy guarantee with factory or premium ammo, and it's proudly built in Sheridan, Wyoming.

Frequently Asked Questions
What's the difference between the Backcountry Guide and the Backcountry Guide Ti?
This standard Guide model uses a steel Mark V action, while the Ti version swaps in a titanium action to trim a few more ounces. Both share the same BSF carbon fiber barrel, Peak 44 Blacktooth stock, TriggerTech trigger, and Accubrake ST. In 6.5 RPM, the standard Guide runs about 5.4 pounds, which is already featherweight territory for a hunting rifle.
Is the 6.5 Weatherby RPM enough cartridge for elk?
It is. The RPM sends 140 grain bullets at roughly 3,000 to 3,100 fps with muzzle energy near 3,000 foot pounds, which puts it a solid step ahead of the 6.5 Creedmoor. With a well-constructed bullet and good shot placement, it handles deer, antelope, and elk at practical hunting distances.
Can I run a suppressor on the Mark V Backcountry Guide?
Yes. The 22 inch barrel is threaded 5/8-24, so you can remove the Accubrake ST and spin on most common suppressors. The Guide series was built with shorter barrels partly for this reason, so the overall package stays manageable with a can attached.
Does this rifle come with an accuracy guarantee?
Every Mark V rifle is guaranteed to shoot a 3-shot group of .99 inch or better at 100 yards from a cold barrel when fed Weatherby factory or premium ammunition. Reviews of the Backcountry Guide line consistently report groups well under that mark with quality loads.
