The Weatherby Mark V Backcountry Ti 2.0 is a bolt-action rifle chambered in 6.5 WBY RPM, built for hunters who count every ounce on multi-day backcountry trips. The titanium receiver is the main driver behind the 4.9 lb weight. A titanium action is significantly lighter than steel at comparable strength. Paired with a carbon fiber stock and a 24-inch barrel, it handles the physical demands of long approaches into remote terrain.

Detailed Features 

• Lightweight Titanium Receiver: Reduces overall weight while retaining the strength needed for the 6.5 WBY RPM cartridge's higher operating pressures. 
• Accubrake ST Muzzle Brake: Cuts felt recoil, which matters at 4.9 lbs. A lightweight rifle in a hot cartridge needs brake mitigation or follow-up shots become uncomfortable. 
• Carbon Fiber Stock: Handles weather and rough use without adding weight. The stock contributes both to the low overall weight and to consistent bedding under varying conditions. 
• Drilled & Tapped Sights Base: Ready for scope rings without additional machining.

The Mark V Backcountry Ti 2.0 LH in 6.5 WBY RPM draws consistent praise from hunters who prioritize keeping pack weight down. The titanium receiver is the key spec. At 4.9 lbs, this is one of the lightest full-power hunting rifles available, and owners who've carried it all day in the mountains appreciate that.

Accuracy is frequently cited as a strong point. Buyers report shooting well right out of the box, and the 6.5 WBY RPM cartridge, a proprietary rebated-rim cartridge pushing 6.5mm bullets faster than the 6.5 Creedmoor, gets credit for its long-range performance on elk and similar game.

The price generates debate. Weatherby's titanium-actioned rifles are expensive, and some buyers question whether the weight savings over a comparably accurate steel-actioned rifle justify the cost difference. Opinions split roughly along how seriously someone weights (literally) every pound on a backpack hunt.

Recoil is a recurring discussion point. At 4.9 lbs, the rifle is light enough that even with the Accubrake ST, the 6.5 WBY RPM produces noticeable recoil. A few shooters find it uncomfortable for extended range sessions, though most hunting-oriented users consider it acceptable for the field use case.

Ammo availability draws real concern. 6.5 WBY RPM is a proprietary Weatherby cartridge, so it's not stocked as widely as .308 or 6.5 Creedmoor. Cost per round is also higher. For a rifle you plan to shoot a lot on the range, that adds up. Ergonomics and fit are reported as good by most, though stock feel is personal and some shooters prefer different grip geometry.
