The Weatherby Mark V Backcountry 2.0 Ti is a bolt-action rifle built around weight reduction without giving up caliber performance. At 4.9 lbs with a titanium receiver and carbon fiber stock, it is one of the lightest production bolt guns in the .240 WBY Mag chambering. This is a left-hand configuration.

Detailed Features 

• The titanium receiver and carbon fiber stock bring the rifle to 4.9 lbs, which is the main engineering story here. That weight comes up every time you climb a mountain. 
• The 24-inch barrel with a 1:10" twist rate handles the .240 WBY Mag well across the bullet weights most hunters run in that cartridge. 
• The Accubrake ST muzzle brake reduces felt recoil noticeably, which matters more on a 4.9 lb rifle than on a heavier one where mass absorbs some of the impulse. 
• Drilled and tapped mounts let you add a scope without proprietary hardware. 
   

Usage 

This rifle is suited to backcountry hunting where pack weight is a real constraint. The .240 WBY Mag is flat-shooting and effective on medium to large game at distance. Left-handed hunters in particular have few options this light in a quality production rifle, and the Mark V action is a known quantity.

Owners of the Mark V Backcountry 2.0 Ti LH in .240 WBY Mag tend to focus the conversation on two things: how light it is and how well it still shoots given that weight.

The 4.9 lb figure gets real appreciation from hunters who carry rifles over serious terrain. Several reviewers mention that it changed how they thought about all-day mountain hunts. The .240 Weatherby Magnum cartridge is seen as a good fit for the platform, with the flat trajectory working well on longer shots in open country.

The Accubrake ST gets credit for making recoil manageable on a rifle this light. Without it, a 4.9 lb rifle in a magnum chambering would be noticeably punishing, and most owners feel Weatherby got the balance right.

The price is the consistent hesitation point, with some potential buyers comparing it to heavier alternatives that cost less. Left-handed shooters are generally more forgiving on price because the LH options at this weight class are so limited. Build quality and materials are rarely questioned, but the cost-to-value calculation depends heavily on how much the weight reduction is worth to the individual.
