The Weatherby Mark V Weathermark LT is a bolt-action rifle chambered in 6.5-300 Weatherby Magnum. The "LT" designation indicates a lighter build, achieved through a fluted barrel and composite stock. At 9 lbs with a 28-inch barrel, it is on the heavier end for a lightweight rifle, but the 6.5-300 Wby Mag generates significant recoil and the weight helps manage it.

Detailed Features 

 
The fluted barrel reduces weight somewhat and helps dissipate heat during extended shooting sessions. The Accubrake ST muzzle brake makes a meaningful difference with this cartridge, reducing felt recoil enough that follow-up shots are manageable. The TriggerTech Field trigger is adjustable and has a clean break with minimal creep. Cerakote Flat Dark Earth on the barrel and receiver resists corrosion and wear in the field. The sub-MOA accuracy guarantee is a Weatherby standard for the Mark V line. 
 

Usage Scenarios 

• Long-Range Hunting: The 6.5-300 Wby Mag with a 28-inch barrel and 1:8" twist produces a flat trajectory suited to elk, mule deer, and other large game at extended distances. 
• Precision Shooting: Sub-MOA guarantee and adjustable TriggerTech trigger work well for long-range target work. 
• Field Use: Cerakote finish and composite stock hold up to weather without the maintenance requirements of traditional blued steel.

The Weatherby Mark V Weathermark LT in 6.5-300 Wby Mag draws consistent praise for accuracy and build quality. The FDE Cerakote finish and overall fit are frequently mentioned as highlights. Long-range performance is the most common strength cited. The 6.5-300 Wby Mag's flat trajectory makes it effective on big game at distances where most cartridges start dropping significantly.

The LT designation is valued by hunters who carry long distances, though at 9 lbs some note it is not as light as they expected. Recoil management is generally described as good given the cartridge's power, with the Accubrake ST getting credit for that.

Price is the most consistent criticism. The Mark V line commands a premium, and some buyers question whether the cost is justified compared to less expensive precision bolt-actions. Customer service feedback is mixed. Some owners report positive warranty and support experiences, others less so. Customization discussion is common, particularly around optic choices for the caliber's effective range.
