Weatherby 307 Adventure SD .257 Weatherby Magnum 28-inch Rifle, Blued/Walnut

The Weatherby 307 Adventure SD (brand part no. 3WASD257WR8B) is a bolt-action rifle chambered in .257 Weatherby Magnum and built by Weatherby, the very brand that created this famously flat-shooting cartridge. A 28-inch barrel is cut with a 1:10-inch twist and threaded 5/8-24 to accept a brake, giving handloaders and factory-ammo shooters alike room to push the .257 Wby Mag to its full velocity potential. The checkered walnut stock and Cerakote-finished metal combine classic Weatherby styling with practical field protection. This rifle suits hunters chasing pronghorn, deer, or sheep across country where a fast, flat cartridge earns its reputation.
