Rifles and Ammunition

Weatherby continues to chamber the .257 Weatherby Magnum in several models based on both the Mark V and Vanguard action types. The Weatherby Custom Shop offers a more personalized rifle based on these actions. Remington Arms manufactures released the Special Editions of the Model 700 CDL SF and the Model 700 LSS in 2008. They have continued to offer the Model 700 CDL SF in the .257 Weatherby. The Weatherby rifles have deeply blued barrels while the Remington rifles have matte stainless steel barrels.

Conley Precision Cartridge Company manufactures several premium lines of .257 Weatherby ammunition using Barnes, Nosler, Speer, Swift and Trophy Bonded bullets.

The 120 gr (7.8 g) Weatherby N257120PT ammunition should not be used in older .257 Weatherby rifles as the twist rate is too slow to adequately stabilize the bullet. The 117 gr (7.6 g) Weatherby H257117RN ammunition is manufactured for riles with the slower twist rate.
