Wby Ammo 257wby 115gr Nos 20/200

The Weatherby Ammo 257 WBY Magnum with 115-grain Nosler Ballistic Tip ammunition delivers the velocity and accuracy that defined Roy Weatherby's magnum legacy since the 1940s. This is ultra-high velocity ammunition engineered for long-range precision, hitting 3,400 feet per second—a velocity tier that distinguishes the .257 WBY Magnum as a flat-shooting, hard-hitting round suitable for medium to large game at extended distances.

The 115-grain Nosler Ballistic Tip projectile combines a streamlined polymer tip for flight stability with a bonded copper-jacketed construction for controlled expansion on impact. At 3,400 fps, this cartridge generates significant downrange energy and minimal bullet drop, characteristics that make it effective beyond typical hunting ranges. The ballistic coefficient and aerodynamic profile of the Nosler round mean flatter trajectories and less wind deflection—critical factors for precision shooting at distance. This ammunition is factory-loaded to Weatherby specifications and packaged in 20-round boxes for reliable performance.

Shooters pursuing medium to large game across open terrain—mule deer, elk, and similar species at 300+ yards—benefit from the .257 WBY Magnum's velocity advantage and energy retention. Long-range rifle hunters and competitive marksmen using Weatherby rifles or other .257 WBY-chambered platforms depend on this class of ammunition for consistent, accurate performance. The cartridge's flatter trajectory reduces holdover calculations, a practical advantage in field conditions where precise aiming is critical and second shots may be limited.

The .257 WBY Magnum occupies a niche between standard .25 caliber cartridges and larger magnums, offering hunters a high-velocity option that balances power with manageable recoil in a medium-frame rifle. Weatherby's ammunition continues the brand's commitment to the fast, flat-shooting loads that established its reputation in the custom ammunition market.
