Weatherby .257 Wby Mag 100gr Scirocco Rifle Ammo

The Weatherby .257 Wby Mag with Swift Scirocco Bullets

This is Roy Weatherby's personal favorite—a cartridge and bullet combination engineered for hunters who demand flat trajectories and reliable performance at extended ranges.

What Makes It Special

The Swift Scirocco II bullet represents the pinnacle of bonded bullet technology. Its signature black tip isn't just for looks; it's part of an advanced design that delivers:

• Progressive Jacket Taper: The pure copper jacket is carefully tapered to control expansion development across a wide velocity range—from long-range shots where velocity is diminished to close-range encounters where velocity is maximum.
• Swift Bonding Technology: The jacket and core are permanently joined, ensuring high weight retention and consistent terminal performance.
• Superior Ballistics: The sleek profile and advanced secant ogive nose design produce a high ballistic coefficient, translating to flatter trajectories and less wind drift downrange.
• Improved Stability: A long driving band enhances rotational stability for tighter groups.

Performance Characteristics

The .257 Weatherby Magnum is renowned for delivering the flattest trajectory of any .25 caliber rifle cartridge in the world. This particular load—100 grain Scirocco at 3,575 feet per second—makes it equally suitable for long-range varmint work and big game hunting, depending on your quarry and distance.

What You Get

Each box contains 20 rounds of factory-loaded ammunition, ready to shoot. This is premium ammunition for serious hunters who understand that the right tool makes all the difference.
