Weatherby Select Plus 257 Weatherby Magnum Ammunition, 100 Grain Swift Scirocco II, 20 Rounds

The Weatherby Select Plus 257 Weatherby Magnum ammunition pairs a legendary cartridge with a modern, premium bullet design to deliver flat-shooting performance and deep penetration on medium to large game. Built around the Swift Scirocco II—a bonded bullet engineered for controlled expansion and weight retention—this load is engineered for hunters who demand accuracy and terminal performance beyond standard factory ammo. The 100-grain projectile hits your target with 2838 ft-lbs of muzzle energy at 3575 fps, giving you the velocity needed to stretch your effective range without sacrificing the accuracy that counts when it matters most.

The 257 Weatherby Magnum itself is a no-compromise cartridge: it's faster than standard 25-caliber rounds, flatter-shooting than most magnum alternatives, and capable enough to handle elk, mule deer, and similar-sized game at distances where precision is everything. Weatherby's Select Plus line reflects decades of proprietary load development, so you're not just buying ammunition—you're inheriting Roy Weatherby's expertise. This is ideal ammo for hunters who've already invested in a quality 257 Magnum rifle and want brass that performs reliably, shot after shot.

Each box contains 20 rounds, packaged for secure storage in your hunting pack or reloading station. If you run a 257 Magnum, this ammunition deserves serious consideration before your next season.
