The Weatherby Select Plus .280 Ackley Improved with 150gr Swift Scirocco II bullets combines a classic wildcat cartridge with modern premium ammunition engineering. The .280 Ackley Improved was developed to push past the .280 Remington's limitations—P.O. Ackley's steeper 40-degree shoulder design increases powder capacity, translating to the velocity and ballistic performance Weatherby is known for. If you hunt medium to large game and want a versatile, flat-shooting round that delivers consistent energy downrange, this .280 AI load deserves serious consideration.
Swift's Scirocco II bullet is a bonded-core, boat-tail design built for reliable expansion and deep penetration in real-world hunting conditions. Paired with Weatherby's Select Plus loading, you get ammunition that's held to tight quality standards—the kind of consistency that matters when your shot counts. This 20-round box is loaded hot enough to take advantage of the Ackley's potential, yet it will cycle reliably in any .280 AI rifle.
Whether you're a handloader curious about factory .280 AI ammo or a hunter already committed to this cartridge, Weatherby Select Plus rounds deliver the velocity and accuracy you'd expect from a company that built its reputation on making rifles and ammunition work together. The .280 AI remains one of the smartest intermediate-magnum choices for hunters who want speed without the recoil penalty of the heavy magnums.

The 150-grain .280 Ackley Improved is a versatile medium- to large-game load. The Swift Scirocco II bullet's bonded-core construction and expansion characteristics make it effective on elk, deer, and similar-sized game when placed properly.
