Weatherby Select Plus .280 Ackley Improved 150gr Swift Scirocco

Weatherby Select Plus .280 Ackley Improved

Weathery Select Plus ammunition represents the pinnacle of factory rifle ammunition, combining proven cartridge design with premium bullet construction for hunters and shooters who demand the best.

The Cartridge

The .280 Ackley Improved was developed by P.O. Ackley, a wildcatter whose innovations paralleled those of Roy Weatherby himself. By steepening the shoulder to 40 degrees, Ackley increased powder capacity over the standard .280 Remington, resulting in superior velocity and flatter trajectory. Weatherby's interpretation of this cartridge pushes industry standards for both ballistics and velocity.

The Load

This particular offering pairs the .280 Ackley Improved with Swift Scirocco bullets—a premium projectile known for:

• Consistent expansion across a wide velocity range
• Bonded construction for reliable penetration and weight retention
• Aerodynamic design for extended range capability

At 2925 feet per second, this 150-grain load delivers the flat shooting characteristics the .280 AI was designed to achieve, making it ideal for medium to large game at extended ranges.

What You Get

Each box contains 20 rounds of ammunition loaded to exacting Weatherby standards. Select Plus ammunition is the result of Weatherby's commitment to providing hunters and shooters with factory ammunition that performs like hand-loaded precision loads.
