This premium ammunition combines Weatherby's precision manufacturing with the ballistic advantages of the 280 Ackley Improved cartridge, providing hunters with flat trajectory and devastating terminal performance on medium to large game.

What Makes This Different

The 280 Ackley Improved cartridge offers significantly higher velocity than standard 280 Remington loads while maintaining manageable recoil.
