280 Ackley Improved 150 Grain Swift Scirocco– The primary difference between the standard .280 Rem. and the .280 Ackley Improved is the steeper 40 degree, which lengthens the case body and allows for about 5 percent more powder capacity. When P.O. Ackley gave the .280 Remington a steep 40-degree shoulder and straightened out most of the cartridge case’s body taper, he likely knew he was on to something special. However, it’s doubtful he anticipated that more than a half-century later, his .280 Ackley Improved cartridge would blossom into a favorite of savvy open-country hunters across the West.
Decades ahead of his time in cartridge design, Ackley became a household name for his work, at least among cartridge enthusiasts. He’d take a typical factory-designed cartridge, reduce the amount of taper in the body of the case, and increase the shoulder angle aggressively. These modifications resulted in added capacity, which increased velocity, and less case stretch, which resulted in longer case life. The .280 AI’s additional case capacity does good things, but it doesn’t change laws of physics. With equal barrel lengths, the Ackley Improved version gets you about 100 additional fps of velocity with a 140-grain bullet and a 24-inch barrel.
