The .223 Ackley Improved, designed by P.O. Ackley, is a modified .223 Remington with a steeper 40-degree shoulder and less body taper. Introduced in the mid-20th century, it boosts case capacity and velocity while extending brass life. Popular with varmint hunters, it offers improved performance without sacrificing reliability or versatility.
