.223 Ackley Improved Load Data

Alternative names: .223 AI, .223 Remington Ackley Improved, .223 Rem AI, .223 Remington Improved

Our load data for caliber .223 Ackley Improved covers 275 bullets from 28 manufacturers and a total of 17325 load recipes. In addition, our members have shared 10 load recipes.

The .223 AI is based on the .223 Rem but has been modified by gunsmith P.O. Ackley to have a steeper shoulder angle (typically 40 degrees) and less body taper. This design allows for more internal case capacity, which can hold more powder and potentially deliver higher velocities.
