As sometimes happens in the world of rifle cartridges, the 280 AI (Ackley Improved) is becoming more popular than its parent, the excellent 280 Remington. Since they use larger diameter bullets, the .280 Rem, .280 AI, and 7mm Rem Mag all have about 5% more frontal surface area (also known as cross sectional area) than the .270 Winchester (.0633 vs .0603 square inches).
