- The .50 AE (Action Express) is a large-caliber, centerfire pistol cartridge developed by Action Arms in 1991 for use in their Desert Eagle pistols. It was designed to provide high performance and power from a short-barreled handgun, allowing users to take down even the largest game animals.
The .50 AE has a large case capacity which results in higher velocities, flatter trajectories compared to other rounds with similar bullet weights, making it ideal for hunting applications. Its wide selection of factory ammunition provides excellent accuracy and consistent performance from the Desert Eagle platform.
