The .50 AE (Action Express) is a powerful handgun cartridge developed in the late 1980s. It was designed for use in firearms like the Desert Eagle, a semi-automatic pistol known for its large size and high stopping power. The .50 AE is notable for its large bullet diameter, measuring .50 inches, and is capable of delivering significant energy upon impact. This cartridge is primarily used for hunting and target shooting due to its impressive ballistics. The .50 AE can penetrate tough materials and is often favored by enthusiasts who appreciate its unique performance characteristics. However, its recoil can be substantial, making it less suitable for inexperienced shooters.
