Like most handgun cartridges of this size, it is used almost exclusively in revolvers. It is designed mainly for hunting rather than self-defense or tactical usage.


The cartridge is comparable in size to the .50 Action Express but has higher powder loads and normally a lower velocity.[3] Though not as powerful as the .500 S&W Magnum, the .500 Wyoming Express is one of the most powerful handgun cartridges commercially available today and is capable of taking any large game animal.[4] Other similar cartridges are the .500 Linebaugh, and the .50 Beowulf.
