.500 Wyoming Express

The .500 Wyoming Express or .500 WE is a "big bore" handgun cartridge. Freedom Arms introduced the cartridge in 2005 for their Model 83 .500 WE revolver.

Like most handgun cartridges of this size, it is used almost exclusively in revolvers. It is designed mainly for hunting and wilderness defense against medium to heavy North American game.

Overview
The .500 Wyoming Express is dimensionally similar to the .50 Action Express but can be loaded to a higher power level and utilize heavier bullets, due to its greater maximum chamber pressure and longer cartridge overall length. Unique among handgun cartridges, it is a belted round, which allows for a heavy roll crimp to be employed without compromising headspace, as with the .50 AE. Though not as powerful as the .500 S&W Magnum, the .500 Wyoming Express is available in more compact revolvers, and for those capable of mastering its heavy recoil, it is adequate for harvesting any North American game animal at short to moderate range. Conceptually similar cartridges include the .500 Linebaugh, .500 JRH, .475 Linebaugh, and .454 Casull. However, the .500 Wyoming Express is somewhat more powerful than these rounds. It is ballistically comparable to the .500 Maximum, 50-70 Government, and .50 Beowulf cartridges, which are usually chambered in substantially larger firearms.

While .500 Wyoming Express brass was out of production for several years, it can be formed from .50 AE through a multi-step swaging process. Brass formed in this manner is currently available from TII Armory, as well as loaded ammunition.
