The .500 Auto Max is a rimless version of the .500 S&W Magnum which was modified to operate in the AR500- a modified AR-15. The modified S&W .500 allows the cartridge to be loaded and cycled in a semi-auto rifle. The rest of the cartridge remains unchanged, creating an immensely powerful rifle cartridge.
