The .500 Auto Max was designed by Big Horn Armory for use in their AR500 rifle, which is based on the AR-10 sized platform. The .500 Auto Max is essentially a rimless .500 S&W Magnum. It is a very versatile cartridge, it can handle anything from prairie dogs to pachyderms to Peterbilts, truck stopping power in a platform weighing less than 10 lb. The .500 Auto Max uses the same reloading dies, shell holders and load data as the .500 S&W Mag, with the exception of requiring a taper crimp instead of the standard roll crimp. This is due to the Auto Max headspacing off of the mouth of the case instead of the rim.
