A slow burning rate rifle powder for cartridges such as .270 Winchester and 300 Winchester Magnum. AR2213SC replaced AR2213 in the Australian reloading market. AR2213 had been produced by ADI only for supply to the Australian reloading market and was only manufactured every three to four years. As a result, the powder that reached the shooter may not be of recent manufacture and stockout situations occasionally occurred. ADI produces AR2213SC for the North American reloading market and is in regular production. This enables ADI to be in a better position to guarantee supply.
