Reloading powder is available in two primary types, smokeless powder and black powder. For metallic and shotshell reloading, the usual choice will be one of the many smokeless powders, like Varget powder or one from the Nobel Sport selection. Primers are made in various sizes and types depending on the application, like CCI 250 primers which are large magnum size. Federal primers and Cheddite primers are two popular choices. Black powder is primarily used in muzzleloading firearms but is also used in black powder cartridge rifles.
