Dummy and Blank Ammo are often confused. While blank ammunition tends to contain powder and wadding designed to quickly disintegrate after exiting the barrel, dummy ammunition contains no propellant. This makes blank cartridges the ammunition of choice for western stage props, starter pistols, and use in the film industry. Dummy cartridges are often used to check a weapons function and to use in basic firearm training. Because they do not contain propellant, dummy rounds cannot fire or cycle a gas operated reloading system.
