A snap cap is a device which is shaped like a standard fire-arms cartridge but contains no primer, propellant or projectile.
 
Snap cap is designed to be a fake cartridge from the very beginning.
 
It serves the same function as a dummy round, but different in that a dummy is usually made from a real cartridge with its propellant and primer removed (still has the projectile and the casing).
