A dummy round or drill round is a round that is completely inert, i.e., contains no primer, propellant, or explosive charge (filling).{{cite book |last=Brown |first=Edmund G. |author-link =Jerry Brown |title =Handgun Safety Certificate |publisher =California Department of Justice |date =2009 |location =West Sacramento, California |page =52 }} It is used to check weapon function, and for crew training.[http://www.fas.org/man/dod-101/sys/land/m922.htm M922/M922A1 40mm Dummy Rounds] (fas.org) Dummy ammunition is distinct from "practice" ammunition, which may contain smaller than normal amounts of propellant and/or explosive.[http://www.fas.org/man/dod-101/sys/land/m781.htm M781 40mm Practice round] (fas.org) For example, the M69 practice hand grenade[http://www.fas.org/man/dod-101/sys/land/m69.htm M69 practice hand grenade] (fas.org) emits a loud pop and a puff of white smoke.

A dummy is not to be confused with a blank, a cartridge for a firearm that contains propellant and a primer but no bullet or shot; a dummy does not produce an explosive sound like a blank does.
