Dummy round
A dummy round or drill round is a round that is completely inert, i.e., contains no primer, propellant, or explosive charge. It is used to check weapon function, and for crew training.〔(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.〔(M781 40mm Practice round ) (fas.org)〕 For example, the M69 practice hand grenade〔(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 but no bullet or shot: a dummy does not produce an explosive sound like a blank does. == References ==
