caption_attribution_description: English: Drill round or dummy cartridge for the .30 caliber Model 1906 United States Government. The cartridge uses a modified case bearing the headstamp F A 4 09 indicating manufacture at Frankford Arsenal in April 1909. The case has been tin-plated, indented with six longitudinal flutes, and perforated three times in alternating indentations. The hollow brass bullet retains a spring-loaded steel rod exposed in the primer pocket with 1/8-inch of possible forward movement when struck by the firing pin. This rod is intended for the Hollifield Target Practice Rod device -- a pointed rod within the barrel which would be propelled out of the barrel when struck by the steel rod in the dummy cartridge to prick a paper target held just in front of the rifle.
context_page_description: 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. Dummy ammunition is distinct from "practice" ammunition, which may contain smaller than normal amounts of propellant and/or explosive. For example, the M69 practice hand grenade 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.
