Dry firing firearms is the practice of discharging (or simulating the discharge of) a firearm without any live ammunition, or practicing with an inert laser/infrared training platform such as an iMarksman or SIRT (Shot Indicating Resetting Trigger) training pistol, and may also include the use of a target/feedback system, such as the iDryfire or LASR software.

In modern dropping block, break-action (e.g. double-barrel shotguns) and revolver firearms, the extractor is a protrusible piece with flanges on the barrel/cylinder side, which pushes rearwards on the casing's rim and slides it out of the chambers. Some such extractors can push hard and far enough that they completely clear the cases out of the ...
While artillery grain dimensions might be several inches or centimeters, the standard grains of military rifle propellant were 0.085 inches (2.2 mm) long and 0.03 inches (0.76 mm) in diameter. The Army identified this military rifle propellant as Pyro DG (for diphenylamine, graphited), and 500 tons per day were manufactured by various plants ...
