The practice involves discharging specially designed cartridges from firearms modified or manufactured specifically for that purpose. These cartridges contain gunpowder but lack a projectile. A wad, crimped casing, or other material seals the cartridge, containing the propellant and producing a muzzle flash and report upon firing. An example would be a theatrical production utilizing such firearms to simulate gunfire for dramatic effect.
This activity finds applications in various fields. Film and theatrical productions utilize it to create realistic sound and visual effects. Military and law enforcement agencies often incorporate it into training exercises to provide a safe yet immersive simulation of combat scenarios. Furthermore, historical reenactments and competitive shooting disciplines sometimes employ this technique. Historically, modified firearms firing blank cartridges played roles in ceremonies and celebrations requiring loud reports, though safer alternatives have largely replaced them.
