A cartridge specifically designed for starting pistols, theatrical productions, or training exercises contains no projectile. It consists of a casing, primer, and usually a wad of paper or plastic, but crucially, no lead or metal bullet. This ammunition creates a loud report and muzzle flash upon firing, simulating a live round without the danger of a projectile. The casing often features a crimped or closed end to distinguish it from live ammunition. A specific example would be a 9mm PAK blank cartridge, frequently used in starting pistols for sporting events.
The absence of a projectile allows safe use in situations where the effect of a gunshot is required, but a projectile would pose an unacceptable risk. This is vital for various applications, from film and theatre productions requiring realistic gunfire sounds to dog training and sporting events. Historically, blank cartridges also played a role in line-throwing devices for maritime rescue. This relatively safer alternative to live rounds contributes significantly to enhancing safety protocols in diverse fields.
