Blank ammunition is a type of cartridge that contains gunpowder but no projectile. It is designed to produce a loud noise and a muzzle flash when fired, simulating the sound and feel of real gunfire without the risk of shooting a bullet. Blank rounds are commonly used in training exercises, theatrical performances, and film productions to create realistic gunfire effects. While blank ammunition is safer than live rounds, it can still pose risks, especially at close range. The gases and wadding expelled from the firearm can cause injury, so proper safety precautions must be taken when using firearms with blank ammunition.
