Definition
A blank shell is a cartridge that contains gunpowder but no projectile (like a bullet or slug). It is used to create a loud noise or simulate gunfire without the danger of a live round. Think of it as a noisy firework designed for a gun. Unlike a live round, it doesn't fire a projectile. It's commonly used in theatrical performances, movie productions, and military training exercises. The blank shell provides a realistic sound effect without the risk of injury.
