Yes, blanks can be used in real guns. Blanks are specially designed cartridges that contain gunpowder but lack a bullet or pellet at the tip. They are commonly used in various applications such as military training exercises, ceremonial events, and theatrical performances. The purpose of blanks is to create the sound and visual effect of gunfire without actually firing a projectile. These rounds are widely available for different types of firearms, including pistols, rifles, and shotguns.
