What happens when a cartridge is missing gunpowder?

When a cartridge is missing gunpowder, it results in a complete misfire. This is because gunpowder is essential for the propulsion of the bullet. Without the appropriate amount of gunpowder, the cartridge lacks the necessary energy to generate the high-pressure gas needed to propel the bullet down the barrel. As a result, the primer may ignite and create a small explosion, but there won't be enough force to fire the projectile, leading to a complete failure of the cartridge to function. This situation can pose safety concerns, as a misfire can potentially cause the firearm to malfunction or lead to a situation where the firearm is not properly discharged, leaving the shooter unable to safely assess the status of the weapon.
