When a cartridge fails to fire after the primer has been struck by the firing pin it is called?

When a cartridge fails to fire after the primer has been struck by the firing pin, it is called a "misfire." This can occur due to various reasons, such as a faulty primer, inadequate ignition of the powder, or issues with the firearm itself. Misfires can pose safety risks, so it’s important to handle them with care, typically by waiting a short period before safely clearing the firearm.
