What might happen if a firearm is overloaded?

When a firearm is overloaded, it means that there are more gunpowder or projectiles loaded into the cartridge than the manufacturer specifies. This excessive amount of propellant can create increased pressure within the chamber during firing. Firearms are designed to operate within specific pressure limits, and exceeding these can lead to catastrophic failures.

A malfunction caused by overloading can result in the firearm exploding, which poses serious risks to the shooter and bystanders. This can lead to severe injuries or even fatalities, as well as damage to the firearm itself. It's vital for gun owners to adhere to the manufacturer's guidelines and specifications when loading ammunition to ensure safe operation.

The other options suggest improvements in performance, speed, or accuracy, which are misleading. Overloading does not enhance a firearm's capabilities but rather compromises its safety and functionality.
