No, throwing a bullet into a campfire would not cause the bullet to fire. Firearms operate on the principle of contained explosions within a specifically designed chamber, where the bullet is seated. Several factors are required for a bullet to be fired from a firearm:
Ignition: Firearms use a controlled ignition system, typically a firing pin striking a primer located at the base of the cartridge. This ignites the propellant inside the cartridge case.
Confined Space: The cartridge is designed to be seated firmly in the chamber of a firearm, providing a confined space for the controlled explosion to occur. This containment directs the expanding gases and propels the bullet down the barrel.
In the scenario you described, throwing a bullet into a campfire would subject the bullet to intense heat, which could potentially cause the propellant inside the cartridge to ignite. However, the bullet is not confined within a chamber, and the combustion gases would not be effectively directed to propel the bullet forward. The result would likely be an uncontrolled release of energy, leading to an explosion or fragmentation of the cartridge and bullet, rather than the bullet being fired in a specific direction.
It's important to note that tampering with ammunition or exposing it to extreme heat or fire is extremely dangerous and can lead to unpredictable and hazardous outcomes. Handling and disposing of ammunition should always be done following proper safety protocols.
