While the term "gunpowder" is often used to refer to any type of propellant used in firearms, the specific mixture used in bullets is typically black powder or smokeless powder.
* Black powder is a traditional gunpowder made from charcoal, sulfur, and potassium nitrate. It produces a lot of smoke and residue.
* Smokeless powder is a modern type of gunpowder that produces less smoke and residue. It is typically made from nitrocellulose and other ingredients.
It's important to note that the term "explosive" can be misleading. While the gunpowder inside a bullet does detonate, it doesn't explode in the same way as a bomb. The combustion of the gunpowder produces a rapid expansion of gases that propel the bullet down the barrel of the gun.
