Ammunition refers to the materials used in firearms and artillery to create projectiles that can be fired. This includes bullets, shells, and cartridges, which are designed to be loaded into weapons like rifles, handguns, and cannons. Ammunition is typically made up of a projectile, a propellant, and a casing that holds everything together. The effectiveness of ammunition depends on various factors, including its design, caliber, and the type of weapon it is used with. Different types of ammunition serve specific purposes, such as hollow-point bullets for self-defense or armor-piercing rounds for military applications. Proper storage and handling of ammunition are essential for safety and performance.
