A metal projectile is a type of ammunition used in firearms and other weapons. It is typically made of lead, steel, or other metals and is propelled by the force of an explosive. Metal projectiles are used for a variety of purposes, including hunting, target shooting, and military applications. They are also used in some non-lethal weapons, such as paintball guns. Metal projectiles are designed to be accurate and have a high velocity, making them effective at long ranges.
