where are the bullets held in a gun
Bullet A bullet is a component of firearm ammunition and is the projectile expelled from the firearm's barrel. The term is from Middle French and originated as the diminutive of the word boulle (boullet), which means "small ball".[1] Bullets are made of a variety of materials such as copper, lead, steel, polymer, rubber and even wax. They are available either singly as in muzzleloading and cap and ball firearms,[2] or as a component of paper cartridges[3] and much more commonly metallic cartridges.[4] Bullets are made in a large number of shapes and constructions depending on the intended applications, including specialized functions such as hunting, target shooting, training and combat.
