"Fixed it". No you made it worse. The police don't by "bullets", they by cartridges. Multiple cartridges are known as "ammunition".
A cartridge is composed of four separate components; the shellcase, the primer, the propellant powder and the bullet.
Bullets are to cartridges as flour is to bread, as cement is to concrete, etc. When will you ever learn the terminology?
