(n.) The projectile fired from a rifle or handgun. The term does not encompass the entire round of ammunition. A bullet may be made of lead, lead alloyed with other metals (e.g., tin or antimony); a lead core surrounded by a jacket made of copper, cupro-nickel, gilding metal, brass or steel; or, infrequently, made of another metal, such as solid brass. Sometimes, lead bullets are surrounded by a paper patch.
