A "round" is another name for a bullet or cartridge. Historically, the word referred to a single mass discharge by a group of weapons, then to a single discharge by one weapon, then to the projectile so discharged; in modern weapons, it usually refers to the bullet/propellant/casing combination called a "cartridge." It does not, and never has, referred to the number of cartridges in a standard load. In Archery, it does refer to a number of arrows fired in a scoring round, but the difference is obvious.
