Strange, the problem with rap is they don't actually deal with firearms. They use words and phrases that sound cool to the uneducated. There are more calibers of firearms than you can imagine. There is a caliber for every possible use and fancy. If there isn't a production caliber, chances are someone has wildcat'd it and tried to make one.
Firearms are a world you either delve into deeply trying to learn or you ask knowledgeable people about, earnestly trying to find information. Rap music is not a good source.
Since you ask, the biggest caliber is (to the best of my knowledge) the .700 Nitro Express. The smallest caliber is much harder to define. Are you asking in terms of velocity, or energy, or bullet diameter?
