ELI5: Explain Like I'm 5

Table of handgun and rifle cartridges

Imagine you have different toys that shoot little balls, some are small and some are big. When you want to buy more of these little balls, you need to know which ones fit in your toys.

Grown-ups use guns, which are like advanced toys that shoot bigger and faster balls, called bullets. But not all guns can shoot the same size of bullet. Some guns are designed to shoot small bullets, called handgun cartridges, and others are designed to shoot bigger bullets, called rifle cartridges.

To help grown-ups choose the right size of bullets for their guns, there is a chart called a table of handgun and rifle cartridges. This chart shows all the different sizes of bullets that can be used in different types of guns. Each bullet size has a name and number code that helps grown-ups remember which ones are the right fit for their guns.

By using this chart, grown-ups can make sure they have the right bullets for their guns, which is important for safety reasons. It's like making sure you have the right size of balls for your toys, so they don't get stuck or jammed.
