I keep hearing about joules and FPS and that you need to pass the chrono before playing, but I don't quite understand what each measures or what's normal. Can you explain it to me simply?

Basically, FPS (feet per second) is a unit of velocity measured with a chronograph, similar to kilometres per hour. What's the point of this? So that, by combining that velocity with the weight of the BB you're using, we can calculate the impact energy (measured in Joules).
In summary: we need a unit of measurement to know when a shot can hurt or cause damage. Although the rules can vary depending on the field, the standard energy limits in Spain are usually:
Rifles and secondaries: 1.14 J as a general rule.
Designated Marksman Rifle (DMR): 1.87 J.
Bolt-action Sniper: 2.81 J.
I hope this helps you, Pablo.
