In general paintball guns are designed to shoot paintballs at a speed of 280-300 feet per second (fps).
The maximum speed for a paintball gun is regulated by industry standards and safety guidelines. Most fields and tournaments have a maximum velocity limit of 280 fps, and players are required to use a chronograph to measure the velocity of their gun before play.
It’s important to note that firing a paintball at high velocity can be dangerous and cause serious injury. That’s why it’s important to always follow safety rules and guidelines, and wear appropriate safety gear such as goggles and masks to protect your eyes and face while playing paintball.
