You can use just about anything for a sport. Such as a ping pong ball for beer pong. I believe that any gun can be used for sport from a single shot .22 all the way to a browning m2hb. The only thing is how you play that sport and how the player uses the tool at hand. You can use the ping pong and throw it in the cup across the table or you can chuck it at the guy's face.
If my answers frighten you then you should cease asking scary questions.
