I was reading my new copy of APG and read the article about reball. Now I had heard of Reball before. They're .68 caliber rubber balls. The suggested Chroning point is 220 fps. They seem to fire the same as paintball do. They can be cleaned, dried, and re-used. Think about it, you could rent your school's gym for a great day of fun. Who knows.. school districts might consider allowing paintballing as a P.E. course. Let me know what ya'll think!
