Pepper Balls for Paintball Guns

Pepper Balls works in all Paintball Guns. Pepper Ball Ammo is a projectile, similar to a paintball, but made from different materials I'm planing to buy some .68Cal pepper balls for my paintball gun. Anyone have any kind experience with it? Thanks :cool: Rock people have "pepper balls" and guns to go with those pepper balls This would mean that it could be used in some ordinary paintball is the difference between a peperball gun and a paintball gun? Are they the same except the ammo...
