What can happen to paintballs in very hot or cold weather?
Paintballs work well in hotter or colder weather, but they should be kept well protected from any temperature extremes. Keep them out of the heat and sun, or the raw cold. At the field, keep them sealed, shaded from the sun and protected from the cold. Too much heat can cause the gelatin shell of a paintball to soften, meaning the paintball might deform, bounce more or stop feeding into the paintgun. Never leave your paint in the direct sun. Do not buy paintballs and then leave them in your hot trunk. In colder weather, when on the field, try to keep paintballs at 60 to 70 degrees. Paintballs that get too cold will eventually become deformed, and you cannot make them back into round paintballs.
