The heat is from the friction of the bb spinning and contact with your skin. Whenever the bb leaves the barrel the pocket of air cushioning and pushing it out should cool it down so heat shouldn't be a factor.
Are these bio bb's? Non bio are stable plastic that shouldn't degrade, emit smell, etc.
Maybe it's bio bb's sweating due to light and heat in storage that it'selting half way through the barrel?
