The rifle will fire without a pellet, but over time it will ruin the air chamber and air piston inside the chamber. When you pull the trigger the air piston slides forward inside the air chamber compressing the air behind the pellet. At the last moment it actually slows down as the pressure builds and fires the pellet. Without a pellet in the loading port the piston has no resistance and just slams against the stop. This will eventually ruin the rifle.
