All right, not sometimes, but happens. That shell was a dud, such is life. As far as I know there's pointy thing at the end of the barrel, the shell has a charge at the back which gets ignited and that propels it out of the barrel. The charge was faulty.
Sometimes a round gets stuck in the rifle, sometimes an airplane falls out of the sky. Shit happens.
