>>5462261If there is no barrel all the pressure when the powder explodes gets lost, and since the shell tends to weight less than the bullet is more than probable that the sell gets fired like a rocket and the bullet stays practically in the same place, maybe it could harm the lips but there's no way it can kill a man.
The mithbusters tested it out throwing all kind of bullets into a fire, the shells traveled more distance than the bullets itself.
Anyway your ears would be ringing for a long time.
