Destruction of the facial skeleton due to shotgun blast

Spain. Destruction of the facial skeleton due to shotgun blast. No further info. Shotguns differ from rifles and handguns in construction, ammunition, ballistics, and use. Rifles and handguns fire a single projectile down a rifled barrel. Shotguns have a smooth bore. Although they can fire a single projectile, they are usually employed to fire multiple pellets. Rifled shotgun barrels, intended for use with slugs, are available. Shotguns may be autoloaders, pump (slide action), over/under, side-by-side, bolt action, or single shot. Some shotguns usually intended for military and/or police use convert from semiautomatic to pump action and back as the user desires.
