God, will this urban myth never die?
THE COATED BULLET CORE NEVER CONTACTED THE BARREL. The central bullet was
contained in a copper cup, and appeared as a semi-jacketed design in
appearance. The teflon was added to help limit ricochets from hard,
included surfaces, namely windshields. Under high compression teflon almost
acts as an abrasive, or at least tacky substance, this tended to direct the
motion of the bullet into the surface to inhance penetration. The teflon
was never intended nor used to lubricate anything. The entire bearing
surface of the round was supplied by the copper cup around the base of the
round.
Further a moment of thought would make this clear. What happens to your
bore (barrel) if you attempt to shove a hard non-deforming object through
it? Can you say excessive pressure, stripped rifling, bolt in the forehead,
ect? After all the orginal design had cores made of tungsten.
