U.S.A. –-(Ammoland.com)-In 1982 NBC ran a "Prime Time" special on Teflon-coated bullets labeling them "armored piercing" bullets. Their "expert" claimed that the Teflon increased the bullet's penetration power by 20%. The news show argued that these bullets were a danger to police. In this special, NBC created the term "cop killer" for all armor-piercing bullets.
The truth of the matter was that Teflon did not increase the penetration power at all. In fact, Teflon cut down on the penetration power of the round. The Teflon was used to improve the life of the gun owner's barrel, but this was in 1982 and the World Wide Web didn't exist to correct that wrong.
People were not as skeptical as they are now, and the confidence of the truthfulness of the mainstream media was high. The alternative media was just a blip on the radar. It only existed in mailings from small organizations that didn't have the capital to reach the masses.
Anti-gun advocates used this mischaracterization of Teflon-coated bullets to push for the banning of armor piercing rounds for "the safety of law enforcement officers."
In August of 1986 HR 3132 — PL 99-408 was passed by Congress and signed by President Reagan. The new law would ban any handgun round that's core consisted of tungsten alloys, steel, iron, brass, bronze, beryllium copper, or depleted uranium. It would also prohibit any handgun round whose jacket weights more than 25 percent of the total weight of the projectile.
The public was banned from access to armored piercing handgun rounds. That is until now.
A libertarian aerospace engineer named Austin Thomas Jones didn't like the fact that the government had access to the armored piercing handguns rounds, but the government prevented the general public from owning them. He viewed the law as tyrannical.
Jones has designed soft armor for combat sports. He developed micrometeoroid shielding for soft-bodied spacecraft such as modules for the International Space Station. Micrometeoroid moves at speeds that far exceeds that of bullets, and the strength of the material must be far superior to that of soft body armor.
The work of Defense Distributed on 3D printed firearms inspired Jones to take action to use science to defeat the armored piercing bullet ban. He read through the law and noticed that only certain metals were banned from use in bullets. He thought he could defeat draconian law by simply finding a material that wasn't banned by the law and designing a superior projectile.
