The era when subversive fuckheads in Hollywood made movies that lied to gullible retards who believed it, then used those lies to ban stuff.
That dumbfuck Lethal Weapon 3 movie where they falsely portrayed the Evil Huwyte Maing using "cop killer" bullets coated in teflon. I disremember if it was "they sprayed them" with Teflon (like, out of a can like it was hairspray) or it was somehow industrially coated in Teflon, but it was pretty egregious. Even past me in 1992 was calling bullshit.
In my opinion, Olin Corporation should have sued that disloyal commie fuckhead Richard Donner and Warner brothers for liable, as that false claim gave a great deal of fuel to the fire that led to the Black Talon being banned.
I take it most of the people in this thread know this already, but Teflon coated projectiles became a thing because it reduced fouling in the barrel of a firearm, that's it. It had nothing to do with penetrating armor - it is velocity that enables a projectile to penetrate armor, not what the projectile is coated with. Like a rail gun shooting a 1kg block of aluminum at a M1A2 Abrams MBT at 25,000 fps and having that block of aluminum go through it lengthwise, no stops.
Add in a bunch of MD's all crying about how tore up the Culture Enrichers were in the ER in Chicago and Baltimore during a long summer weekend and the Talon was doomed.
