I just read the wiki for a quick primer of knowledge on these rounds, and remember the term from movies, when I was younger, perhaps one of the Lethal Weapon series?

As a weapons and firearm knowledgeable adult I know that applying teflon alone does not an AP round make. The teflon ban is a typical misunderstanding of firearms technology, to penetrate anything, including armour, one only needs to rely on physics, typically a small, dense projectile, with a lot of velocity is the direction to go. For example, with the LAV III, 25 X 137mm Bushmaster Cannon, our Sabot rounds (APDS-T) are a 25mm diameter discarding sabot with a tungsten dart, which is about the same diameter as a common pencil, that is what is fired to deal with Light Armored Vehicles.

I understand the concern with preserving the lives of police and similar services but to attribute the danger to the stuff that plumbers use to seal pipe joints, or flying pans use to keep eggs from sticking is borderline hilarious.

The KTW rounds are a neat find, all this time I thought the "cop killer" termed ammunition was a creation of movie fantasy.
