Kopsch explained that the teflon coating, which a host of media
and lawmakers alleged was the key to penetrating body armor,
served one purpose. It helped bullets go through smooth surfaces,
like windshields and car doors, especially at oblique angles. The
former Army medical officer likened it to the teflon tip of a
walking stick. It simply grabs better.

Kopsch: "Adding a teflon coating to the round added 20%
penetration power on metal and glass."
(unquote; Kopsch is the K in KTW: the original "cop-killers")

So the purpose of the teflon coating *was* to do with AP
effectiveness, and would assist with penetrating metal armour,
especially if the bullet struck a rounded surface at an angle.

The same effect is often claimed by medieval reenactors who test
arrowheads with a lump of beeswax on the tip. I've never seen any
source material to support this as historical usage, but it works.
I guess it's a little similar to both the APC and APCR shot used
by AT guns in WW2.
