Fine tuning the errors (why didn't he get a gun geek to edit the piece?):

>>For example, in the movie Lethal Weapon 3, a so-called "Teflon bullet" from a medium-power handgun was supposedly able to penetrate several inches of hardened steel on a bulldozer blade.

Bulldozers don't use hardened steel, they use mild steel because it is tougher.

In the real world, however, no bullet could possibly perform such a stunt.

>>Also, reduced abrasion means that fewer tiny lead air particles are produced, so the air is cleaner — an especially important consideration at indoor shooting ranges.

Most bullets are copper jacketed (so any or this phantom "abrasion" would be copper particles.) Those who shoot old-fashioned lead slugs rarely use teflon, and no manufacturer sells a teflon coated lead slug that I am aware of.

>>The Teflon helps the bullet "grab" a hard surface such as glass or metal, and thus significantly reduces the risk of a dangerous ricochet.

Nonsense. Teflon reduces friction. The key is that hard steel and brass bullets that do "bite" into angled windshields and door panels need to be teflon coated to avoid barrel damage.

>>Similarly, canes or walking sticks are often coated with Teflon, so that they will not slip on hard, smooth surfaces.

Hard to believe.

It would be nice if our side would be scrupulously accurate on such accuracy-sensitive issues.
