Question about body armor

[gym]

So that was just an "old wives tale" , the teflon coating? I remember back 40 yrs ago, guys spraying their bullets in the army with teflon and all kinds of junk.Also cutting the crosses in the tips 'which I believe was illegal" for greated expansion, dum dum bullets. Any truth to that?

No idea on the notching the bullet, but I do recall someone saying that at higher pressures teflon actually starts to act as an adhesive not a lubricant, so teflon coated things at high pressures get "sticky". Again, not good for penetration.

It doesn't really make them expand, it actually makes them fragment depending on the bullet. The Box O' Truth actually tested this, the test also covers seating a bullet backwards and the original Dum-Dum Arsenal design of just cutting off the tip.

gym, yes, teflon coating doesn't do JACK DIDDLY SQUAT to make a bullet penetrate armor.

It was used to protect the rifling of the weapon being fired since the projectiles which they were using, that would penetrate armor, were solid-machined chunks of metal harder than the steel on the barrels (nickle steel, etc).

Teflon is just a lubricant to protect the barrel; no different than Molybdenum coatings that some rifle shooters use to reduce friction.

Do you guys remember when there was a big deal made about teflon coated bullets penetrating vests. I think it even dragged over into the tv and movies in the late 60's and early 70's. I guess that was all fiction.
Having had a problem myself "2 years in court before all charges dropped" in the early 80's for having super vels, "which we have covered before" in my PPK's, in NYC.
Which were just a second primer inserted into the tip of a hollow point, I remember spending 12 hours in a police station. This was because they were still selling them in gun stores.But no one told any of the owners that they were illegal after Reagan was shot with an exploding bullett , thus causing all of them to be banned. As there was no internet back then, you were magically supposed to know that the bullets you were sold with the gun, were now illegal.
But it all started with 13 cops standing around looking at a bullett that they never saw before. When I found the receipt for the purchase of them along with the gun," I got them together", that was more or less the end of the case. Don't throw stuff away, You may need it someday. They were very polite when giving me back my guns, but "we also mentioned this" scratched the nickel guns slide by etching the complaint number on it thus ruining the gun.
That's why I can't stand the way they treat civilian gun owners in those states, it's as if you are the bad guy. I made my mind up then that I was getting out of there ,and any place else that had that mentality. And why I advise people when asked where should I live etc. You are not a free man is some places. You are at the will of tyranical politicians. Funny thing is they shipped my weapons from Dept to Dept , so I wouldn't be in violation of any laws when I brought them down to where I moved, and they did it for free. A detective told me about it, some kind of departmental perk.
I picked them up from a Capt friend in Jupiter, who I haven't seen since. His patrol route was driving around, Perry Como's estate, now deceased. you old timers will remember, Perry lived in Jupiter. All over a bullet.They returned everything but those super vels.
