A thwarted Dallas shooting goes viral. If only all gun violence got the same attention

especially when Teflon coated

Teflon coatings are for barrel wear and do nothing for the ballistics.

Uh huh, vapor deposition of Teflon on full metal jacket rounds pass right through Kevlar body armor. The Teflon carrier sheaths are not for protecting the rifling, they are for hiding the rifling marks on the bullets to make them untraceable. C'mon lol.

In the second video the guy against the wall near the shooter managed to take this picture

And obviously, the mask is necessary because they always escape. (Sarcasm)

Dumb question, I suppose but why the hell would he bother wearing a mask? They always either get shot or get caught so what is the point of that? LOL

Doesn't the rounds from a rifle do that on their own?

That's just not worth it I'd think. Losing a lot of velocity to achieve the objective you listed first. *edit*-barrel size still the same would peel additional sheathing right off any ways. Rifling would still bite the round and leave makes yea?


I think this dude was a certified dumb ass. If he had the capacity to think thing through like the above, he wouldn't have done absolutely nothing while getting waxed from a pistol round at long distance.

But thank God this dude has less compiance than a teenager playing air soft. Darwin took a grade A asshole off the planet.

INCEL..ffs, what a loser..I hope it hurt.

Yes, well, 22 years old, a sad thing and his poor Family.

Maybe he had some mental disability or he was seeking suicide.

You're right,
I'm sure there is some mental illness or personality disorder, and he probably has some family who are hurting now.

The guy was definitely a tool and dumb as sh!t which was certainly a blessing, since nobody died, but that idiot. At least it thins out the gene pool somewhat. As far as velocity loss on a teflon vapor deposition round, it's very little usually. Since Teflon is so slick and has a melting point of about 330 degrees, it stays quite stable. In fact, you can get slightly higher velocities if the deposition is done thin and right. Because of this stability and extremely low friction, it can push apart the fibers in Kevlar armor. As far as a sheath goes, they are about 0.004" thick, the rounds are trimmed down to match the inner diameter. Sheath or carriers are in two pieces or halves. When they exit the barrel with the bullet, they separate. This kind of tech can be used on literally any round and you can usually tell where the shooter was positioned by the distance to the sheath pieces, after the fact.

You should see some of the rounds I made using hollowpoints, of course it helped having a multi-discipline backround and my own lab when I worked for the military. I prefer packed ammunition.

Teflon coated ammo got the name “cop killers” thanks to NBC. The ammo was designed to provide better penetration through automobile windows and doors, not for defeating body armor. The reason the ammo was found to have a marginally increased ability to penetrate body armor was because of a) the design of the bullet itself and b) the metals used. Not the Teflon.

The Teflon is very much for the purpose of protecting the barrel rather than making the bullets untraceable. The fellas that came up with the whole idea state that much pretty clearly. C’mon lol

What?

PTFE has no armor piercing capabilities.

Critics kept complaining about Teflon's ability to penetrate body armor... In fact, Teflon cut down on the round's ability to cut through the nylon or Kevlar of body armor."

Where you clearly developed weapons-grade BS.

One would think the Canadian Jason Bourne did everything at weapons-grade levels, eh?

that's a look of … Oh snap... wtf did I do.


glad he was so inept, good on the security personnel.

That's that look of "Damn, all those anti-gun articles make this sound so easy. I should have 100 kills by now "

Not metal armor piercing, Kevlar. On a nice full metal jacket it slides between the Kevlar fibers.

Now you're just being dumb. We all have a history, mine is just a bit odd because of who I worked for and the extra training in chemistry and metallurgy. Until I went with the military in the 80's, I was just an engineer, r&d, analytical instrumentation, software/hardware. When the military got their hooks in me, my job profile changed radically. Partially because of what I was designing and also because of where we were deploying the systems. When you are operational in an active campaigns and around them, you have to go in fully prepared. Maybe you've never been in an active zone? I do have some regrets but I am certainly not ashamed of doing my job well.

The link I referred you to that you didn't bother to read is about it's lack of effectiveness on Kevlar and Nylon armor.

No one likes a bull#ter.

It does "sound" good and it would decrease barrel wear, but that's not the main reason for the coating lol.

Hate to tell you but that type 2 Kevlar vest I was wearing when I got hit by 308 probably saved my life, since I was about 70kms from the base. I came out with a fractured rib. So, I trust them somewhat. If it had of been a 50 cal, wouldn't have mattered. The guy was shooting from about 600-700 metres, so I didn't hear the shot until I was already on the ground.

Better to have some protection than none at all :-)

Pay attention. We're not discussing the effectiveness of Kevlar. We're discussing the effectiveness of PTFE to penetrate Kevlar and nylon armor.

It doesn't. In fact it is woefully ineffective.

You continue to assert that PTFE will penetrate Kevlar "between the fibers". There is no such data to back that up. In fact all the data on the effectiveness of PTFE on bullets of ANY caliber shows the exact opposite of the effect you and Hollywood assert.

I am just glad he didn't pick a gun free zone like a school because it would have been a tragic massacre. The media would have pushed to disarm the populace.

In this case, he picked a place where people were armed. Only tragic for the crazy gunman which I am good with.


Anti gunners are you taking notes?

If I still had access to body gels and Kevlar armor, I would do a video. I've been out of the business for years.

Wait you mean fewer people die when there's armed people at the place to respond to the attacker? Who'd'a thunk it?
