Air Force Academy cadet makes body armor breakthrough

This technology looks very promising. It appears that the phenomenon was well known but that no one had made the connection to body armor.

Charlie, with your chemistry background I'd be curious to know if you'd ever heard of this hardening-upon-impact property.

The story makes the 9mm look great on penetration. Thanks, but I'll go with what Mas said years ago; one .45ACP is better than half a dozen 9s when some idiot DA decides to file on you.

I have heard of materials that harden on impact but just as a lab curiosity years ago.

Why in the world would the cadet "have" to change majors?

That struck me as curious too, Charlie. I chalked it up to a reporter misunderstanding the facts (surprise!), but I guess it's possible that the academic department discontinued her major.

The reporter also misunderstood the term "Cadet 1st Class". He took it to mean a cadet in his or her first year. In reality, a freshman is a Cadet 4th Class, and a Cadet 1st Class ("firstie" in the vernacular) is a senior.

I know Mas Ayoob has made a great living preaching about (among other things) what a prosecutor will try to do to you if you use this or that ammunition, but in all the trials of self-defense shooters I've ever followed I've never heard of the ammo becoming an issue...except when too much of it was allegedly expended.

Has this become one of those "oft repeated but rarely borne out" legends?

That was what I was alluding to.

When I was in jr. High school I learned about some common household cooking powder.....I'm racking my brain and can't remember WHAT ... that formed a liquidy goo when mixed with water that seemed to harden when handled dynamically. Trying it at home I found it worked. But I would never claim or believe it would stop even a .22, let alone any centerfire round.
I can believe there might be other chemicals/materials that might possibly work....but mark my words; I ain't volunteering to be the guinea pig!

I'll bet it was cornstarch.

Cornstarch in water will form a non-Newtonian fluid.

Depends upon how picky you're being. I do faintly recall a case where the PA was jumping all over Black Talon.......until the defense brought out that was the same ammo the local PD was using.

There's also the Fish case in AZ where the PA successfully demonized 10mm JHPs as demonstrating eeeevile intent. Fish was eventually freed, but served time and died owing almost $500K in legal fees.

I think I'd avoid something like DRT ammo and a few others that were egregiously aggressive/suggestive-Zombie Max also comes to mind. I really don't worry about using 9 mm and the number of hits.

Once upon a time I did some of what's now termed "litigation support". If you don't think an ambitious attorney won't dig up any conceivable suggestive or bad prior act or fact and attempt to use it, you're sadly mistaken. And that was just civil proceedings.

There are times when I think Mas is overconservative, but I think he *has* to be because of Least Common Denominator since he can't develop a unique class for each jurisdiction.

Be prepared for the worst some ambulance-chasing Waste of Viable Donor Organs can spring on you, and anything short of that becomes an unexpected bonus.

Wish he were still around here to weigh in on this... think the only place I've seen him online for the past few years is his own blog.
