theres tons of companies producing NIJ standard armor
which are rated for specific calibers
here, let me lok at NIJ 1010-06
if a cop is shot by said caliber
body armor standards as of 2008
wearing NIJ armor
that is supposed to stop it
would that not make a juicy case for a slam dunk lawsuit?
shush now little one
NIJ standards are here
Let us peep
that being said, how exactly is it that these companies stay in business?
unless their armor actually stops the rated threat

.17HMR 17gr doing 2600 fps out of a rifle
goes through IIIA
discussion is related to .22lr not .17hmr
much faster than .22lr or 5.7x28
I have a whole new respect for .17HMR
Not gonna lie
However, back to the argument
II and IIA is designed to stop 9mm and .40 round nose
FMJ
No AP
Based on the test criteria, the armor needs to have limited BFD
Which means it's not meant for penetrative ballistics, it's basically a kevlar shock pad.
A small, fast round will penetrate textile armor readily
but .22lr isn't .17HMR fast
In fact, based on the 2-4-16-64g test criteria for fragmentation resistance, armor rated for actual AP threats is *weaker* against 2-4g threats.
even .22 mag isn't fast enough
Which requires its own type and technique of textile weaving to defeat

something something thread strength against targets they can't squeeze
what vest
what age
what humidity
what angle
what load
what location
what condition
how many rounds
