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

There's a reason NIJ tests are done the way they are.

All of those factors affect textile armor

I have yet to find any compelling evidence showing that .22LR can defeat 3a

Which is why they're generally used alongside or as reinforcement to solid armor like cermaics or metals

the reason why it is probably not addressed is because they can't define an all-encompassing criteria for what .22LR it should defeat

Exactly.

I'm sure that there is some load of .22LR out there that you can fire from a 26 inch barrel that may defeat 3A given specific conditions

however 99% of common use .22LR firearms and loads will be defeated by 3A

Because no backyard nigger plinker .22 is firing at a proper target in a proper test environment, and nowhere near the required number of plates or shots.

IIIA testing is something like 300 rounds against 20+ plates

At varying standard environmental ranges and conditions

it's not going though

You can say that all you want but the science is there.

Textile armor is so weak against small projectiles it's causing a shift to solid armors

ok, you let us know when you're done with your NIJ testing how that goes

NIJ 0101.04 does state that level 1 will defeat .22LR

lol

0101.04 was superceded.
