What do you think matters more?

compare to a 223 which is a 55gr+ at 2800fps+

velocity and sectional density

big difference

True but your original point was "Kinetic energy is based on velocity not mass."

Impact energy increases linearly with mass but quadratically with velocity

Ergo, you can accelerate sand grains fast enough to crater a continent

.22lr still isnt making it through soft body armor

agreed

.22 routinely defeats soft armor though

sure, if you consider body armor to be cotton and leather

Not even kevlar or aramis

aramid

But Rofl, that isn't going to work for a handheld weapon system in this century.

think about it like this, 5.7 cannot defeat 3a most of the time

and it has higher sectional density and higher velocity than .22LR

The idea of a sand grain cratering a continent with velocity that is.

Actually Fire, if it wasn't for the atmosphere that'd happen regularly.

Well the atmosphere is here so that's a moot point huh?

Okay, which conversation am I on

And I said using a handheld weapon system not the power of gravity wells you ultranegger

Bukka did I address your point?

I'm off for the night. You lads have a good one.

no, there's really no other way to address it than you are wrong

later fag

sleep well

.22lr will not penetrate soft armor

Except for all the times it does in police service

except it doesn't?

Soft vests get shrek'd by basically everything

To the point where it's a reasonable question as to why they're produced at all

plenty of video evidence on youtube proving otherwise

lmao you mean the FMJ plinker loads firing at surplus plate?

Totally NIJ standards

think about it from a liability standpoint k?

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
