to both penetrate soft body armor, and deliver adequate stopping power. Hell, 460 will get 80 gr prefrag to 2200 fps, in a 5" barrel, and the .45 has 4x the frontal area of a .22.

Jeff has said a shorty 223 is a "poodle shooter". Well,it's got more power left at 250 m than the .22 pistol load he said would be adquate at 10m and less. Shows how much "combat-experience "helps one think properly about shooting, guns, ammo, etc, I'd say.

Glad you have enough comprehension to post this in a black powder forum. fftopic:

:devil:

Frotal area is what stops a slug in a ballistic vest, thats why slugs stop, but a ice pick slides in. A .22 lr because of the small frontal area will penetrate a lot of vests, bot larger slugs do not.
P.S. This is a "Black powder forum" not the wildcat forum.

Hey this is great info! I didn't know a blackpowder-loaded rimfire could go through body armor! Man what a great post!

 

[RIKA]

Great imagination Melvin. Just the historically important black powder pronouncement we were all waiting for.

no .22's dont penetrate vests. Not even the "solid" .22 mag rimfire will do so, from a rifle barrel, Threat level II or better vest. A mere 3-4 layers of Kevlar stops .22 pistol bullets, and only 2-3 layers more are needed to stop .22 rifle bullets. A level II vest has 18 layers.

A .22 HORNET rifle, or say, 10" Contender, will penetrate a vest, out to whatever range it drops below 2100 fps (or thereabouts) With the old styled, blunt hp-sp type of Hornet bullet, that range would be very short with the Contender, probably inside 50m, and probably inside 100m, with most of the short barreled (20") Hornet rifles.

You have obviusly never heard of liquid body armor

 

[andy]

if it won't evenstop a .22, what good is it? I've heard of the crap, and until it's in WIDE circulation, it's irrelevant, just like all the crap u post about.

 

[Hard Ball]

"If it won't evenstop a .22, what good is it?"

It stops a hell of a lot more than .22s as you would know if you had really herad of it. You seem to know very little about body armor.

 

[TODD 3465]

What he knows is 20+ years out of date, it seems.~>;-)

 

[andy]

the point IS, stupid, that since such armor AINT commonly worn, it's IRRELEVANT, just like all your other commentary is.

 

[TODD 3465]

Some dipstick better take a look at how quick modern Interceptor vests and other similar ones move on places like Ebay.~>;-)

Well andy you really seem to know whats going on with aramid fabrics. I would inquire as to what type of Kevlar you are refering to in the above quote? What I mean by this is.

(1) Thread count per centimeter or inch in both warp and weft yarns.
(2) Tensile strength in newtons per milimeter or pounds per inch of width
(3) Pre tension amounts per yarn during looming(weaving)
(4) Thermal or non thermal set during finishing.
(5) Are there crossed linked intermediate layers between the arimid fabrics.?
(6)Type of yarns are they spun type or of S&Z construction.?

I could go on and on with questions but having you answer these will give me something new and will lead to more questions.


Ahhh the quest for knowledge ain't it grand?

 

[TODD 3465]

'cept andy is still at the quest for fire level.

 

[andy]

doesn't matter, since .22 mag doesn't penetrate

ANY decently made Threat level II Kevlar vests.It's when they started trying to use lighter, cheaper crap like Spectra that the armor makers got into trouble.

 

[mrostov]

Interceptor with SAPI has been proven to stop close range 7.62x39mm hits. A report by the USMC from the fighting in Iraq referred to SAPI as, "God's gift to the Marines."

 

[andy]

it remains to be seen how LONG such a vest remains

viable, under what conditions. Kevlar is well proven, as long as it's not exposed to too much moisture or sunlight, for about 10 years.

 

[andy]

Not many want to spend $500-$1000 on armor

that is likely or even MIGHT be pretty worthless in 2-3 years.

What is this doing in a black powder Forum? you better lay off overdoing those meds.
