They were made for the military for survival purposes, called the M24.

 

Cool....I want some of these....I always wondered why there arent any .22lr FMJ hyper veolcitys.
- Would be a good idea if they were available for the puplic.

Just imagine a 40grain pointet FMJ .22LR @ 1400fp/s .:t

..purpose...

Purpose is better penetration so you can hunt bigger animals (Head shot)

 

I've only seen FMJs for .17HMRs and .22WMRs. Does anyone make them for the .22LR? What is their purpose exactly?

I've seen one or two references to them, nothing real positive. The heeled design (reduced diameter to the rear - to fit in the case, which is the same OD as the main bullet) doesn't lend itself real well to being accurate, or easy to make. The soft lead bullets are also smaller to the rear, but this "skirt" reexpands to fit the bore once it's clear of the case mouth.

 

The law enforcement community does not want to see full metal jacket bullets. Ballistic vests have a hard time stopping regular .22 lead projectiles.

That makes zero sence at all, i dont see how a vest they wear would have trouble stopping a 22lr bullet and stops them from 9mm's and .45's just fine. I dont see how they dont like FMJ's either, when its what the mass majority of people shoot. You may be thinking of steel core ammo as in SS109 military grade ammo...

From a pistol? I'd change vest suppliers then. Vests (without hard trauma plates) are only intended to stop pistol rounds. Regular 22 lead slugs, even from a rifle are fairly easy to stop. I'm not aware of any vest that has a problem doing so. Now the 17s from rifle length barrels are a bit tougher, and a few 22 mags will do it, but then again this is from rifle length barrels.

 

The newer vests will stop 22 rimfire from a rifle. The older vests will stop 9mm-45 caliber but not all 22 caliber offering. I have seen vests that have been tested. I sometimes wear a vest while on duty. My older vest was not rated to stop 22 rimfire from a rifle. I would think a full metal jacket would shoot thru my new vest.

 

What? Vests dont always stop .22lr with less sectional density than 9mm with much more SD? With equal velocity?

How could that be possible.

 

Imagine a soccer net (the vest) if you kick a soccer ball at high speeds the net will "catch" it, however, if you so much as toss a marble (with less velocity and mass then a soccer ball) it will go right through the net.
If they are afraid of 22rimfire FMJ what about 204 and 17 centerfire rifles

well that is why you have your level I,II,III, IV vest with different size trauma plates 10x12 ceramics can stop a high power rifle 7.62x39, .223, depends on the vest level and trauma plate size and level. The Police dept. usually get level III vests that will stop a 44 magnum but not a .223 bullet, they usually get soft trauma plates 5x8 and some reinforce it with a steel plate, but still its not like the military issue vests. Some reporters during a crisis situations use better vests that the police dept. usually vests range from $250-1800 depending on brand and level plus you have to get your trauma plates. Oh and another thing vests don't last forever they have an expiration date, usually the PD will issue new ones every 2-3 years, the reason why is that the kevlar and other fibers inside the vest pads get weak if exposed to moisture and the elements, so lets say no bullets have touched the vest but during duty some thug stabs you that will expose the fibers, wear and use might open a seam, etc. just my .02 cents (my father sells vests)

 

I've seen 22lr rounds from a pistol zip through 4 layers of kevlar, but doesn't a level !!A vest have like 12 layers? Still, thats why we can no longer buy the original Glaser black tip ammo, it would defeat some vests also.

 

vest are rated by velocity, not caliber..

Correct, actually the soccer net analogy isn't all that far off. I have seen my share of kevlar vests that have been stabbed through by low velocity knives.

 

Thats because kevlar is high tensile(knife stab), low hardness. IE, a diamond will scrach steel ( hardness) but a diamond wont stretch or deform, or carry much load -it shatters (low tensile strength). Kevlar can be "cut" with a substance not much harder then a finger nail, yet can "hold" off something with great energy!

Took my old vest to the range........Hung it over 3/8" plywood..........Shot it numerous times w/ .44 mag 310 cast lineotype..........did not penetrate it.......shot it numerous times w/ .35 remington 220 gr from a rifle...........did not petetrate it.............numerous (hundreds) of times w/ .22 lr.........did not penetrate it.
Shot it w/ 223 .......went through it like a hot knife through butter
Shot it w/ 45-70.......same thing
When hit w/ the .44 it pushed a hunk of the vest through the plywood the size of a fist. It may stop the bullet but your chest won't stop the vest ! Thats why they make trauma plates.........Shot a trauma plate w/ 12 ga slug, looked like an ash tray after.

 

The trauma plate or the slug

very interesting win70..... i love to read proof tests like those!!

 

I just got a new digital camera. When my Son comes home from school I'll have him set it to to the computer (caus I'm a moron) when it comes to such things. Then I'll post pics of the bullets.

 

IIRC the fmj round was used with the Hi-Standard silenced pistol during WWII by the OSS, as per the Geneva convention they could not use the standard .22lr with the lead exposed.
A standard unjacketed bullet was not p.c. at that time.

 

Will any but the ceramic plate stop an arrow? What if the bad guys start usin' Muzzies? Icepicks? Pitchforks?

 

A cop has a gun, wont work to well on their (Bg) behalf!

I remember reading in one of pseudo-military magazines years ago an article on Fighting Knives. It was basically talking about the weakness of daggers, especially the Fairbairn knife. The writer claimed that a Bowie type blade like a Ka-bar or a katana blade was superior as they were for slashing as opposed to stabbing.
My point is, the writer backed his argument by talking of tests on vests in which the vest would stop thrusting blades but the Kevlar fiber would give up the ghost when slashed. The fiber would “catch” all but the very tip of the point of a dagger, like the soccer net analogy but a cutting edge would slice right thru
Also, a cop told me if faced by an opponent who appeared to be wearing a vest they were instructed to, if armed with their sidearm, try for a headshot or, better yet use the riot gun. Even if the slug or buckshot didn’t penetrate the vest, the striking energy would incapacitate the threat.
As far as the whys of no FMJ .22 LR, probably the previous post of the difficulty of manufacturing a heeled FMJ & also a limited market for the product.

Try a 17HMR FMJ.

 

I haven't tried that (don't have a 17). Will it go through ?

I have heard that it does so very well as it slips right through the weave. I have no personal experience.
