 New 5.56 bullet designed to split into two bullets? Secret army tech?

Here is the cliche start to my question.

My neighbor, navy guy, whose brother use to be a Ranger (just got out a few months ago) says that the army is or is going to be fielding a new round for the M4.

Something along the lines of a bullet that upon impact splits into multiple pieces or something to that effect?

I smell BS, google didnt help much.

Am I wrong or is there some new 5.56 projectile I havent heard about?

Aside from the M855A1 "Enhanced Performance Round," no. It's a lead-free version of M855 that runs at higher pressure and velocity, and the different bullet construction might cause the "splits in 2" story...

Is this different from fragmentation?

M193 splits into different pieces upon impact.

From the muddled information I was given, it was made to sound like the bullet split into two separate pieces. Not just typical fragmentation.

Hell if I know.

Shot a buncha surplus ( Centurion, and some malaysian as well )M193 at 5 gallon bucket of ice. recovered a lot of "Halves" .
They break up when they hit something hard.

fragmentation is cool

on an unrelated note, doubletap makes an insanely retarded round that uses two projectiles in a cartridge

A centerfire rifle or pistol cartridge with more than one bullet will mean lighter bullets. That means less penetration through cover/concealement and any bodyarmor the target might be wearing. Better to go with controlled pairs IMO.

M855 has always broken into pieces, usually three, within a certain velocity envelope.

The new enhanced "Green" update does the same.

That looks like Elite Ammo projectiles.

They had them for several firearms until the Feds showed up.

I was really looking forward to their 6.8 stuff. It was testing out great.

The ones I saw looked a LITTLE different, looked like they would break in two pieces rather than three, and they had a lot more material machined out.

A lot of 5.56 already does this in a way

I got some of it out here in AFG, very classified shit. Top half of the bullet kills women, bottom half goes for children.

Isn't that what 5.45 was supposed to do initially??? A holow in the interior of bullet causes crimp or breakage of the bullet.

What happen to metal powder bullets? The ones that were supposed to explode on soft surface and solidify versus harder surfaces???

These seemed like a fragmenting armor peircing type deal. But Im not sure.

He's talking about M855A1. It has an exposed steel tip, which will break away from the rear portion of the bullet after impact.

Wow, how much do those cost?

Elite ammo was using Barnes projectiles and turning them down for some of their stuff, while others happened to have the "wrong" metallic content and were considered by the ATF as armor piercing since they were also "CAPABLE" of being chambered in a pistol.

The Feds seized the inventory.

Bunch of over reaching government bullshit as usual. They were showing great promise. Being turned projectiles they were very, very, concentric and almost no variance in weight from one to the next. Very consistent. Very accurate.

It's all hype. There's no way to shoot a Glock through a barrel with any kind of reliable accuracy.

It's the 855A1, like they said...

But wouldn't it be cool if they were (re)introducing SLAP rounds in other calibers?

A bit of a stretch, but nonetheless.

These ones are heat seeking and will chase the jet engine exhaust.

I'm going to verify this with the guy running the range or working behind the counter at Walmart. If it weren't for them I would have never known a 5.56 tumbles as it exists the barrel.

I think Mk318 is also a "two part" round. First half is the fragmenting porton last half is a solid copper penetrator.

You may want to look up "wound patterns 5.56mm" on the interweb thing, there are some rounds in 5.56 that tend to break into two parts upon impact. It looks like the new 5.56 77gr. round may be one of them along with M855 and M193.
