Semi-Auto Shooting @ 2000+FPS

[ldasr]

I have heard of a Semi-Auto Hand Gun that is putting out a bullet @ over 2000fps. I presume it is some small caliber rifle bullet. Does anyone know what it is? Further, I just saw a movie called WAR with Jet Li and he was shooting a semi-auto that had a shell caseing that looked necked down to a small caliber.

That would be the FN 5.7x28mm. Junk in a firefight... unless your attackers happen to be wearing body armor.

 

[PTK]

Indeed, that would be the 5.7x28, however they are NOT junk. 20 rounds (standard capacity) or 30 rounds (extended mags) of 28gr at 2050FPS or 40gr at 1700FPS will ruin someone's day.

 

[briansp82593]

doesnt the 9x25 hit those speeds too?

 

[PTK]

100gr at 1850. Problems included incredible "shock wave" when fired, cases of tendinitis, very low capacity, broken accessories (cracked comps, broken red dot sights)

Made by necking down a 10mm to 9mm, called the 9mm Dillon or 9x25mm Dillon.

Faster follow up shots, reduced (sometimes none at all) muzzle flash, and lower noise are all present in the 5.7x28.

Pretty crass words for a poster that does not have one in his 'inventory list', but does show a .22lr

Have you ever fired one of these? Have you done any research,other than reading other poster's comments on bulletin boards about this gun? Have you seen any ballistics gel tests?

Just curious

I think the .223 timbs out of a cz-52 would be over 2000 fps.

Hi Idasr,

I know this isn't what you were referring to in your original post, but for what it's worth, a number of MagSafe's SWAT, Defender and Mini-Glock loads break 2000 fps depending on the barrels they're fired from.

Keep in mind, these are ultra-light bullets (in many cases, epoxy-cored ) that I personally wouldn't touch with a 10-foot pole for self-defense applications.

Here are a few numbers to consider:

9mm 50-gr. Mini-Glock load: 2000 fps out of a 3.5" barrel (Glock 26, of course)
.38 Special 37-gr. SWAT load: 2100 fps out of a 4" barrel
.40 S&W 46-gr. SWAT load: 2100 fps out of a Glock 22's barrel
.45 ACP +P 68-gr. SUPER SWAT load: 2260 fps out of S&W 4506
.44 Magnum 55-gr. SWAT load: 2500 fps out of 5.5" barrel

Interesting, but, again, not something I could ever bring myself to trust for defensive work. I don't like feathers, no matter how fast they're traveling.

Semi-Auto Shooting @ 2000+FPS

The Kel Tec PLR pistol muzzle velocity is 2,550+ FPS and the 7.62x39 AK pistol muzzle velocity is 2,200 FPS.






And the SS195 in the FN 5.7 gives 2,000 FPS muzzle velocity.

Funny thing about the movie the OP mentioned. They continually mention that the bullet cases were titanium and the gun used looked like a Walther which I excited thought that maybe they picked up the 5.7 in their P99 platform.

 

[PedalBiker]

Please post links to results from FN 57 testing.

I don't doubt a small hole through your rib cage would ruin your day. A small hole through my foot has put a severe damper on weeks of running in times past. That doesn't help me see how effective it is.

It appears to be a bit weak to me, but just as mentioned unless you need to defeat body armor a 9mm is better.

Further, I just saw a movie called WAR with Jet Li and he was shooting a semi-auto that had a shell caseing that looked necked down to a small caliber

I wondered about this too, I paused the DVD at "just the right moment" it does indeed say 5.7mm "Titanium" on the casing...but that handgun sure didnt look like any 5.7 I have EVER seen....any thoughts from those who have seen the movie?

 

[MASTEROFMALICE]

It's nearly impossible to find but the .224 Boz moved a .224 at WELL over 2000 FPS. It's a 10mm necked down to .224" if I remember right.

 

[PTK]

With lower capacity and more flash.

If faced with lower velocity/heavier bullet and lower capacity, OR higher velocity/lighter bullet and significantly higher capacity, you already know what I'd choose for serious purposes.

But then again, I carry a 4" XD .45acp as well.

 

[Moonclip]

I consider the 5.7 "junk" also for us simple civilians since we can't have the AP ammo. W/O this ammo the concept and pricing of the guns just don't do it for me.

 

[PTK]

I still love my SBR'd PS90 and my 5.7 USG pistols. Perhaps one day SS190 will be available.

The normal ball ammo is spitzer-tipped and will go through II and IIa armor. Apparently it has problems at IIIa. Even the AP ammo which will go through IIIa won't go through hard armor.

That would be the FN 5.7x28mm. Junk in a firefight... unless your attackers happen to be wearing body armor.

No, if they were junk then they would still be junk. Just because a bad guy is wearing body armor does not make the gun more effective than if used against a bad guy without body armor.

2000 fps is easy to do with a 44 mag and 180/200 grain bullets.

I know, its not as KeWL as a semiauto when you hold it sideways, but you also don't have worry about those pesky hot cases going into your bra, and producing a third nipple

Yeah, I guess you could say that. The reason I don't have one in my "Inventory" list is because the round is nearly worthless against soft targets. Unless you understand that two of my very good friends purchased FN 5.7's and both sold them. The round is not worth it in a firefight unless your attackers are wearing body armor. It just doesn't do enough damage on a soft target. It wasn't designed to and therefore doesn't. I have fired them multiple times as I was intending on purchasing one. Yes, I have seen the tests. Extreme over penetration is what the ballistics gel tests show.

Wow, you label my words as crass. Why does it matter if I own a .22lr? I don't carry it and it is used mainly for plinking so I can put down hours and hours of trigger control practice and moving while shooting practice.

I guess you could be pointing out the fact that the 5.7 could be just used for practice but that would be a horrible financial decision as the ammo is extremely expensive.

 

[vanilla_gorilla]

Meh. Without AP ammo, it's a glorified .22 Magnum. For self defense, I'd suggest sticking to something starting in the .35 caliber range.

 

[PTK]

Odd. Every single test I've seen with SS195 and SS197 (the only two rounds civilians have access to) show quite different results. SS197 goes in a few inches and mushrooms, continuing onward to anywhere from 6 to 10 inches before fragmenting, and SS195 tends to yaw after two to three inches, then continues to between 6 and 14 inches.

AP Ammo

Thanks for all the info. What is AP Ammo? Of all the 2000+fps mentioned it seems only the 5.7 will puncture body armor?

Ap Is Armor Piercing

AP ammo is ARMOR PIERCING. It usually has a steel point and will not expand. It is great for targets with body armor, but usually comes up short in the stopping power if you are not using rifle ammo.

About 20 years ago a gun writer article in Guns & Ammo Magazine,
the base gun was a Colt Commander in .38 Super. Barrel by Bar-Sto
and the .38 Super was necked down to .22 & it did break 2,000 FPS

Anybbody else recall this article?

Really?
