The gentleman in the post is talking about full auto fire as well A full auto 22lr will "tear somebody up pretty well" too I could dig up lots of posts ...way more than 15 of people dropping to full auto fire from an MP-5 |

Lessee...going by World.Guns.Ru's ammo ballistics table...
.22 WMR (FMJ) gets you a 300 m/s, 2.6g round. 5.7x28 (FMJ) gets you a 750 m/s, 2g round. I'm thoroughly unconvinced by the "it's only got the stopping power of a .22WMR" argument just going by numbers and penetration behaviors. Both are known to not overpenetrate. Running some physics numbers, the 5.7mm round gets about twice (1.92x) the momentum and almost five times (4.8x) the kinetic energy. This is reflected by their ballistic gel performance. Theoretically, the 5.7mm is a much more lethal round than the .22WMR. For that matter, it's vaguely close to a 9mm JHP (assuming 5.72g and 458 m/s) in energy delivery, with a little over half (57%) the momentum (the reason behind its high controllability despite high ROF in the relatively lightweight P90) and 93.8% of the kinetic energy. So theoretically, it has kill capability closer to 9mm than .22WMR. Also, there have been 15 recorded shoots with P90s, as opposed to A Bunch™ of shoots with various 9mm SMGs (including MP5s). So that particular statistic isn't really usable, although for what it's worth, all of the said shoots involved single shots or short bursts. Given, they were conducted by special operators (better shot placement), but it's still suggestive of a successful design. |

I'll take this even further and discuss another quote of Doc GKR's: Quote:

#2. These weapons are in use with dozens of PD's and have been for some time. They are pleased with them. They work very well for them. So the weapon is not ill-suited for LE work. Quote:

The 5.7mm ball produces a wound cavity about the size and shape of the best 9mm 115 grain JHP +P+, except the peak occurs at a deeper penetration. And more from the same officer: When I talk to operators from other agencies about weapons, I now seldom have to explain what weapon I’m talking about when I mention the P90 as my primary. Obviously the folks at FN are getting the message out and the weapon is now familiar. If you operate in an environment like the one I operate in, you can’t go wrong with a P90 slung at the low-ready. -DmL |

Yes, and I have heard some less flattering quotes from Mr. Wall from people that actually know him and worked with him while they were evaluating the p90.
And I have seen you run this discussions into the ground on too many different boards to want to watch this In fact...a check of your posts on TFL shows you pretty much joined to discuss this weapon system almost exclusively. How is your FN stock doing anyway??? Later |

And I joined the board because I was looking for info about Desert Eagles. What's your point?
Keep the ad hominem stowed, it's not relevant. What's your agenda for disliking the P90 concept and system so much? |

Why are you so against these weapons? Trying to save people from having to trust their lives with such an ineffective round? A round so "ineffective" its in general use in 30 countries with the elite (French GIGN) and has yet to be responsible for the injury of any people using it over the past decade? You are correct that when I discuss something here, it is most often these weapons. But that is when I discuss. I read about many subjects. -DmL Last edited by DmL5; March 30, 2005 at 05:57 PM. |

I think I'm going to buy a Kimber .17 MACH 2 Target for a Defensive carry gun.
.17 caliber bullet, 17 grains, 1600+fps. Got to be the latest thing in CCW! |

You know, the SS190 and associated rounds were designed to be combat effective. I dunno about .17WMR.
Have there been any human shootings with .17 yet? |

More info I have gleaned on 5.7. This is based on magazine writers, but I don't have the access I used to have regarding such matters. David Fortier: "Developed as a NATO replacement for 9x19, this cartridge currently languishes in limbo. While it has successfully met all NATO criteria for PDW, Germany blocks its adoption. While it was adopted by a number of European SF and the U.S. Secret Service, many vocal detractors doubt it provides adequate terminal performance. It will be interesting to see what, if anything, the future holds for this tiny cartridge." "It should be understood from the outset that this new PDW was intended to be just that, merely a defensive weapon. It was intended to be issued only to personnel who did not need a regular assault rifle(truck drivers, maintainence personnel, etc.), but still need a weapon to protect themselves. While the P90 was intended to be a PDW, some are pushing it for other, more offensive missions." "Currently, there have not been enough actual shootings with this combination to clearly define performance. It was used in the well-known Lima, Peru Embassy incident. In another well-known incident, Houston PD SWAT responded to a man firing an AR15. He was killed by a shot in the chest attributed to the P90, although several shots were also fired by 5.56 weapons. I am also privy to an incident in Iraq where an American soldier was hit with a 5.7x28 round fired from a P90 during a certain raid. Hit in the hip region, he dropped instantly and tumbled down a flight of stairs. It should be kept in mind, though, that a hit in this region with most any caliber would likely have had the same effect." "Would I rather have the P90 SMG than a 9x19 handgun loade with ball if there was the chance I would be attacked by assault-rifle-armed and body-armor-clad hostiles? Yes: Poor terminal performance at 900rpm is better than rounds failing to penetrate." "The P90 is a PDW. Nothing more." Guys, I know it isn't very sexy to think of your prized toy as being designed for truck drivers, mechanics, and clerks. But it was. |

I think your second-to-last quote shows a sort of anti-bias, either way.
He suggests that even if it really is as ineffective as everyone likes to say it is, he'd still rather have it, simply because it's putting out so many bullets and getting them through the opponent's armor. Quote:
As for FN's 5.7mm system being chosen over HK's 4.6mm system, well, I'd like to see a source. In terms of straight ballistics numbers, the 4.6 comes out slightly ahead on energy delivery (if HKPro's numbers are to be trusted), although it seems like the P90 is a more ergonomic setup than the MP7. Also, it would make sense for Germany to not adopt the P90 for its general-issue PDW if they have the homemade MP7. |

Whether Fortier used any of your posts for info, I do not know. How long have you been posting on the 5.7? As someone who has had articles published for "entertainment", I know that sometimes articles languish in the editor's hands for quite a while, and sometimes they barely squeek past the deadline. I really have no idea when he wrote the article. It was published in the Guns & Ammo "Combat Arms" special edition last month. He could have written it a few weeks or several months ago.
Quote:
I ask again, with 30 coutries and more than a decade in service, why all the trouble finding documented shooting reports on this cartridge? It would be roughly the same age as .40S&W and there are numerous actual shootings on record with this round. Just a thought, but because you let something "slip" on the internet, doesn't mean you are the only one with such info, and it wasn't told elsewhere. Myself, I've become jaded by most gunwriters. But there are still some who are generally reliable and tell the truth. Mr. Fortier seems to be accurate on the details of the weapons systems and operations he writes about. |

"Houston PD shot a subject who was firing at them with an AR-15" "Houston PD SWAT responded to a man firing an AR15" Quite a surprise for me, and I'm glad you posted it. -DmL |

Mr. Fortier wrote the article after a visit to FN-Herstal in Belgium, at the invitation of Phillipe Claessens, whom he identifies a the firm's general director.
After an extensive tour, where he got to watch P90 production and talk with the workers, he then got to watch the P90 put through its paces. Then he got some trigger time with the system himself. Speculation on my part, but sometimes individuals share "inside" knowledge, especially with those who have the proper credentials. Mr. Fortiers' are easier to verify than anonymous internet posters. |

1#. The only shootings he knew of were those I posted. If he asked FN they wouldn't have mentioned 2 shootings, when there have been well over a dozen in the US alone. 2#. Similarities in wording. 3#. The only shootings he mentioned were commonly-known ones, as he said. And I'm sure he didn't get the Iraq shooting info from FN. -DmL |
