| What exactly is a FN 5.7? Ive heard alot of talk about them and dont know what they are exactly? |
|
Where are you guys getting your non-information? the five-seven and the P90 will fire this round. The Five-Seven is being sold as two different models, one having a straightened trigger guard which is probably what the complaints are centered around. The magazines are 20 rounds. 20 rounds of varmint killers? No, 20 rounds that will penetrate PASGT at 300yds and will also penetrate bp vests with ease. The P90 has a 10.5" or so barrel, 50 rounds, very light and very compact. You think it is a piece of shit? They will be selling the P90 in the US next year- maybe as an SBR or even with a lengthened barrel/fake suppressor like a lot of the bobcat H&K's. A 5.7x28mm upper wouldn't be hard to do but I don't think anyone wants to. The round works great in the P90 and the five-seven, why try to shoot it from a rifle? Neither may be great guns, but, I don't see any of you actuallly knowing anything about what you are saying. Squirrel gun? That's a very stupid comment. You are obviously commenting because of the size- in this case, it doesn't really mean anything. Think about the size of your AR round compared to the millions and millions of rifles in larger and more powerful calibers. Do you think that a "cut" 5.56 cartride would contain half as much powder? as far as I know, there is filler in the gunpowder in a lot of ammunition. maybe there's just less FILLER in these. The pistol would be a great investment. Anyone looking to drop $850 on a second or third RRA, you'd be better off buying the pistol and some ammunition. $800 on gunbroker with 3x20 round magazines. ammo is about 60-75 cents per round. hmmm.... must be garbage--- oh, odn't lecture me on "just because it's more expensive doesn't mean it's any better" |
The 5.7 has nowhere near the velocity or wound potential the 5.56 NATO has. remember that the 5.56 requires velocity to be affectiv, as in fragmentation. The 5.7 fires a much lighter bullet(around 30 grains I think) way below the the fragmentation threshold of the 5.56 which should apply to the 5.7 as well. The velocity of the 5.7( around 2000-2200fps) is not even above the fragmentation threshold for the heavier OTMs. The velocity dropping below the fragmentation threshold is why the 5.56 is so ineffective out of short barreled carbines and the 5.7 would be even more so. I have no idea what the filler you're talking about is; but only so much powder can fit in a modern case without dangerously raising chamber pressure. so I dont bellieve that there is a possibility of the 5.7 getting anywhere close to the 5.56 in terms of velocity or damage Also the shorter 5.7X28 case holds much less magic than the 5.56X45

I'm defending this cartridge or giving a reason it might be nice to have. if you want to dispute the details of what i've said, go find something better to do. i don't want to hear what you believe to be true or what you think is true. I guess I have to proofread everything I type. Any one small idea that I don't phrase right is just more for you to try to dispute. I agree, it's not an AR, but is that important? it's definitely not a peeshooter like people have been implying. "lighter bullet(around 30 grains I think) " your thoughts "I have no idea what the filler you're talking about is" you don't, so what? "so I dont bellieve that there is a possibility" you don't believe... "Also the shorter 5.7X28 case holds much less magic than the 5.56X45" yeah, but it holds a smaller lighter bullet. what do you think fills that space? "Standart pistols and SMGs chambered for pistol rounds were proved ineffective against enemy soldiers, wearing armour (bulletproof) vests, so FN Herstal developed a new round with enhanced penetration - the SS190. This round looks like scaled downt 5.56mm NATO round and forces the pointed, steel core bullet to the 600-700 meters per second at the muzzle, thus being capable to defeat standart CRISAT helmets and armour vests at reasonable distances (50-100 meters)." "gramm (31 grains) pointed steel and alluminium core bullet to the muzzle velocity of 650 meters per second (ca. 2130 fps) from the pistol barrel. " "The Five-seveN is advertised as being capable to penetrate standart PAGST vest at 300 meters and standart CRISAT (kevlar + titanium) vest at 100 meters." I think this, I think that, I think this, I think that.... |

Im not saying the 5.7 doesnt have its place,Im just saying its nowhere near as effective as the 5.56X45 or many common pistol loads also its not what I believe, Its facts; try reading the www.ammo-oracle.com/ there's a reason short barrled 5.56 carbines are so inefective, there lacking in velocity; just like the 5.7. Yes it can penetrate armor but the terminal effects are lacking, even without armor. I didnt mean for you to take my post wrong, I was just commenting on what I thought were inconsistancies in you post |

The P90 and the Five Seven were designed as PDW and sidearm, respectively. For use up close and personal, against body armored enemy troops, by personel not normally armed with a rifle, Officers and support types. Much like the M-1 Carbine of 60+ years ago was intended. No, it won't replace an M-16 type, but it was never designed to. Even an Armchair Commando, like myself, can see the reasoning behind that one.  Lonny P.S. IBTL (Though the thread HAS moved somewhat to AR related.) |
well, if you don't like the fact that i like the cartridge, or at least understand it's value, then listen to what you preach- who gives a shit what other people think.[/] instead of bitching about my liking the cartridge, go spend your time elsewhere. if you think i'm lame to come in here to defend it, you are twice as foolish for trying to tell me i don't belong here. btw- i do take out my guns and shoot them. when i'm not, i like to visit AR15.com and that's what i'm doing. i guess the rule is, if i like something, i ought to be out doing it so as to not upset you ? You are basically the pot calling the kettle black. Get a life. 223-4me- i see what you are saying and i guess i did take you wrong. i apologize. |

FWIW - I've never used my 5.7 on any armor, but on small soft targets (opposums, coons, wild dogs) it works wonders. One shot one kill. For further FWIW - my 16" & 20" AR won't usually drop a dog with one shot. I'll try to do a box o truth style test on it when i'm feeling better and see what all I come up with ETA: I'm still IBTL |
JosephR, V-A-L-I-U-M, get some!  Seriously, you seem a tad touchy! I like the weapons and think they have their place. For the record, quoting all the technical specs on the SS190 round doesn't do much as that round wont be available to civies. No knocking the round, just saying that the round we can purchase is a tad different than what the weapons were designed for. As to civie P90: yes it will have a 16" barrel on it. I forget where the thread is, but if you do a search it will come up. There are actually pictures of both the P90 and F2000 (I think that's right?). If you like the 5-7 round go for the P90, if you like the 223, go for the F2000. Either way, if I have more money than I know what to do with I'll have all three!
