Well, thanx Savage, and, yes I do.
I like mine very well. It is a real joy too shoot and accurate. It is a good pistol too learn on--it gives some loudness that is needed to get use too without a lot of recoil.
There are a couple of concerns with the caliber though. Most ammo available is not the best for self protection and use in a home might be best too consider another caliber for penetration concerns. The little sucker will penetrate with the best.
The cost of the ammo is a major concern---well, for me---the last I checked it was $20 a box and that is the stuff that is not the best.
It is a good plinker though. It would be fun too burn a brick or two on a high bluff over a river. The carry accuracy is good enough that it outdoes a .22 in a pistol, accuracy wise and range wise.
I will not sell mine.
Blessings

Many moons ago, I was looking at some .30 Mauser rounds and thought "that would be a cool wildcat if necked down to .22 caliber". That is more or less what FN has done in the 5.7x28 but velocities are not up to what I would have expected as a top of the head guess. The ballistics from a 5" barrel seem pretty close to the .22 WMR from a rifle, not that it is such a bad thing. My 6" AMT Automag ll for the .22WMR gets up to 1800fps with CCI 30 grain TNTs and that little auto has become my favorite handgun for hiking and small game hunting. The 5.7 does beat that by a bit but not really enough to make a difference in the field and with the .22WMR I don't have to crawl around in the cactus and sagebrush to recover brass.

coyotejoe - didya know that Ron Reed, this sites moderator, makes ammunition and that he necked down a 7.62x25mm round to take a 22 caliber slug?

? Get up onto his site and check out his offerings. Mikey.

coyotejoe · « **Reply #5 on:** July 06, 2008, 02:46:07 AM »

Thanks Mikey, I did check out his site and see the .22 Reed Express listed but with no real ballistic data.

Some folks in a local GShop were claiming their 5.7 was way faster than 2000 fps or so.. more like 28 2900.. I did not go check on it but made a mental note to do so.. the round was also said to not stop in kevlar jacket material due to the extreme speed and small diameter.. I wonder if it will be attacked by the bad politicians that want to ban us having such a capability... ??
As to the 22 wmr... love that cartridge and that is very good speed out of that amt.... I wished I still had mine... the 22 mag kills small game like nothing I have seen before, having been a 22 long rifle fan for a long time. the .204 and the 17 cals. put a real hurting on varmints, but the cost is also a bit high for my tastes... but they work.. of course the 204 is in a league of its own.. like I would imagine the 22 reeder would perform, I guess... I got one of the 204s and it is a barn burner... do not shoot anything you would like to eat and do not intend to pick up with a strainer or a garden rake... it makes a bit of a mess... the 17 tears a terrible hole in rabbits and such and the speed is incredible in the centerfire version... noticeably faster than my 22 mags when I shoot at moving vermin far away... it is almost instantly arriving there with great aplomb...
bang for buck I like the 22 mag, but the fair comparison is the 5.7 compared to the other centerfire speed demons that can be chambered in a handgun for hunting... the 17 rim and 17 centerfire can be stuffed in a centerfire pistol, and that is all I know about... the 5.7 I saw was in an auto format and it held a ton of ammo, by the way... I found that incredible ...
if the speeds would be as fast as I thought they were, then it could be a great, lite, multi-round semi auto with great range and magazine capacity, like for two legged coyotes, and such when hiking, camping, etc... I would not use it in the house either...

I haven't come across a listed factory velocity but went to "Ammo Guide Interactive" where a few handloads were listed. The highest velocity there was a 33 grain Speer bullet at 2090 fps. That equates to 320 ft lb and is in the same speed league with the old .22 jet. I guess that shouldn't be surprising since the .22 Jet has quite a bit more powder capacity. Even the much larger .223 only does about 2100 fps from a 10" barreled pistol, although with a heavier 55 grain bullet.

OOPS, I did find a listing of a 28 grain bullet at 2550 fps, 404 ft.lb. but that velocity was from the PS90 carbine with 16" barrel. From a 5" pistol you're back to maybe 2100 and a 28 grain bullet sure wouldn't have much sectional density.

After re-reading my first post I realized that I may have given the impression that the 5.7 is a necked down 7.62x25, well it isn't. The 5.7x28 is an entirely new cartridge of much smaller base diameter. Considering the small powder capacity I guess it is surprising it hits the speeds it does and that seems to be around 2000 fps from the 5" barrel.

I was listening to the police scanner Friday night and there was a call to a slummy apartment complex a few blocks away for gunfire from an sks. As more officers arrived, they found FN 5.7 shell casings and made a point to announce it over the radio. It sounded like they were a little spooked. So who knows what it actually does to body armor/barricades.

After chasing some folks through some apartment complexes, an individual was arrested with an FN 5.7. They ran the serial numbers over the radio and they came back clear. I know that doesn't totally make the weapon clean, but it's not a $75 Saturday night special. Apparently someone spent about 2 month's worth of rent on it.

Mikey · « **Reply #9 on:** July 14, 2008, 12:43:12 AM »

When the cartridge first came out I considered it a pistol sized version of the 223 with velocites between 2000 and 2100'/sec from the handgun, possibly a bit better from the carbine. It has penetrability but it sure ain't the 7.62x25mm for penetration.

I would have loved it if it had been a necked down version of the 7.62x25 or a commercial version of Ron Reed's development, but alas.

As ya know, the 5.7 started life as a police/military round and was touted to be capable of penetrating body armor, destroying barricades, causing police cars to explode and making muslems pray to allah, which also leave the cowling masses to fear for their lives and to flee madly into the streets to avoid the deadly barrage of armor piercing, house busting bullets.

This cartridge is so terribly devastating that to even hold one in your hand is flouting with instant death, which is why the last time I walked into a cop shop to ask about the round and pistol I was told that it was availble ONLY to police officers in neu yawk state, and then only to those officers who have had deadly device twaining.

Whew, sure glad I didn't detonate myself er sumptin. But, at least I know where they are located and who sells them so in case of insurrection the place can be set on fire 'cause Lawd knows we sure don't want any of that overly destructive police stuff floatin' around the general population during troubled times.

Me, I'll just stick with my old Tokarev................ Mikey.

I once had a cop go ballistic on me when I showed him some 9mm Aguila "IQ" rounds I had purchased for a defence load. "That's the round that penetrates body armor, why do you want a round that penetrates armor?" It seems to me that many cops are quite paranoid, even though statistically their job is much safer than farm work, construction work, mining, truck driving and about fifty other common occupations, some of which are up to twenty times more dangerous than law enforcement. That is not to say there aren't some places where it is dangerous to be a cop, but outside those inner city danger zones a cop is more likely to be struck by lightning than by bullets.

Here is Texas, you can go to Bass Pro Shops and buy one for like $700.

I have a death wish---but I still enjoy shooting mine more than a .22.

The latest Women and Guns just came out with an article about the five-seven. It's worth the read. Mikey.

williamlayton · « **Reply #14 on:** July 20, 2008, 03:48:45 PM »

Does it have pictures of the wimmen?

Mikey · « **Reply #15 on:** July 21, 2008, 01:01:49 AM »

Yes William, it has pictures of the wimmens; and they are pictures of happy, smiling wimmens shootin' at pictures of their husbands..................I'm sure they could use a few more targets..........(lolololol).................

williamlayton · « **Reply #16 on:** July 24, 2008, 01:04:19 AM »

Thank you Mikey but my wife just informed me she doesn't need a picture target when she has the real thing.
She also added she would take her chances with a jury--and, not a jury in Texas, by God would convict.
In hindsight, I must agree with her conclusions. YUP, by golly.

I didn't know that a rimless .22 Hornet could be so fearful. Maybe I'll trade my .44 magnum in for one.

coyotejoe · « **Reply #18 on:** July 24, 2008, 04:14:30 AM »

I believe the Hornet beats it by quite a bit, driving 45 grain bullets a couple of hundred fps faster than the 5.7's 28 grain pills. It's really just a tad hotter than the .22 WMR. In my AMT auto I have clocked the CCI 30 grain TNTs at just over 1800 fps from its 6" barrel versus the 5.7 just over 2000 fps with the 28 grain bullet from a 5" barrel. I doubt the extra 200 fps would make a great deal of difference. The armor piercing qualities of the 5.7 have more to do with the bullet design than the velocity.

woodchukhntr · « **Reply #19 on:** July 24, 2008, 07:03:59 AM »

I saw somewhere that the armor piercing bullets are not available to civilians. I wonder if they are on the black market yet, so only the bad guys will have them?

coyotejoe · « **Reply #20 on:** July 25, 2008, 03:14:33 AM »

I can't say, since I don't have a lot of black market connections, but that sounds about right.
