327 or 5.7 x28 what is you choice

.327 and...

I havent used any ,327s. It is probably as good a choice, at least, as the 5.7X28. As a shooter who handloads, the ,327 is an easier cartridge to deal with.
That being said, I do own an FN FiveSeven pistol. It is a fullsized gun - though lightweight and easy to handle.
There are misconceptions about the 5.7X28 that bear some clearing up.
its a glorified 22mag and not worth it if you ask me. Get a kel-tec PMR-30 if you want something like the 5.7 but its way cheaper and holds 30 rounds of 22mag!
That is misleading. The comparison that we hear about balliistic simllarites compares .22 Magnum ballistics as it is fired from a rifle to the 5.7 baliistics from a pistol.Try putting a .22 rifle under your sweater. Fired from a pistol, the .22 magnum falls way behind the 5.7. Ammo is not hard to find.

I would go with the 5.7, I would feel more comfortable with the amount of recoil and the 20 rounds in the mag vs 6 or 7 with a revolver. I would want to see wall penetration data also, but I feel like the 5.7 would go through fewer walls, but Im really not sure.
 
.327

IIRC, that 5.7 was developed so a lightweight PDW for the military could defeat soft body armor..... that bullet is not available to most of us, so why use a round designed for a specialized platform most of us won't ever have, and if we did, we couldn't get the bullet designed to make the whole thing worthwhile?

.327 mag: .357 energy levels in a 6 shot j-frame sized gun. Yeah, I want that.
 
It was designed to defeat body armor when fired out of the PDW system it was designed for.... I doubt if that short FiveseveN barrel will generate the necessary velocity....

Besides, if you need to defeat soft body armor, you can get cases of 5.56, 7.62(x39or51) or even 30/30 WIN just about anywhere, anytime.

5.7? It won't be around long, unless some major Government picks up that PDW concept, or a popular video game showcases it.:D
 
You can get cases of the orginal 5.7 designed to beat body armor. it comes up on auction sites from time to time.

I haven't seen any for years. Current production would be illegal to sell to civilians.

The original round was not bonded, ie; controlled, and some made it to the market before it was removed, but most of it has dried up and what little you see goes for incredible prices. Currently one box on G.B. has a bid of $340. :eek:
 
info

Y'know.....there seems to be limited info available about the 5.7 (not to disparage the .327 at all) or some of us have only limited info.
As to its going away...it has been around since the late 1980's. Yes, it has developed into a "niche" cartridge, whatever that is, but isn't going away anytime soon.

That bullet is probably the least effective bullet for general use. There are other available options that work. Why the little armor piercing bullet gets so much attention remains a puzzle.
Elite Ammunition sells some enhanced loadings - substantially more zip than the factory 195/196/197s. Their "Protector" rounds (a 45 grain bullet at 2000+fps) are, energy wise and penetration wise, in the same league as the 115 grain 9mm round.

You completely miss the point that you are still stuck with a handgun with 22 magnum terminal ballistics. WWB 9mm FMJ has better terminal ballistics than the best 5.7 loads.

No. I don't miss the point. I do agree with the comment about terminal ballistics. Nice to see the comparative gel photos.
I have always thought that having a pistol that fires 20 rounds each equivalent to a rifle fired .22 magnum is not a bad thing.
Controllable, accurate, reliable, reasonably powerful. It may help to understand that my own interest in the 5.7 is not related to SD. I was reacting to the glorified .22 Magnum and the new Keltec pistol idea.

Added PS: Do you know, offhand which .22 magnum was used in that gel test...and which flavor of 5.7X28? There are quite a few of each. Be nice to know.

Prior to the adoption of the term "magnum" by the handgun industry, the previous favored term to project increased power was "special." The .38 special was more powerful than the .38 S&W, or the .38 Long Colt. The .44 special was more powerful than the .44-40.


You mean the .44Russian.. The .44-40 was, and still is, more powerful than the .44special.

Right on though on the rest. "Magnum" is just a larger, and more powerful, version of a existing base cartridge. "Special" is generally a more powerful cartridge of a parent cartridge, but in some cases it is a lessor cartridge of a more powerful parent(.500 S&W Special). And then there is the rare situation where it is "special" due to another feature/function/purpose(.32 Winchester Special).
 
I almost bought 2000 rounds of it a few months ago that I saw on GB, but not owning the gun, I couldnt justify it. I think it went for about 800 or so.
 
"5.7? It won't be around long, unless some major Government picks up that PDW concept, or a popular video game showcases it."

I think our secret service has gone to using the p90 nowadays. No more Uzi.

I can guarantee that wasn't a case of the SS190 rounds. ;) Probably the currently available 195 or 197 ammo. A case goes for $17 to $18 per box typically.
 
My point exactly. The main advantage of .327Mag vs. .38Spl from a SD standpoint is that it offers more kinetic energy and typically an additional round in a snub revolver. It is not milder and easier to shoot.

It's an easier to shoot round than the .357magnum, I have the same gun chambered for both cartridges so can comment from an educated standpoint about the two rounds.

It carries more energy than .38 special and you get one extra round in the same gun, but isn't easier to shoot than .38. However, the .327 does hit targets with more energy than the .38.

The muzzle blast isn't all that explosive like some would have you believe. Heck, if you have ever shot .357magnum for any length of time you are more than ready for the muzzle blast of a .327. It's just not that bad at all. Fun shooter in the sp101 and the Blackhawk.
 
Hands down, I'd go with the .327 Federal Magnum.

It was designed at the outset to be a SD cartridge. That's one reason the velocity and pressures were pushed quite high for the small round. Getting an honest 1300-1400 out of a 3" barrel takes some gee-whiz behind the bullet.

In comparison to other cartridges, the energy produced by the .327 Mag is comparable to that of the .40 S&W. This is more than the .38+P and 9mm+P factory offerings as well.

The bullets in the .327 Mag are on the "light" side for handgun rounds - 85-115 grains -- so they won't necessarily rip through six types of bedroom furniture before exiting the room like a heavier magnum. For those people who want the 6th round in a small wheelgun and/or something a bit less violent than a .357 Mag, the .327 fills that hole.

I'm amused that some people will suggest their "bottom end" is a .38 caliber gun -- .38 special, .380 ACP or 9mm -- and they turn their nose up a the .327 Magnum. The chart above should give them pause.

I have nothing against the 5.7x28 round. But then, I have little to say in support of it. I've fired it and was not terribly impressed. I don't understand the attraction -- as a hunting round, it doesn't seem to do anything significantly better than the .22WMR. I would presume it'd tear up quite a lot of meat too. In a handgun, it makes impressive noise and flash, but I don't know that it'd be that effective as a manstopper. In a Class-III PDW with a 5-round burst mode, it might work out to be a good gun.

As far as availability of guns goes, the .327 is offered from S&W, Charter, Taurus and Ruger in at least 7 different models. The 5.7 is... oh, FN.

S&W Model 632 Pro series from the 2010 SHOT show.
 
Do some reading about the 5.7x28 and the 22mag. They are ballistically similar the 5.7 still has some power on it but the round is not all its cracked up to be.
When both bullets are fired out of pistol barrels, the 5.7x28mm produces nearly double the velocity of the .22 WMR. Kel-tec estimates only 1200 ft/s with a 40 grain bullet, fired from a pistol. EA is pushing bullets of that same weight at 2000 to 2100 ft/s, also fired from a pistol. EA's numbers have also been independently chronographed by various publications.

The Five-seveN can have the same 30-round magazine capacity using CMMG's extension, which only sticks out about 1.5 inches.



The Five-Seven is over-priced, over-hyped, and the only civilian ammo available is not at its full potential (and using bullets that are insanely stupid for a home defense choice).
Civilians have access to 5.7x28mm ammunition that is "full potential", and it performs substantially better than FN's SS190.



I dont think the 5.7 will survive..I would stick with the 327.
The 5.7x28mm has already survived for 20 years. There is no reason to believe it won't continue to do so.



Um, it is anemic vs other rounds. balistic testing and real world results prove that.
"Ballistic testing and real world results" has not proven anything of the sort.



He could have done the same with a 22 rimfire pistol.
This is speculation and I'm sure you can't substantiate it with an example.



13 were killed, but 30 were wounded as well so it's not like it was some death ray.
Handheld weapons of any caliber are not "death rays" so this should not be surprising. According to news reports most of the wounded were struck in extremities, including the female police officer that was shot in the leg.

According to her blog the doctors feared she would die or, at the least, lose her leg. The bottom of her femur bone was "blown into hundreds of bone fragments" according to her post on her blog. She underwent a number of surgeries resulting in an artificial knee replacement, and she is no longer able to do street patrol work.

News reports are filled with similar stories from the shooting. One of the deceased even tried to rush the shooter and approached to within inches of him before being shot and killed. Keep in mind, the shooter used FN's watered down factory ammunition. EA's 5.7x28mm ammunition is pushing heavier bullets at significantly higher velocities.



Virginia Tech had 32 dead and only 17 wounded using a 9mm and a 22 rimfire.
25 were wounded in the Virginia Tech massacre, not 17. The shooter carried a .22 LR but he fired the 9mm Glock. He also fired nearly twice as many rounds as the Fort Hood shooter (170+ vs ~100), and almost all of his victims (including the two dormitory victims precluding the actual massacre) were shot in the head.



You completely miss the point that you are still stuck with a handgun with 22 magnum terminal ballistics.
This statement is useless because you are talking about a bullet that is similar to .22 WMR from a rifle, not .22 WMR from a pistol. Some .22 WMR loadings from a rifle actually give peformance similar to 9mm loadings from a pistol.

In addition, you are most likely not even aware of a single shooting with a .22 WMR fired from a rifle, let alone any meaningful number of shootings.



In comparison to other cartridges, the energy produced by the .327 Mag is comparable to that of the .40 S&W. This is more than the .38+P and 9mm+P factory offerings as well.
Energy is irrelevant in a discussion about pistol performance. Energy does not wound.
 
Civilians have access to 5.7x28mm ammunition that is "full potential", and it performs substantially better than FN's SS190.

Like what?
- A 27 grain Jacketed Hollow Point that is hard-pressed to reach 1,600 fps? What exactly do Five-Seven shooters expect from a 27 grain varmint bullet in a self defense situation?
- A 40 grain V-Max? Again... do you really think the V-Max is a good choice here? It is designed for instantaneous, explosive expansion. Horrible, horrible wounds might result, but I doubt they would be debilitating to an attacker, unless a head shot was made (and then you'll have some additional explanations you'll have to give to LEOs).


The Five-Seven pistol slings bullets weighing one third that of the .327 Magnum, but is pushing only marginally more velocity than the .327 - with the wrong bullet construction!


If you want to repel the hoards of zombies, use the mega-capacity of the Five-Seven.

If you're still on this planet, the .327 is the logical choice.
