5.7 Good Enough for You?

[joshua]

Manedwolf, this thread is to put the 5.7 under the spotlight and not to criticize the AR platform. josh

Shot your .223 pistol over a chrono? I'm guessing "No."

I'm at work, so I'll have to edit with exact numbers when I get home, but IIRC 55 gr. Federal (L.C.) was about 2,600 FPS and my 40 gr. V-max handloads were over 3,100.

Say what? From a 7.5" bbl? Hrmmmmm. :skepticalsmiley:

But then, I have a 5.56 AK that doesn't have the delicate constitution of the AR platform

Oh, now that's a low blow, MW.

9.2"

Interesting.... 9.2" .... and that claims, with 55 gr M193, it gets 2,600 fps with .223 and 800 m/s with 5.56 - that's 2,625 fps. Just what you said.

3,100 with 40 grain v-max is sure impressive.

What does the P90's 28 grainer get from a 16", and from a 10.2" bbl?

Personaly for my preferences that is on the small side. Punching small high speen holes isnt my idea of a good man stopper. Since we are in the rifle section I wont go into my preference for shotgun for hd or a good handgun like a .44 mag. A good .308 semi AR or even the new ruger ranch carbine in 6.8spc. Or how about a remington 750 carbine in .35 whelen with a ten round mag. That'll do the trick.

OK, now that I'm home, the Chronograph results for my PLR are:

Federal American Eagle 55 gr. ball: 2581 FPS avg for 40 rounds

40 grain Blitzking/30.0 grs. H335: 3137 FPS avg. for 20 rounds

40 grain V-max/24.0 grs. IMR 4198: 2976 FPS avg. for 20 rounds

These same loads ran out of my 24" Howa M-1500 at 3267, 3841 and 3630 FPS, respectively.

From my 16" Armalite M-15 carbine the ball ammo averaged 2972 FPS and the 40 grain Blitkings got 3,736 FPS.

As an aside, 30 grains H335 is a bit hot and do not recommend that load. Anyone who chooses to try it does so at their own risk.

I thought the original question wasn't whether the AR or FN was better, but rather if the PS-90 was *adequate* for home defense. Off the cuff after firing a couple mags through one, I'd say, unequivocally, probably. Easy to control, etc. etc.

Also remember the original P90 was designed around the PDW concept, aka
"fits-in-the-cockpit-with-me-so-if-I-get-shot-down-over-turkijurkistan-I-won't-be-stuck-with-just-my-pistol"

It's an upgrade over a pistol...on that we can ALL agree, hopefully.

imho

my 5-7 punches holes in the yard critters that i point it at. that's all i ask of it. it also rests on my nightstand for after dark problems. how many after dark problems come equipped with sba anyway?

I absolutely wouldn't trust it. This thread has been done to death. To each his own...

 

[BunkerBuster]

ETA: IT is really upto the shooter. What is suitable.
