Can tell me whatever you want... isn't going to change my opinion on it.
Fair enough, Not trying to trying to convert you carry one of these.. hell IM not even carrying one of these that does not mean they don't have advantages.
You don't seem to wanna give a inch though.
If it was such a great idea, wouldn't you see this combination in L/E or military hands? The shortest you tend to see is 10" (under 10" is usually builds that people do for poops and giggles). 5.56mm is a very anemic cartridge, and there is no argument with that. It is a light, high velocity round... just how it was designed (replaced the .308, because of weight).
I've seen videos of swat raids where they're clearly using SBR's of what exact size I can't tell on video.. next you'll be telling me it's like a 22lr with such a short barrel.
Kind of, sort of...
FMJ, like the 62 grain M855 that you brought up, will not reliably fragment under that threshold. Since the 5.56mm was designed to do this, you decrease wound capability dramatically under that velocity.
Look I just picked it out of the list because it had the highest energy on the list.. just like when looking at the 9,40,45 I simply picked the highest one on the list off the wiki.. Pick a different round then.. he shows the bullets after digging them out of the gel, clearly the ones designed to expand did just that.
Hornady 55gr vmax
Penetration (3layers over gel): 16in
Expansion: 0.466 W/fragmentation
Ok back to the m855..
Look at the guys chrono for a 16inch (a full 1.5inch longer then a m4)
He got 2855fps, Ok so 2855 in the balletic calc says at 220yards the round will be going 2326fps.. wow that's pretty close to the 7.5in at 2329 @ muzzle.
Mind you im not trying to claim the 7.5in makes a good replacement rifle where you can shoot ANOTHER 200 yards, im talking about say 20 additional yards close range..
BTW it's 2510fps at 140 yards.. again out of 16inch barrel (Your most common ar15 build).. so I guess you better stick to shots within 100 yards to be safe.
Not talking about accuracy, but if you take the terminal ballistics between a 20" and 7.5" AR... there is going to be a night and day difference in performance with M855. Penetration wise, you are getting to the low end of the spectrum with that slow of a 5.56mm. Don't believe me? Put some rounds into gel or some human-like media... and see what you get.
The page I linked to previously the guy did gel tests.. but whatever.
While I wouldn't want to be shot with a BB gun, if someone is determined to do you harm, I really wouldn't want to trust that performance. Typical handguns might not be anything compared to a rifle, but a 5.56mm pistol isn't giving you rifle performance. Rifles give you rifle performance.
Never said it was going to give you rifle performance.. By all means quote me where I said that or even implied.
It's pretty apparent you're giving up 5-700fps with a 7.5in barrel that wasn't the point, The point was it's still more potent then most handguns.
While you can plug in whatever numbers you want in a ballistic calculator, energy that doesn't transfer into the target isn't a helpful use of that energy. That is what you are getting with a 5.56mm under 2,500 FPS.
Right Understood.. beyond 150 yards m855 is junk out of a 16, message received.
The benefits are far and few between... none of which will be beneficial to a civilian, who is conceal carrying for their own protection. The FiveSeven would probably be a better choice for someone with a use for any of those benefits.
Right cause the 5.7 is such a monster!
It was primarily designed to defeat body armor.
Now things might have changed but I know when the 5.7 hit the market you could not find AP ammo in that caliber.. so ya.. REAL monster.
Let me decide what's beneficial for me.. and I'll let you decide what's right for you.. M'kay?
But to get away from that, you are concealing a cumbersome firearm (magazine well does it to the gun), one that has more bark than bite (going to be yelling at the 911 operator after a shooting because of being deaf), and coming up with a creative way to conceal it. At that point, why? A PDW... really, it would be better suited with a stock if you had the need for a PDW.
PDW is just a descriptive term.. bigger then a handgun smaller then a carbine.. don't read to much into it.
I personally think it will conceal reasonably well under a medium or heavy coat with a single point, I previously said I would give it a shot come winter till then I'd look a bit out of place trying to conceal it under a shirt and people might get suspicious of a heavy coat in summer time.. don't you think?
This was suppose to be a fun thread, Sorry it's turned into sucha bitching match.
Loosen up, I don't care what you carry man, It's not like im getting paid here.
You seem to think Im trying to convert people to this mode of carry when really Im just trying to have some fun.
IM not even carrying one of these.. I just thought it would be fun to think of ways to do it.
