U.S. Army Says 5.56mm Is Adequate
« Reply #30 on: June 09, 2006, 09:12:58 PM »
Youre right, and in my posts, other than when noted I reffer to the 7.62x39 that is fired by the AK and SKS, amongst others.  I think this is a better comparison than the .223 vs .308.  The .308 just wasn't designed as an assault rifle round.  Still, I am no expert.

I don't think anyone would be foolish enough to equip soldiers with ammunition intended to wound rather than kill.  Anyone would have to be foolish to think that they could create such a round.  Now, I'm not arguing that we give our troops frangable ammunition,  but it seems to me that the penetration power of a .308 could prove to be a liability in some tactical situations.  No tool is perfect.  

.308 is better for longer range, penetration or where you really need the power to drop someone.

7.62x39 has been a good round for carbines and assault rifles for a long time, but it's old and better things have been developed more recently.  I suppose it could be reworked with better powder or something, but it does what it's supposed to do.  If flies cheeply and relatively reliably across the third world.

.223 is all around a pretty decent round, but accells at nothing specifically.  The army wanted a jack of all trades and got it.  Could possibly be better, but it could be a laser rifle too.  

I think it's important here to think about the army's invested interest in the .223 round with regard to the article at the top of this thread.  If the army declared it infereor, it would have to replace all that ammo and all those weapons.  The logistics is staggering.  When they can't even get our troops the stuff they need, like batteries and enough water, the last thing we need to do is yank their rifles out of their hands.  Something about a cluster comes to mind....Still, this could be a big reason for the Army liking it so much.

....they also missed a hell of a lot more.

Did they take into account snipers?

BTW the M16 started out as the Armalite AR15 impressing an Air Force General (yeah, a REAL authority on weapons) by blowing up some watermelons.
Was supposed to be a survival rifle. Then McNamara got into the act and wanted all services to use the same weapon.
Original barrel twist was 1 in 14" but they found the 55grain bullet tumbling in the dense winter air. Tightened it to 1 in 12" to stabilize it but resulted in inconsistent tumbling after striking the "target".

The 5.56 x 45mm is a compromise at best. I don't like it all that much.

My fave all time is the Galil AR308. Very accurate, comfortable, and balanced. Above all, RELIABLE and simple. The spent gasses never contaminate the bolt assembly.

68Hawk,
Don't confuse my liking the 308 as somehow saying it is okay for an "assault" rifle for it is not. It just does better for consistant damage for a far longer range than the 5.56mm.

Its the same mechanisms and cartridge.  The only difference is the length of the barrel 14.5 inches vs 20 inches which reduces the muzzle velocity slightly.

Sort of.  It started out as the AR-10, lost the competition to the M14, was recalibered in 5.56mm for survival rifle, then turned into the M-16

I think the 7.62x51 is a fine round for an assault rifle.  Not an expert either but the cartridge excels at everything.  It would be the length of the M14 that makes it a less than perfect assault weapon.  In the Sage stock, it is a great assault weapon with the power to knock down with a less than perfectly placed round, and the ability to shoot through many barriers to take an enemy out.  Additionally I believe the 168gr bullet to be less disturbed by light brush than a 5.56.

It is not a great round for hand held rapid fire, but most hand held rapid fire is notoriously inaccurate with any weapon in the excitement of combat.

If we really wanted one shot kills more often, we could switch to frangible bullets.  

Bullet placement is key if your cartridge isn't a great stopper.

"that the smaller round was chosen partially for its ability to cause casuallties and not just dead people"

I have never heard of this being the reason, perhaps the "556 fan club" has in retrospect, trotted that out... when the Germans went with the Mp44 Assault Rifle in 1944 (using a cut down 7.92 rnd) it had nothing to do with that, nor did the Soviets or NATO move to intermediate rounds to do that. Its simply about firepower and usage issues, for the kind of fighting they were expecting to have to do. Most infantry casualties are caused by artillery and mortars anyways, and that has been the case since at least WW1.

Myself im not "anti 556" I just know some of the things stated like "weight savings" are just subderfuge. Both 308 and 556 have their good points and applications.

I beg to differ. that's precisely what it was designed for.. the first 'assault rifle' was the Russian SVT-40.. firing the massive 7.62x54 round. Hard to find one with a barrell that's not shot our these days. ;) When the Germans began capturing them in 1940, they sent 'em back for evaluation. The troops, meanwhile; kept a fair number themselves and they employed it as a sniper weapon... a testament to it's accuracy and the ability to shoot multiple times (10 round mag) without any body movement as required with a bolt action.. sniper position isn't given away.

meanwhile, back at the arms factory, the germans used the gas operating system from the SVT in developing the MP43. Unfortunately, the Russians were unable to capitalize on their SVT-40's.. the troops just failed miserably at keeping the complicated SVT's operating. Peasants. ;) In the intrest of developing an automatic assault rifle for urban conflct they changed horses and introduced the PPSh.. the Gemans got the Mp43's in service first. Both the the german and the new russian weapon used a smaller cartridge.. and this is where the development  of the modern 'assault carbine' split of from the companion development of the Assault RIFLE.

While all this was going on John Garand was building and refining the most competent battle rifle in history.. an outsanding companion to the worlds best SAW.. the Browning Automatic Rifle. It's no coincidence they were both firing 30-06 slugs; and they dominated on the battlefield.. fitting Savages's description of VASTLY SUPERIOR & EXCEPTIONALLY EFFECTIVE perfectly.

Postwar, the East went with refinements of the SMG/PPSh path, developing first the SKS, and shortly thereafter, the AK47. While the Allies and the Axis slugged it out in Europe, the weapons guru's at FN hauled butt to england with thier prototype Assault RIFLE.. and post war they offered it to NATO and the US.. we damn near bought it.. but John Garand got a look at it and the folks at Springfield trotted out a competing rifle... what became the M-14.. arguably the best Battle/Assault Rifle ever issued to an American Soldier. Meanwile, FN continued their development.. and the rest of the free world came to know it as the FAL. Also, arguably, the finest assault RIFLE ever issued in the free world. Both the M-14 and the FAL use the 7.62x51 NATO round... aka, the .308

For 25 years, the three players in the Assault Rifle world were the AK47, the M-14 and The FN/FAL... and there is no doubt in anybodys mind as to which weapons were superior on the battlefield.. The Russians developed the legendary Druganov (7.62x54) to counter the range and punch advantage posed by the M-14 and FAL. Thanks to AF General Curtiss LeMay, politics and contracts the M-14 was replaced by the M-16. NATO was brought to heel eventually.. with most NATO forces downgrading to 5.56 weapons soon after.

It would seem the biggest gripe of the large caliber Assault (full auto) Rifle was control of the weapon in auto mode. At this time, marksmanship skills were a large part of infantry training.. and Full Auto was reserved for appropriate circumstances while accuracy and controlled AIMED fire was empathsized for fire and manuver. This quickly gave way to 'indirect & mass fire' doctrine with the advent of the M-16... using the weapons percieved strengths. percieved, because the damn thing would jam if you looked at it funny... No kidding. Some doofus REMF general decided to use ball powder, which caulked the M-16 real quick. In my day the M-16 was roundly despised, the M-14 was a prized possession, worth any number of cigarettes or bottles of Jack. ;)

*sigh*

Time and again.. as our troops have re-defined the battlefield with new adversarys, the need for the M-14/FAL type Assault RIFLE has reared it's head.. and they find their way to the front as the most trusted, competent and as Savage said " VASTLY SUPERIOR & EXCEPTIONALLY EFFECTIVE" weapons for our troops when compared to the enemy's AK's and their own lil mousegun carbines.

In closing.. yes there will always be a place in the modern force for an assault carbine... it's what we've been using for the last 35 years and the russians have been using for the last 56 years. There is also a pressing need for an Assualt RIFLE.. which is why they keep revisting the 'large caliber' round concept.

I rest my case.

;)

The AR-10 wasn't helped when one of them with a fancy titanium barrel blew-up during trials the US Army conducted with the rifle.

The initial trials between the AR-15 and M-14 were rigged in favour of the M-14. The AR-15 won out in the end but the US Army didn't want to give up their Springfield baby to an outside competitors rifle. At least that's what I've read.

But does it qualify as an assualt rifle? Does it have the selective fire feature? I was of the belief that Hitler himself coined the term 'assault rifle', or 'sturmgewehr' for the MP44--which featured the shortened 7.92 x 31 round, as opposed to the full size Soviet 7.62 x 54.

The selective fire, coupled with the high capacity magazine and the smaller round, I'd always thought, were the prerequisites for a proper assault rifle. Everything else is just a self-loading rifle, including the M1.

Right?

Yup. The SVT was an auto-loading rifle.. like the Garand. Unlike the Garand, the Russians took the development further, and faster... and released the AVT (full auto version) by 1943. There is a lineage connection between the SVT/AVT-40 and the legendary german SMG.

Now come on, the liberal gun grabbers have identified anything that holds more than 10 rounds as an assault weapon.  Don't forget the abominable items like flash hider (oh so dangerous), the bayonet lug (an integral requirement for drive-by bayonetting) and the large capacity magazine (scarey looking thing).  :D

The battlepacks have "bandoliers" in them?  I have a couple thousand rounds of Aussie in bandoliers.

Good plan on the stock up, if not just for future events planning, it is a good investment plus the milsurp will be continuing to dry up I fear.  Cheap shooting is the best shooting.

I might start buying a few cans, but the wife gonna crap when more ammo starts arriving.   She is never to happy when a big heavy box or two arrives at the door.  :)

I do appreciate ammo in battlepacks for the hermetic storage factor.
