Make no mistake the 7,62 NATO has it's place, but I think it is senseless to arm every foot soldier with this heavy and recoil intensive weapon. Sure, he can reach out and touch someone beyond 500 meters, but that is what the GPMG and DM is for, right?
The more I look at it, the more I begin to see where the Army is going with this. They want a round that has enough umphf to replace the 7.62 NaTO as a GPMG round, yet light enough recoil and size to replace the 5.56 as an AR round. May just be the "Wonder Cartridge" we needed in VN!
What of the 6.5 Grendel. I've read that it out performs the 6.8 quite a bit.

Amen. It's got it's place. I just think it's not that great for the regular line soldier.

Here is a great website.... http://www.constantforce.com/index4.htm

I've never fired any mounted MG's but I did fire PKM from bipod quite alot actually and I can tell its good for all the way to 500 meters even 700 if there happens to be clear weather and no wind, firing short bursts no more than three rounds which is what I did all the time, we didin't carried that much ammo

See? Now that's where the 7.62mm finds its home.

the 5.56mm has its history of going in one end and coming out a total different other. And believe me it has the power to knock a man down. Seriously if any man has been hit and is still moving up you got to think to your self, is this guy psycho or human?

Its been doing well in UK the Rifle on the other hand is a different story lol

either way it kept me safe in Gulf lol

If someone says 5.56mm round is a poor man stopper then that person doesn't know what he/she is talking about. the nato bullet is small and flies about 1000 meters per second, there's this thing called hydostatic shock that occurs when that 5.56mm bullet hits soft tissue like human.

"the 5.56mm has its history of going in one end and coming out a total different other. And believe me it has the power to knock a man down. Seriously if any man has been hit and is still moving up you got to think to your self, is this guy psycho or human?"

Im not sure about that entry- outcome wound, isn't the russian 5.45mm bullet like that?

The 5.56 was designed to tumble once it hit target, problem is, with the lshorter barrels on the M4, the range at which this ballistic effect happens, is much shorter...something like 150 meters! This means that if smeone shoots at a human with an M4, and the target is more than 150 meters away, the bullet will just glide straight through the target, making a small entry and exit wound - with no shock or knock down power....unless it hits bone. I'm willin to bet that a 5.56 in the head at 500 meters is just as dangerous as a 7.62, but a head is a small target, right?
The 5.56 is a good round...and since it is produced in such massive amounts, very cheap. As long as you have a 20" barelled M16, the 5.56 should be very effective up to 300 meters IMO. I still think they should dig the prototype 5.56 minigun out and mount them on HMMV's as anti-personnel weapons...

Hydrostatic shock is a myth. It simply doesn't happen.

Tumbling is the key. When that bullet hits the target and tubles, the result is a MASSIVE exit wound. This means that the superior penetration of the 5.56mm will get through body armor and transfer its energy into the enemy much more effectively than people normally give it credit for.

HMMMM THINKING ABOUT IT MORE AND MORE....
Seems many people love the 5.56 for it's compact size and low recoil, other hate it for lack of stopping power and lack of range....
....
So why not compromise? Personally, I would equip an army with either a combo of 5.56 AR's and 7.62 GPMG OR AR's and GPMG's chambered in 6x45mm - basically a 5.56 case with a 6mm bullet. The higher sectional density gives it additoinal range, knock down power and penetration....
Make sense? Of crouse the HMMV mounted .50 will always be around when STHTF.
