What is best calibre for an Assault Rifle?

[Akim]

experienced Ukrainian sniper Rifle

Caliber
5,45*39. 7,62*39 mm
Amount of rifling - 6
Long barrel a 520 mm
A step of rifling is a 260 mm
Effective distance of shot is 800 meters.
Practical distance is 600 meters.
A capacity of magazine is 10,20,30 cartridges
As see she outwardly does not differ from Kalash, but carries in itself other descriptions.

Akim
Since it does not sell anywhere those are exceptional..

As you had rightly said in one of your thread, such a large Army as IA, it needs universal acceptance, applicability and availability.

 

[W.G.Ewald]

India uses all.

For details, I'll let Ray Sir, Kunal, Mr. Ewald, Akim, et al., answer that.

My preference is 7.62x51 and M14, just because it was standard issue during my service time. I understand that 5.56 is smaller and soldier can carry more of it. If I had to shoot at hostile people today -- very unlikely -- I would ask for a Bulgarian AK-47 (7.62x39).

 

[BangersAndMash]

Best assault rifle....that would be none....

@ kunal, bhadra & Akim can u tell is im rite or wrong bcoz i think in high alti and mountain warfare u need long range but light weight as u said barrel increase range so bullup gun with 6.5 or 6.8 may b good option bcoz 7.62 creates lot noise in case 7.62 bull it will bang ur ear drum wat u think can we do R & D in this zone.

You me did not understand. In in mountainous terrain, at less air density, more heavy and large bullet tests the same resistance as well as bullet of small caliber on a plain. And as an aiming firing is conducted on distance 400-600 meters, then advantages of small-bore bullet are lost. Besides in mountains permanent side wind and to the bullet 5,45-5,8 with him heavier coping.

I am glad people are talking about weight here. There is nothing more important about the logistics and ergonomic effects of weight on a soldier. Considering I can carry more than twice as much 5.56 than 7.62 I will take the smaller round any day. That calibre is covered by snipers and SAW which is where it should stay.

It his only advantage is weight. But in jungles or city, better имет a 1 cartridge of 6,8-7,6мм, what 10 cartridges 5,45-5,56. Do you know how many injured was the ricochet of people in Bender (Transnistria)?

Bullpup is the best solution in my view..

With 6.8 / 6.5 will carry more ammo also 6.8 / 6.5 recoil is not harder as 7.62x39..

----------------------------

5.56mm makes more sound than 7.62x39mm or even 7.62x51mm..

5.56mm sound is irritating not sweet as 7.62X51mm..

 

[Sunder singh]

so this we all agree to a gun ie Bullup with 6.5 mm for asult rifle in indian army.

[Akim]

Not renounce a cartridge 7,62*39. you will look at these two carbines of АК- 47 and SKS. At SKS exactness at firing on 400 meters without an optics as at SVD.

 

[rock127]

From calibers 5,45, 5,56, 5,8 the best are a 6,5 mm! What caliber at the assault rifles of India - 7,62*39? Here him and use. On the Chinese cartridge, nothing will say is I him in hands did not hold. On «soviet» and NATO littleimpulsive cartridge too much censures. They are good only on flat locality. Substantial advantages between them it is not, unless 5,45 - a mm heavier than wound to inflict. Both cartridges often ricochet and in city and in forrest. In mountains, where pressure of air below, they lose the internalss also. India with anybody does not stand in military alliances, what to use identical standards. Pass at once to the caliber 6,5*39 мм. And М-4 and Ак-74, easily Remade under this caliber.

5.5 is light and 7.62 is kinda heavy.

I saw a program on Discovery about weapons and they demonstrated a new gun(cant remember it's name) with 6.5 mm bullet which has the same effect as 7.62 AK.

My bad going for both, I assume after heavy trails on Indian terrain one will be selected..

That's right, I watch it a lot... I was wondering about the name of the gun actually, perhaps it was of M series.It was tested along with AK.

 

[Kunal Biswas]

Multi-Caliber



At close ranges 6.5 preform better as seen in tests, But in longer range 6.8 preform better..

 

[Sunder singh]

thsnk kunal for information of Rfi hope it will b a tough compitition like Mmrca and some thing best come out of it i personally like masada bushmaster with changable caliber but if bullup then Kel-Tec RFB which uses SLR 7.62 magine hope they can learn from masada to interchange caliber.
