Trichy Assault Rifle

[Sunder singh]

Question. What parameters did you define 7,63*39 - worst?

1. i dont think 7.62 has more range then 5.56 but it has poor accuracy in AKs.
2. im not a fan of 7.62 bcoz contineouse firong makes for bit tired.
3. huge explosion near ur ears if some firing near u makes u almost deaf.
4. how many magines u can carry with a pair grinades plus pitthu and pouch etc.

why i hate about 5.56
1. no one want its enemy to stand and again fight after geting a hit from u or ur buddy.
2. bullet proof r bcoming lighter and tougher with kavler wat if its doesnt penitrate.
3. prone to climatic condition its rain allmost every day in north east india and snown above tawang and anni.

Why then in the USA actively discuss passing to the cartridge of caliber 6,5-6,8 mm. And he on parameters nearer to М- 43 (7,62mm)?. There is the system: a weapon - a cartridge. you discuss a weapon only. Certainly АК, which was invented in 1946 not to compare to G - 11. But cartridge better what 223 Remington.

For an infantryman a substantial difference is not present. And that and that cartridges are good. But it is necessary to take into account logistic yet and. Translation of such large army, as Indian on a new caliber is enough nevertheless an expensive thing. Cheaper yet a bunch of Rafal to purchase. It is simpler to work out a new assault rifle under the caliber of army cartridge. You have advantage - there is a cartridge 7,62*39 мм. In the USA of "intermediate cartridge" of such power in an army not.

re: What is best calibre for an Assault Rifle?

6.8 is better than any other, 6.5 is very good in close ranges as per gelatin tests..

In Indian terrain presently 7.62x39mm have better kill preform ace than 5.56mm, though 5.56mm SS109 can shred Level 3 protection at ranges over 150m..


6.8mm is under Multi-cal AR RFI..


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

There is a new AR which use M43 rounds and have range over 400m..

re: What is best calibre for an Assault Rifle?

7.62x39 - Kalashnikov
7.62x51 - (NATO standard) SMLE, SLR
7.62x54R - (Rimmed) PK, Dragunov

which one do india use and why any strategy behind

1. In CT ops 7.62m43 have more stopping power and effective against tangos, the recoil of M43 is sustainable..

2. Used in MMG and LMG ( Bren ) one shot one kill round but in AR its not good coz of Recoil so used only in LMG & MMG and now days Sniper Rifles..

3. Used in SVD and these are imported and used in PKM ( Captured ), PKM used in CT as IA dont have a GPMG...

plzz may b they can also tell about countering chinese 5.8 caliber

5.8 preform ace is not at same level as newer 6.5 & 6.8, Its range is little more than M43 but have good stopping power than 5.56mm

re: What is best calibre for an Assault Rifle?

2. insas has low kill rate even if not been armored person.

Never underestimate a round, only because it's .22 diameter bullet....

re: What is best calibre for an Assault Rifle?

I am a not theorist, I am a practical worker. you all see in a table, that 5.45 inflicts more frightful wounds what 7,62. But it in a theory. In Transdniestria, or Chechnya specially passed with АК- 74 on АКМ.
And modern specimens of AR under 7,62, have 6 rifling, other step of rifling, burning sleeve, new gas mechanism, systems absorbing return et cetera. And all these nullify level advantages of small-bore cartridge and 7,62*39 put on a level 6,8*45 mm.

I seriously doubt so, because..

Both Rounds fired for 16inch barrel : 415MM

7.62X39mm 123.5 gr Fmj
Velocity is 731.5 m/s
Energy: 2,073.6 J

For a heavy bullet at lesser velocity its Range is 200m straight without elevating..

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

6.8mm SPC 115 gr FMJ
Velocity is 785 m/s..
Energy: 2,297 J

For lighter bullet with more velocity its Range is 400m straight without elevating..

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

But it can be possible if longer barrel Rifle is used to fire 7.62X39mm the range can be increased..

This Indian Rifle which is heavy influenced by FAL & AKM with a barrel length of 464mm archived firing 7.62X39 at ranges 400meters..

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

Regarding Wound i assume 7.62mm also trembled but unlikely 5.45mm/5.56mm preform much better in this regard..

But

7.62 X 39 a slower and Heavy bullet have better Hydrostatic shock which works better in stopping Tangos, regardless where it hits..

Hydrostatic shock or hydraulic shock describes the observation that a penetrating projectile can produce remote wounding and incapacitating effects in living targets through a hydraulic effect in their liquid-filled tissues, in addition to local effects in tissue caused by direct impact.[1][2] There is scientific evidence that hydrostatic shock can produce remote neural damage and produce incapacitation more quickly than blood loss effects.

re: What is best calibre for an Assault Rifle?

You again compare descriptions for firing from a regular weapon. But ordinary cartridges are long-livers . Cartridge 7,62*54 (1891), did not especially change from 1906, and used and now in the modern Russian machine guns "Pecheneg". Cartridge 7,62*39 in the modern Ukrainian sniper rifles able to strike exactly target on distance 800-900 meters. At the old machine-gun of RPD quite another ballistic what at RPK - and they use identical ammunition.
P.S. RPD-best

Indeed but i believe it have more to do with Rifle barrel length..

New Cartridge increase velocity ?

Even if length was to more 7.62 X 39 is not a fit sniper round for 800 - 900 m.

That way 5.56 LMG on bi pod with a single shot mode is better sniper at 500 -600m

Yes, you are right. Increased long barrel, ammunition is changed, and that I wrote before. It is a single mechanism Now airplanes and rockets of calculated on computers, but not that that rifles!
Distance 800m.
SVD have MOA -1,04
M-24 have -1,18
experienced Ukrainian Rifle 7,62*39 -1,19 MOA

re: What is best calibre for an Assault Rifle?

@ 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.

re: What is best calibre for an Assault Rifle?

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..

 

[Akim]

re: What is best calibre for an Assault Rifle?

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.

re: What is best calibre for an Assault Rifle?

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.

Trichy assault rifle

Kunal please explain how this gun can hit a target beyond 400mts as the effective range of M43 when fired from ARs are below 250mts.400+ range could be achieved only it is fired from LMGs like Rpk or tabuk sniper which have long barells.Here in case of Indian weapon the barell is not that much lengthy to shoot over a distance of 400mts.I think the range and over effectiveness is much hyped as usually happens in every OFB products.
