And I thought this one was probably dead.....
Defence Research and Development Organisation (DRDO) designed 5.56x30 mm Protective Carbine has successfully undergone the final phase of User trials on 7th December 2020 meeting all the GSQR parameters. This has paved the way for induction into the services.
This was the last leg of trials in a series of User trials which have been carried out in extreme temperature conditions in summer and high altitudes in winter. JVPC has successfully met the stringent performance criteria of reliability and accuracy in addition to quality trials conducted by DGQA.
JVPC is a Gas Operated Semi Bull-pup automatic weapon having more than 700 rpm rate of fire. The effective range of the carbine is more than 100 m and weighs about 3.0 kg with key features like high reliability, low recoil, retractable Butt, ergonomic design, single hand firing capability, and multiple Picatinny rails etc. These features make it a very potent weapon for Counter Insurgency /Counter Terrorism operations by security agencies.
The carbine has been designed as per Indian Army’s GSQR, by Armament Research and Development Establishment (ARDE), a Pune based laboratory of DRDO. The Weapon is manufactured at Small Arms Factory, Kanpur while the Ammunition is manufactured at ammunition Factory, Kirkee Pune.
The weapon has already passed the MHA trials and procurement action is initiated by the CAPFs and various State Police organisations.
Raksha Mantri Shri Rajnath Singh had unveiled the 5.56 x 30 mm JVPC during DefExpo- 2020 at Lucknow.

There's a part of me that wants it to succeed. Whether or not it will is the question. A successful Indian small arms project would make their chances of producing copies of other carbines for military purposes more likely to be successful.

Interesting that they are looking at new caliber when 5.7x28 is on the market .
A good PDW is always welcome but honestly, Indian defense projects have a tendency to go sideways really fast , Like in Bollywood the seem to go for a dance sequence instead fo action LOL

I love 5.7x28, but the 5.56x30 is a whole level above ballistically.
Seems based on the Colt MARS cartridge; 55gr @ 2620fps from a 10" barrel.

The cartridge may be similar in dimensions to the Colt Mars, but the ballistics are far weaker: 40 grain bullet at 2,300 fps from a 13" barrel, as far as I can make out.

"The cartridge may be similar in dimensions to the Colt Mars, but the ballistics are far weaker: 40 grain bullet at 2,300 fps from a 13" barrel, as far as I can make out."
Wow, thats terrible.
.22 TCM (5.56x26) launches a 40gr 2000fps from a 5" barrel. It's doing 2700-2800fps from a 22"; I have little doubt it would meet or exceed 2300fps from a 13".
Full power (ie not FN SS197) 5.7x28 40gr is 1900-1950fps from a 4.75" barrel, and 2350-2450fps from a 16" PS90.

I wonder how high the pressure of the 5.56x30 MARS was, given that it apparently was high enough to cause problems.
26-Dec
The MARS had problems with bulging or ruptured cases. Energy was similar to 556 in 10' barrels.
556insas performance is about halfway between the MARS, and smaller 5.7x28.

I am aware. I am assuming that can be fixed with stronger cases. Or otherwise go to .221 Fireball.

As far as I can see fireball is identical to MARS other than an extra 3mm OAL.
KAC also used the fireball for their 6MM PDW
