"We are replacing the conventional carbines with lightweight single hand firing capability MSMC, which has new ammunition. All technical trials are successfully over.
The MSMC, a 3 kg gun with optical sighting facility and laser pointer, has a 200m range and can be fired accurately using one hand only.The new MSMC is a 5.56 mm calibre gun with new propellants inside the ammunition..
Today, this weapon has accuracy that is within the Army's needs and it can penetrate through body armour of the enemy soldier," he said.

India's new Modern Submachine Carbine (MSMC) and 5.56x30mm Ammunition
The firearm chambers a round developed in India called the 5.56x30mm. This round is sometimes referred to as the "5.56x30mm INSAS" after the first gun to chambered the round, the INSAS Carbine.
Those of you who follow the industry closely may recall tha
t Colt developed a round named the 5.56x30mm MARS during the 90"²s as part of their now defunct Mini Assault Rifle project. I imagine the INSAS cartridge is very similar. The Colt patent describes the MARS cartridge:
The MARS cartridge is designed as part of the weapon system and exploits the high energy densities of modern ball powders. It for the first time uses magnum pistol type powders burned at rifle pressures to achieve high rifle velocities in a short rifle barrel. It uses a fast ball powder to achieve 2600 ft/sec with a 55 gr full metal jacket projectile in only an 11 inch barrel.
The MARS cartridge/rifle was able to achieve similar ballistics as a ultra-short barreled 5.56x45mm NATO rifle (I use the term rifle loosely, sub-carbine is more correct), but with less muzzle flash, noise and weight.
The Indians went with the 5.56x30mm over the 5.56x45mm for these exact same reasons as Colt.
Out of a 11"³ barrel, the MARS Rifle was able to push a 55 grain bullet at 2600 fps, generating 825 ft/lbs of muzzle energy. For comparison, according to Wikipedia, the original Colt Commando (11"³ barreled sub-carbine) could push a bullet (presumably a 55 grain M193 Ball) at 2750 fps.
