MINSAS

The 5.56×30mm MINSAS is an ammunition manufactured by the Ordnance Factories Board for close quarter battle use. The round is somewhat a derivative of the experimental Colt MARS, using a bottlenecked case 30mm long, loaded with a light pointed bullet with a steel penetrator core. The bullet weighs 2.6 g and muzzle velocity from 300mm (11.8 inches) barrel of the Modern Sub Machine Carbine is listed as 650.0 m/s, resulting in a muzzle energy of 550 J, ballistically similar to modern pistol cartridges. The cartridge, now officially known as 5.56×30mm MINSAS, offers an effective range of about 200 to 300 m, with effective penetration against body armor. The early carbines for this round, known as MINSAS, were based on the INSAS rifle.
