US Army researchers are turning it 'up to 11' to make hypervelocity firearms | TechLink
Experimental firings were conducted in March with a cartridge that contained less than a gram of propellant (15 grains).
The muzzle velocity was over 2,900 feet per second,
"The goal is to get rifle-like velocities out of a very small weapon that is high capacity, that's either adaptable for room-clearing or confined spaces [doors/hatches etc]"
We have seen this before. The P-90 came about from such efforts. As did the Calico.
"... the U.S. Army's new 24-inch prototype barrel produced muzzle velocities of 4,600 to 5,750 feet per second.
The combustion chamber pressure was increased from 65 ksi to 100 ksi (100,000 pounds per square inch), almost double the pressure seen in the M4 carbine."
