The .300 Blackout

Also known as 7.62×35 is an intermediate cartridge developed in the United States by Advanced Armament Corporation (AAC) for use in the M4 carbine.
Its purpose is to achieve ballistics similar to the 7.62x39mm cartridge or even more similarly the 7.92x33mm Kurz cartridge in an M4 while using standard M4 magazines at their normal capacities. 300 BLK ammunition cannot be used in a rifle chambered for 7.62x40mm Wilson Tactical.
It is mainly derived from the .300 Whisper concept but differs in certain areas.
