what size bullet does an ak 47 shoot
Comparison of the AK-47 and M16 The AK-47 was finalized, adopted and entered widespread service in the Soviet Army in the early 1950s.[27] Its firepower, ease of use, low production costs, and reliability were perfectly suited for the Soviet Army's new mobile warfare doctrines. More AK-type weapons have been produced than all other assault rifles combined.[28] In 1974, the Soviets began replacing their AK-47 and AKM rifles with a newer design, the AK-74, which uses 5.45×39mm ammunition.
.300 AAC Blackout The .300 AAC Blackout (designated as the 300 BLK by the SAAMI[1] and 300 AAC Blackout by the C.I.P.[2]), also known as 7.62×35mm is a carbine 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 7.62×39mm Soviet cartridge in an AR-15 while using standard AR-15 magazines at their normal capacity. It can be seen as a SAAMI-certified copy of J. D. Jones' wildcat .300 Whisper. Care should be taken not to use 300 BLK ammunition in a rifle chambered for 7.62×40mm Wilson Tactical.[3]
