The 5.45 cartrige was the result of the Soviet observations in Vietnam showing that the 5.56x45mm round used in the American M16s. The 5.56x45mm round was small and light weight allowing soldiers to carry more ammunition.
In response the Soviet Union created the 5.45x39mm M74 cartrige and adopted a new rifle for the cartrige the AK-74. The M74 replaced the M47 7.62x39mm cartridge as the standard Ridle cartridge in the Russian Military.
The Balisticls of the M74 round can cause tromendous wounds by a tumbling effect caused by the round creating a temporary cavity twice.
The M74 round is deadly and acurate. In the invasion of Afghanistan Soviet troops used the new round to great effect. The Mujahdeen called it the poison bullet because often when hit the victems wouldn't die from the initial hit. But would die later from wounds caused by the bullet.
