Thought the modern tactical .50 caliber rifles used by US Special Forces are big guns, well take a look at this vintage heavy rifle, the Russian PTRD-41. This is one heavy hitter of a weapon.
It is one of the original Russian Anti-Tank rifles that were used against the Nazis in World War 2, and also encountered by GIs in the Korean War in the hands of communist Chinese and North Korean soldiers.
The PTRD-41 is a beast of a gun, it and its improved models were used effectively by the Russians in World War 2 to destroy enemy light tanks, trucks, personnel and even turned against Nazi aircraft.
