ghost-of-gold:Lahti L-39 “Norsupyssy” anti-tank rifle (Finland)The Lahti L-39 is a Finnish 20 mm anti-tank rifle used during the Second World War. It had excellent accuracy, penetration and range, but its size made transportation difficult. It was nicknamed “Norsupyssy” (“Elephant Gun”), and as tanks developed armour too thick to be penetrated by even this large, powerful rifle, its uses switched to long range sniping, tank harassment and with the L-39/44 fully automatic variant, an improvised anti-aircraft weapon.The big ski like bipod under the rifle is presumably so the heavy rifle at one hundred Lb’s can be dragged along instead of being carried. It had a ten round box magazine that added an additional eight lbs of weight to the rifle. The Lahti L39 had a muzzle velocity of 2,625 feet per second and was positively awesome at close range.Below is an image to illustrate the size of a modern 20mm round, standing next to the more common big caliber rifle rounds. Have no misconceptions…these things are big! 20mm cannon rounds usually have the bullets painted bright blue, with a description of the dimensions and type of cartridge painted on it in white letters.Left to right: .223 - .338 Lapua Magnum - .50 cal Browning and finally the awesome 20mm cannon round. The Barrett Light 50 has a reputation as being an awesome man stopper, the 20mm however, literally blows that away.
