The forerunner to projectile based anti-tank weapons. Many coutries develpoed them. This was britians version. -------------------------------------------------- The Boys was the only anti-tank rifle to serve with the British Army. It was designed in the mid 1930's when this type of weapon was popular everywhere. It used a bolt action feeding from a top mounted magazine and it all it's parts were robust and heavy, but it did weight 36lb (16.5 kg) which was substantial load for one man to carry. The barrel and breech were mounted on a slide which recoiled along the top of the stock and so absorbed some of the considerable force from the firing a 0.55-in (14mm) round. A muzzle break was also fitted to reduce the recoil still further. The weapon was supported on a monopod at the front and this too has a form of shock absorber built into it. The round was developed from a big-game rifle cartridge and was specially designed and used a belted cartridge case to withstand the firing stresses. The bullet was steel cored, although later versions had a tungsten core. The armour penetration was never impressive and the Boys was virtually obsolete before it entered service. It did see action in France in 1940 and in Burma and Malaya in 1941-42. It was also mounted in armoured cars and Bren Gun carriers in Egypt and Libya in 1941, where it proofed a good anti-personnel weapon in rocky terrain when rock fragments were produced by indirect fire. It was eventually replaced by the PIAT in 1942. http://www.btinternet.com/~ian.a.paterson/equipinfantry.htm I remember reading somewhere that this was used as a sniper rifle by some units. Anyone know any details?
