Squeeze Bore
A squeeze bore, alternatively taper-bore, cone barrel or conical barrel, is a weapon where the internal gun barrel, barrel diameter progressively decreases towards the muzzle (firearms), muzzle, resulting in a reduced final internal diameter. These weapons are used in conjunction with special sub-caliber ammunition where the projectile is fitted with soft-metal flanges which fills out the caliber. As the projectile travels through the squeeze bore, the flanges fold inwards, resulting in a reduced caliber round with an increased velocity compared to a traditional full-caliber round. Mechanism A squeeze bore utilizes the energy of the propellant to squeeze the diameter of the bullet or shell (projectile), shell down, increasing penetration and velocity significantly. This process also means high chamber pressure and low barrel service life. For example, the service life of a squeeze bore 7.5 cm Pak 41 could be as low as 1000 rounds compared to 5000–7000 rounds for the 7.5 cm Pak 3 ...

Ordnance QF 2 Pounder
The Ordnance QF 2-pounder ( QF denoting "quick firing"), or simply "2 pounder gun", was a British anti-tank gun and vehicle-mounted gun employed in the Second World War. It was the main anti-tank weapon of the artillery units in the Battle of France and, due to the need to rearm quickly after the Dunkirk evacuation, remained in service during the North African campaign. In its vehicle-mounted variant the 2-pounder was a common main gun on British tanks early in World War II, as well as being a typical main armament of armoured cars, such as the Daimler, throughout the war. As the armour protection of Axis tanks improved, the 2-pounder lost effectiveness and it was gradually replaced by the 57 mm QF 6-pounder starting in 1942. It equipped infantry battalion anti-tank platoons replacing their anti-tank rifles until in turn replaced by 6-pounders but remained in service until the end of the war. This QF 2-pounder was distinctly different from the QF 2 pounder "pom-pom" gun ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Littlejohn Adaptor
The Littlejohn adaptor was a device that could be added to the British QF 2 pounder (40 mm) anti-tank gun. It was used to extend the service life of the 2-pounder during the Second World War by converting it to squeeze bore operation. "Littlejohn" came from the calque In linguistics, a calque () or loan translation is a word or phrase borrowed from another language by literal word-for-word or root-for-root translation. When used as a verb, "to calque" means to borrow a word or phrase from another language ..., i.e. literal anglicization, of the name of František Janeček, the Czech designer and factory owner who had been working on the squeeze-bore principle in the 1930s, and his son František Karel Janeček, who had brought his know-how to Britain after fleeing from German-occupied Czechoslovakia. Design The adaptor took the form of a reducing bore that was screwed on to the end of the gun. This was coupled with a round formed from a hard core ( tungsten) insi ...
