The barrel of a Gun or other Firearm is the tube, usually Metal , through which a controlled Explosion is released in order to propel a Projectile out of the end at great speed. The first guns were made in a time where Metallurgy was not quite what it is today, so the pipe needed to be braced periodically along its length, producing an appearance somewhat reminiscent of a barrel. Another explanation, tied to etymology, states that many very first firearms barrels where in fact realized, during the 12-13 century, using small Storage Barrels with their usual metal rings reinforced by leather, hence the ''barrel'' name. In fact a set of old French words, some of them staying in modern French, were used as root words for various English firearms (and storage barrels) -related terms. The old French '' Gonne '' (pronounced by a French speaker it sounds approximately as ''gun'' does when pronounced by an English speaker) was a small barrel used on merchant and military ships. Likewise a ''baril'' was, as soon as in approx 1320 (used in ''Du Chevalier au barisel''), and remains now, a big barrel. Moreover the big Tun English barrel is, as stated in Ton , the French old and contemporary ''tonne'' barrel. CONSTRUCTION Modern day gun barrels are sophisticated in their construction and makeup. A gun barrel must be able to hold in the expanding gas produced by the Propellant to ensure that optimum Muzzle Velocity is attained by the Bullet or shell as it is being pushed out by the expanding gas(es). Early Firearms were mostly Muzzle Loading (loaded from the mouth rather than the breech), which tends to be a slow and complicated procedure, resulting in a low rate of fire. Breech Loading provided a higher rate of fire, but early breech loading guns lacked an effective way of sealing the escaping gases that leaked from the back end of the barrel; resulting in a lower muzzle velocity. During the 19th century, effective mechanical locks were invented that allowed loading from the breech while effectively sealing the breech from escaping propellant gases. |
