What is Barrel (weapons)?
[[Image:240mm howitzer.jpg|thumb|300px|A US 240 mm howitzer in use in 1944]] A '''barrel''' is a part of a [[gun]]. It is a long [[metal]] tube that the [[bullet]] or [[projectile]] goes through after it is fired. Guns can have many different sizes of barrels. Usually, longer barrels make it easier for the bullet to hit the [[bullseye (sports)|target]] more often. Barrels usually have [[spiral]] grooves on the inside called [[rifling]].<ref>{{cite web |url=http://www.dictionary.com/browse/rifling |title=rifling |publisher=Dictionary.com, LLC |access-date=28 July 2016}}</ref> Barrels with grooves spin the projectile around faster as it exits the gun.<ref name=fireguide>{{cite web |url=http://www.thefirearms.guide/guns/early-firearm-history |title=Early Firearms History |publisher=The Firearms Guide |access-date=28 July 2016 |archive-date=1 July 2016 |archive-url=https://web.archive.org/web/20160701114942/http://www.thefirearms.guide/guns/early-firearm-history |url-status=dead }}</ref> This makes the projectile more [[Stability|stable]] in flight and more [[accurate]].<ref name=fireguide/> == References == {{reflist}} [[Category:Firearm components]] {{military-stub}}
