A double barrel shotgun is a type of firearm that features two parallel barrels, allowing the shooter to fire two shots in quick succession. This design enhances the weapon's versatility, making it popular for hunting and sport shooting. The barrels can be arranged either side by side or one on top of the other, known as over-and-under configuration. These shotguns are typically loaded with shotgun shells, which contain multiple small pellets, making them effective for hitting moving targets like birds. Double barrel shotguns are often favored for their reliability and ease of use, appealing to both novice and experienced shooters alike.
