Double-Barrel Shotgun

A double-barreled shotgun is a shotgun with two parallel barrels, allowing two shots to be fired in quick succession. Modern double-barreled shotguns, often known as doubles, are almost universally break open actions, with the barrels tilting up at the rear to expose the breech ends of the barrels for unloading and reloading. Since there is no reciprocating action needed to eject and reload the shells, doubles are more compact than repeating designs such as pump action or lever-action shotguns.

Double-barreled shotguns come in two basic configurations: the side-by-side shotgun (SxS) and the over/under shotgun ("over and under", O/U, etc.), indicating the arrangement of barrels. The original double-barreled guns were nearly all SxS designs, which was a more practical design of muzzle-loading firearms. Early cartridge shotguns also used the SxS action, because they kept the exposed hammers of the earlier muzzle-loading shotguns from which they evolved. When hammerless designs started to become common, the O/U design was introduced, and most modern sporting doubles are O/U designs.

Both barrels of a double-barrel shotgun can be fired at once. The wielder rolls an additional Shooting die, just as when firing on Full-Auto (plus Wild Die), including recoil (which cancels out the usual +2 for shotguns). Roll damage for each successful shot separately.
