A double-barreled shotgun is a break-action shotgun with two parallel barrels, assuasive 2 unmarried shots to be fired in quick succession.

Construction [edit]

Modernistic double-barreled shotguns, oft known as doubles, are almost universally intermission action, with the barrels hinge downwardly at the rear to betrayal the breech ends for unloading and reloading. Since there is no reciprocating action needed to eject and reload the shells, doubles are more meaty than repeating designs such equally pump activeness, lever action, bolt action, or self-loading shotguns.

Barrel configuration [edit]

Double-barreled shotguns come in two bones configurations:

• side-by-side (Due south×South) — the two barrels are arranged horizontally;
• over-and-under (O/U) — the two barrels are arranged vertically.

The original double-barreled guns were virtually all S×South designs, which was a more than practical design for muzzleloaders. Early on cartridge-firing shotguns also used the S×S activeness, because they kept the exposed hammers of the earlier muzzleloading shotguns from which they evolved. When hammerless designs started to get mutual, the O/U blueprint was introduced, and most modern sporting doubles are O/U designs.^[ane]

One significant reward that doubles take over single-butt repeating shotguns is the ability to have more than 1 choke at a time. Some shotgun shooting sports, such as skeet shooting, use crossing targets presented in a narrow range of altitude, and just crave one level of choke. Other sports, like sporting clays, requite the shooter targets at differing ranges, and targets that might approach or recede from the shooter, and so must be engaged at differing ranges. Having 2 barrels lets the shooter use a more than open choke for near targets, and a tighter choke for distant targets, providing the optimal shot design for each distance.

The disadvantage lies in the fact that the barrels of a double-barreled shotgun, whether O/U or Due south×S, are not parallel, merely slightly angled,^{[ citation needed ]} so that shots from the barrels converge, commonly at "forty yards out". For the S×S configuration, the shotstring continues on its path to the opposite side of the rib after the converging point; for example, the left barrel'south discharge travels on the left of the rib till information technology hits expressionless center at 40 yards out, afterward that, the discharge continues on to the right. In the O/U configuration with a parallel rib, both barrels' discharges volition keep to the dead center, simply the discharge from the "under" barrel will shoot higher than the belch from the "over" butt afterward 40 yards. Thus, double-barreled shotguns are authentic only at practical shotgun ranges, though the range of their ammunition easily exceeds four to vi times that distance.

South×Due south shotguns are often more expensive, and may take more practice to aim effectively than a O/U. The off-eye nature of the recoil in a S×S gun may make shooting the torso-side barrel slightly more painful by comparison to an O/U, single-shot, or pump/lever action shotgun. Gas-operated, and to a lesser extent recoil-operated, designs will recoil less than either. More South×S than O/U guns have traditional "bandage-off" stocks, where the cease of the buttstock veers slightly to the correct, assuasive a correct-handed user to signal the gun more easily.^[ane]

Double-barreled shotguns are besides inherently more than safe, as whether the shotgun is loaded or tin be fired tin can be ascertained by anyone present if the action is broken open up, for case on a skeet, trap or hunting clays class when another shooter is firing; if the activity is open, the gun cannot burn down. Similarly, doubles are more easily examined to see if loaded than pump or semi-automatic shotguns, whose bolt must be opened and chamber closely examined or felt to make sure it is unloaded; with a double gun (or a interruption-activity unmarried gun), whether the gun is loaded, i.eastward., has cartridges in any bedchamber, is easily and immediately seen with a glance (and only equally easily unloaded).^{[ citation needed ]}

Trigger mechanism [edit]

The early doubles used two triggers, ane for each barrel, located forepart to back inside the trigger guard. The index finger was used to pull either trigger, as having two fingers inside the trigger guard can crusade a very undesirable recoil-induced double-discharge. Double-trigger designs are typically set up for right-handed users.^[1] In double-trigger designs, it is oft possible to pull both triggers at once, firing both barrels simultaneously, though this is generally not recommended equally it doubles the recoil, battering both shotgun and shooter, specially if information technology was unanticipated or unintended. Discharging both barrels at the same time has long been a hunting trick employed by hunters using eight gauge "elephant" shotguns, firing the two two-ounce slugs for sheer stopping power at close range.^{[ citation needed ]}

Afterward models apply a single trigger that alternately fires both barrels, called a single selective trigger or SST. The SST does not allow firing both barrels at one time, since the single trigger must be pulled twice in order to fire both barrels. The alter from one butt to the other may exist done by a clockwork blazon system, where a cam alternates between barrels, or by an inertial system where the recoil of firing the showtime barrel toggles the trigger to the next butt. A double-barreled shotgun with an inertial trigger works best with full power shotshells; shooting depression recoil shotshells oftentimes will not reliably toggle the inertial trigger, causing an apparent failure to fire occasionally when attempting to depress the trigger a second fourth dimension to burn down the 2d barrel (this also can happen if the first shell fails to burn down). Generally there is a method of selecting the order in which the barrels of an SST shotgun fire; commonly this is done through manipulation of the safety, pushing to one side to select top barrel first and the other side to select bottom barrel first. In the effect that an inertial trigger does not toggle to the second butt when firing low recoil shotshells, manually selecting the social club to the second barrel will enable the 2nd barrel to fire when the trigger is depressed again.

One of the advantages of double-barreled shotgun with double triggers or SST, is that the 2d shot can be taken almost immediately after the first with merely a 2d trigger pull, without needing to manually operate the action (which will inevitably destabilize the gun from the shoulder position and affect aim), and can utilize different chokes for the two shots (assuming, of grade, that total power shotshells are fired, at least for a double-barreled shotgun with an inertial type SST, as needed to toggle the inertial trigger). This can be noticeably faster than a pump shotgun, which requires manually pumping the fore-end to squirt and reload for the 2nd shot, and may exist faster, or not slower, than a semi-automatic shotgun (as there are no bolt movements to delay the rechambering of a second beat out). Note, however, in neither the pump or semi-automatic will the 2nd shot be a dissimilar choke pattern from the showtime shot, whereas for a double, the two shots are usually with different chokes. Thus, depending on the nature of the chase, the appropriate choke for the shot is always at mitt. For example, while field hunting flushing birds, the kickoff shot is ordinarily closer than the 2d considering the bird flies away from the shooter; then, the more open up choke (and butt) would exist better for the kickoff shot, and if a second shot is needed, as the bird is flying away, the more closed (and thus longer distance of an effective shot blueprint) choke (and barrel) is and then appropriate. Conversely, on a driven hunt, where the birds are driven towards the shooter, the airtight (longer constructive altitude) choke (and barrel) should be fired start, saving the open (closer effective altitude) choke (and barrel) for the at present-closer incoming bird. None of this is possible with unmarried-barrel shotguns, merely with a double, whether S×S or O/U.

Regulation [edit]

Regulation is a term used for multi-barreled firearms that indicates how close to the aforementioned point of aim the barrels volition shoot. A poorly regulated gun may hit consistently with one butt, but miss consistently with the other, making the gun nearly useless for anything requiring two shots. However, the short ranges and spread of shot provide a significant overlap, so a minor error in regulation in a double is often also small to exist noticed. Mostly the shotguns are regulated to hit the point of aim at a given distance, usually the maximum expected range since that is the range at which a full choke is used, and where precise regulation matters most. The regulation is ordinarily more than important in SxS shotguns, as felt recoil differs.
