A shotgun shell, shotshell or just shell is a blazon of rimmed, cylindrical (straight-walled) cartridges used specifically by shotguns, and is typically loaded with numerous small-scale, pellet-like spherical sub-projectiles chosen shot, fired through a smoothbore barrel with a tapered constriction at the muzzle to regulate the extent of scattering. A shell tin can sometimes also contain only a single big solid projectile known every bit a slug, fired usually through a rifled slug barrel. The shell casing usually consist of a paper or plastic tube mounted on a brass base of operations holding a primer, and the shots are typically contained by a wadding/sabot inside the case.^[i] The caliber of the shotshell is known as its gauge.

The projectiles are traditionally made of lead, but other metals such as steel, tungsten and bismuth are also used due to restrictions on lead,^[two] and other unusual projectiles such every bit saboted flechettes, rubber assurance, rock salt and magnesium shards as well be. Slug shells can also exist made with specialty not-lethal projectiles such as condom and bean bag rounds.

Shotguns have an effective range of near 35 m (38 yd) with buckshot, 45 yard (49 yd) with birdshot, 100 m (110 yd) with slugs, and well over 150 thousand (160 yd) with saboted slugs in rifled barrels.^{[3] [4] [v]}

Other rounds include:

• Ferret rounds: rounds designed to penetrate a thin barrier (e.m. a car door) and release a gas payload.
• Bolo rounds: 2 large pb balls fastened by a wire.
• Piranha rounds: shells full of sharp tacks.
• Dragon's breath rounds: shells full of incendiary chemicals that creates a fireball/flame when discharged, and can ignite a flammable target at close range.

Most shotgun shells are designed to exist fired from a smoothbore butt, only dedicated shotguns with rifled barrels are limited to lead slugs or sabot slugs as "shot" would exist spread too wide by the rifling. A rifled barrel will increment the accuracy of sabot slugs, just makes it unsuitable for firing shot, as it imparts a spin to the shot loving cup, causing the shot cluster to disperse. A rifled slug uses rifling on the slug itself so it tin can be used in a smoothbore shotgun.

History [edit]

Early shotgun shells used brass cases, not unlike burglarize and pistol cartridge cases of the same era. These brass shotgun hulls or cases closely resembled burglarize cartridges, in terms of both the head and primer portions of the shotgun shell, equally well as in their dimensions. Menu wads, made of felt, leather, and cork, as well as paperboard, were all used at various times. Waterglass (Sodium silicate) was commonly used to cement the superlative overshot wad into these contumely shell casings. No roll crimp or fold crimp was used on these early on brass cases, although roll crimps were eventually used by some manufacturers to hold the overshot wad in place deeply. The primers on these early shotgun shells were identical to pistol primers of the same diameter.

Starting in the belatedly 1870s, newspaper hulls began replacing brass hulls. Newspaper hulls remained popular for almost a century, until the early 1960s. These shotgun shells using paper hulls were nearly always ringlet crimped, although fold crimping also somewhen became pop. The primers on these newspaper hull shotgun shells also inverse from the pistol primers used on the early contumely shotgun shells to a primer containing both the priming charge and an anvil, unlike rifle and pistol armament, making the shotgun shell primer taller. Carte wads, made of felt and cork, as well as paperboard, were all used at diverse times, gradually giving way to plastic over pulverisation wads, with bill of fare wads, and, eventually, to all plastic wads. Starting in the early 1960s, plastic hulls started replacing paper hulls for the majority of shotgun shells and by the 1980s, plastic hulls had become universally adopted.

Typical construction [edit]

Modern shotgun shells typically consist of a plastic example, with the base covered in a sparse brass plated steel covering. As noted previously, paper shells used to be common, and are still made, as are solid brass shells. Some companies have produced what announced to be all-plastic shells, although in these there is a pocket-size metallic ring bandage into the rim of the shell to provide strength. Oft the more powerful loads will use "high brass" shells, with the brass extended upward further forth the sides of the shell, while light loads will utilise "low brass" shells. The contumely does non actually provide a significant amount of strength, but the divergence in appearance provides shooters with a fashion to quickly differentiate between high and low powered armament.

A 1908 delineation of a shotgun vanquish, showing a primitive felt wad to separate the powder (left) and shot (right)

The base of the crush is fairly thick to hold the large shotgun primer, which is longer than primers used for rifle and pistol ammunition. Modernistic smokeless powders are far more efficient than the original black powder used in shotgun shells, so very little infinite is actually taken past powder; shotguns use modest quantities of double base powders, equivalent to quick-burning pistol powders, with up to 50% nitroglycerin. Later the pulverisation comes the wadding or wad. The primary purpose of a wad is to forbid the shot and powder from mixing, and to provide a seal that prevents gas from blowing through the shot rather than propelling information technology. The wad design may also encompass a stupor absorber and a cup that holds the shot together until it is out of the barrel.

A modernistic wad consists of three parts, the powder wad, the cushion, and the shot cup, which may exist separate pieces or be one office. The pulverisation wad acts equally the gas seal (known as obturation), and is placed firmly over the powder; it may be a paper or plastic part. The cushion comes next, and it is designed to shrink nether pressure, to deed as a shock cushion and minimize the deformation of the shot; information technology also serves to take upwardly as much space as is needed between the pulverization wad and the shot. Cushions are almost universally made of plastic with crumple zones, although for game shooting in areas grazed by farm stock or wildlife biodegradable fiber wads are often preferred. The shot cup is the terminal function of the shell, and information technology serves to hold the shot together as it moves down the barrel. Shot cups have slits on the sides so that they peel open after leaving the barrel, allowing the shot to continue on in flight undisturbed. Shot cups, where used, are as well almost universally plastic. The shot fills the shot cup (which must be of the correct length to hold the desired quantity of shot), and the shotgun shell is then crimped, or rolled closed.

Sizes [edit]

Shotgun vanquish comparison (left to right): 12-guess, 20-guess, 16-gauge, 28-gauge, and .410 bore

Standard [edit]

Gauge (number of pb balls in one pound)	Diameter of 1 ball
	inch	millimetre
ten	0.775	xix.7
12	0.729	18.5
sixteen	0.663	16.8
20	0.615	15.6
28	0.550	fourteen.0

Shotgun shells are more often than not measured by "gauge", which is the weight, in fractions of a pound, of a pure atomic number 82 round brawl that is the same diameter as the internal diameter of the barrel; in Britain and another locations outside the United states of america the term "diameter" is used with the same pregnant.^[v] This contrasts with rifles and handguns, which are almost ever measured in "caliber", a measurement of the internal bore of the barrel measured in millimeters or inches and, consequently, is approximately equal to the diameter of the projectile that is fired.

For case, a shotgun is called "12-gauge" because a lead sphere that simply fits the inside diameter of the barrel weighs 1⁄12 pound (38 thousand). This measurement comes from the time when early cannons were designated in a similar way—a "12 pounder" would be a cannon that fired a 12-pound (five.four kg) missive; inversely, an private "12-gauge" shot would in fact be a 1⁄12 pounder. Thus, a ten-gauge shotgun has a larger-diameter butt than a 12-approximate shotgun, which has a larger-bore barrel than a 20-gauge shotgun, and so forth.

The most popular shotgun gauge by far is 12-gauge. The larger 10-gauge, once popular for hunting larger birds such as goose and turkey, is in the decline with the advent of longer, "magnum" 12-gauge shells, which offer similar performance. The mid-size 20-estimate is besides a very popular chambering for smaller-framed shooters who favor its reduced recoil, those hunting smaller game, and experienced trap and skeet shooters who like the boosted claiming of hitting their targets with a smaller shot accuse. Other less-mutual, simply commercially available gauges are sixteen and 28. Several other gauges may exist encountered only are considered obsolete. The iv, 8, 24, and 32 gauge guns are collector items. There are as well some shotguns measured past bore, rather than gauge. These are the .410 (10.4mm), .380 (9mm), and .22 (5.5mm); these are correctly called ".410 bore", not ".410-guess".

The .410 diameter is the smallest shotgun size which is widely bachelor commercially in the United States. For size comparison purposes, the .410, when measured by gauge, would be effectually 67- or 68-gauge (it is 67.62-gauge), The .410 is often mistakenly assigned 36-guess. The 36 gauge was in fact a .360 diameter cartridge which was one.5 inches (38 mm) in length and is at present obsolete.

Other calibers [edit]

CCI .22LR snake shot loaded with #12 shot

Snake shot (AKA: bird shot, rat shot and grit shot)^[6] refers to handgun and rifle cartridges loaded with pocket-sized atomic number 82 shot. Snake shot is generally used for shooting at snakes, rodents, birds, and other pest at very shut range. The almost common serpent shot cartridges are .22 Long Rifle, .22 Magnum, .38 Special, 9×19mm Luger, .twoscore Smith & Wesson, .44 Special, .45 ACP, and .45 Colt.

Unremarkably used past hikers, backpackers and campers, serpent shot is ideally suited for employ in revolvers and derringers, chambered for .38 Special and .357 Magnum. Ophidian shot may not wheel properly in semi-automated pistols. Rifles specifically made to fire .22 caliber ophidian shot are likewise commonly used past farmers for pest control inside of barns and sheds, as the snake shot volition not shoot holes in the roof or walls, or more importantly injure livestock with a ricochet. They are too used for airport and warehouse pest control.^[vii]

Military Issue .45 ACP M15 "shot shell" on the far right.

Shot shells have also been historically issued to soldiers, to be used in standard issue rifles. The .45-70 "Forager" round, which contained a sparse wooden bullet filled with birdshot, was intended for hunting small-scale game to supplement the soldiers' rations.^{[8] [9]} This round in effect fabricated the .45-70 rifle into a small gauge shotgun, capable of killing rabbits, ducks, and other small game.

During Earth War II, the Usa armed services developed the .45 ACP M12 and M15 shot shells cartridges. They were issued to pilots, to exist used as foraging armament in the event that they were shot downward. While they were best used in the M1917 revolvers, the M15 cartridge would actually bike the semi-automated M1911 pistols action.

Garden guns [edit]

Garden guns are shine-bore firearms specifically fabricated to fire .22 caliber snake shot, and are ordinarily used by gardeners and farmers for pest control. Garden guns are brusk-range weapons that can practice piddling damage past 15 to 20 yards, and they are quiet when fired with snake shot, compared to a standard armament. These guns are especially effective inside of barns and sheds, as the snake shot will not shoot holes in the roof or walls, or more importantly injure livestock with a ricochet. They are as well used for pest control at airports, warehouses, stockyards, etc.^[7]

Shotgun judge bore formula [edit]

The standard definition of shotgun gauge assumes that a pure lead brawl is used. The following formulas relate the bore diameter d_n (in inches) to the gauge northward:

${\displaystyle d_{n}=i.67/{\sqrt[{3}]{n}}={\sqrt[{3}]{four.66/n}}}$

${\displaystyle n=(1.67/d_{n})^{3}=iv.66/(d_{northward})^{3}}$

For example, the common bore diameter d_north = 0.410 inches (.410 bore) is finer gauge due north = 67.vi .

Lead free [edit]

Past 1957 the ammo industry had the capability of producing a nontoxic shot, fabricated out of either iron or steel.^[10] In 1976 the Fish and Wild fauna Service took the first steps toward phasing out pb shot past designating steel-shot-only hunting zones for waterfowl. In the 1970s lead-free shot crush ammunition loaded with steel, bismuth, or tungsten composite pellets instead of more traditional lead-based pellets was introduced and required for Migratory Bird Hunting (Ducks & Geese). Lead shot in waterfowl hunting was banned throughout the United states of america in 1991.^{[xi] [12]} Due to ecology regulations, lead-loaded ammunition must exist used advisedly by hunters in Europe. For instance, in France, it cannot exist fired in the vicinity of a swimming. In fact, the laws are so complex that some hunters in Europe prefer non to take chances getting into problems for firing lead pellets in the wrong places, and so they opt for blended pellets in all situations. The use of lead shot is banned in Canada and the United states when hunting migratory game birds, such as ducks and geese, forcing the use of non-toxic shot in these countries for waterfowl hunting (atomic number 82 shot tin can still legally exist used in the The states for hunting game other than waterfowl). This means that manufacturers need to market new types of lead-gratis shotgun ammunition loaded with culling pellets to meet environmental restrictions on the utilize of lead, as well as lead-based and cheaper shotshell ammunition, to remain competitive worldwide.

The C.I.P. enforces blessing of all ammunition a manufacturer or importer intends to sell in any of the (mainly European) C.I.P. member states. The ammunition manufacturing plants are obliged to test their products during product against the C.I.P. pressure specifications. A compliance study must be issued for each production lot and archived for later verification if needed.

Likewise pressure testing, shotshells containing steel pellets require an additional Vickers hardness test. The steel pellets used must have a hardness nether 100 HV1, just, fifty-fifty so, steel is known to wearable the butt excessively over time if the steel pellet velocities get too high, leading to potentially harmful situations for the user. Every bit a result, the measurement of pellet velocity is too an additional obligation for shotshells in 12-, 16-, and 20-gauges in both standard and high performance versions sold in Europe. The velocity of pellets must be below 425 m/s (ane,390 ft/s), 390 g/s (one,300 ft/due south) and 390 m/southward (one,300 ft/s) respectively for the standard versions. Another disadvantage of steel pellets is their tendency to ricochet unpredictably after striking any hard surface. This poses a major hazard at indoor ranges or whenever metal targets or difficult backstops (e.k. concrete wall vs. a clay berm) are used. For this reason, steel shot is explicitly banned at most indoor shooting ranges. Any shooters who are considering buying ammo loaded with steel for anything other than hunting purposes should start notice out if using it won't cause undue run a risk to themselves and others.^{[ commendation needed ]}

Notwithstanding, information supporting the danger of firing loftier velocity shells loaded with steel shot causing barrel clothing has not been published and the U.s.a. equivalent of CIP, SAAMI, does not accept any such restrictive limitations on the velocity of commercial steel shotshells sold in the United States. Similarly, shotgun manufacturers selling shotguns in the U.s.a. select their own appropriate standards for setting steel hardness for shotgun barrels and for velocities of steel shotshell loaded ammunition.

Some indoor shooting ranges prohibit the use of steel shot over concern of it causing a spark when hit an object down range and causing a fire.^{[ citation needed ]}

Shot sizes [edit]

Shotshells are loaded with different sizes of shot depending on the target. For skeet shooting, a small shot such as a No.8 or No.9 would be used, because range is brusque and a loftier density pattern is desirable. Trap shooting requires longer shots, and so a larger shot, usually #vii½ is used. For hunting game, the range and penetration needed to assure a clean kill is considered. Shot loses its velocity very quickly due to its low sectional density and ballistic coefficient (run across external ballistics). Small-scale shot, like that used for skeet and trap, will have lost all appreciable free energy past around 100 yards (91 m), which is why trap and skeet ranges can be located in relatively close proximity to inhabited areas with negligible run a risk of injury to those outside the range.

Birdshot [edit]

"Birdshot" redirects here. For the 2022 Philippine film, run into Birdshot (film).

12-gauge birdshot shotgun shell.

Birdshots are designed to be used for waterfowl and upland hunting, where the game is active small/medium-sized birds. Their sizes are numbered like to the shotgun gauges—the smaller the number, the larger the shot (except in the obsolete Swedish arrangement, in which information technology is reversed). Mostly birdshot is just called "shot", such equally "number 9 shot" or "BB shot".

There are small differences in size of American, Standard (European), Belgian, Italian, Norwegian, Castilian, Swedish, British, and Australian shot to make matters more complex. That is because some systems go by diameter in inches (American), some go by diameter in millimeters (European), and the British system goes by the number of lead shot per ounce. Australia has a hybrid system due to its market beingness flooded with a mixture of British, American, and European shells.

For American shot, a useful method for remembering the diameter of numbered shot in inches is only to subtract the shot size from 17. The resulting answer is the diameter of the shot in hundredths of an inch. For example, #2 shot gives 17-2 = 15, pregnant that the diameter of #2 shot is 15/100 or 0.15". B shot is .170 inches, and sizes go upward in .01 increments for BB and BBB sizes.

In metric measurement, information technology is piece of cake to recall that #5 shot is 3 mm; each number up or down represents a 0.25 mm change in bore, then e.g. #vii shot is 2.5 mm.

Number 11 and number 12 atomic number 82 shot too exists. Shot of these sizes is used in specialized shotshells designed to be fired at close range (less than four yards) for killing snakes, rats and similar-sized animals. Such shells are typically intended to exist fired from handguns, particularly revolvers.^[14] This blazon of ammunition is produced by Federal and CCI, among others.

For hunting, shot size must be chosen non only for the range, merely besides for the game. The shot must reach the target with enough energy to penetrate to a depth sufficient to impale the game. Lead shot is still the all-time ballistic performer, but environmental restrictions on the use of lead, specially with waterfowl, require steel, bismuth, or tungsten composites. Steel, existence significantly less dumbo than lead, requires larger shot sizes, but is a good choice when lead is not legal and cost is a consideration. Information technology is argued that steel shot cannot safely be used in some older shotguns without causing damage to either the bore or to the choke due to the hardness of steel shot. However, the increased pressure level in most steel cartridges is a far greater problem, causing more than strain to the breech of the gun. Since tungsten is very hard, it must as well be used with care in older guns. Tungsten shot is oftentimes assimilated with nickel and iron, softening the base metal. That alloy is approximately i/3 denser than atomic number 82, simply far more expensive. Bismuth shot falls betwixt steel and tungsten shot in both density and toll. The rule of thumb in converting appropriate steel shot is to become upward by ii numbers when switching from lead. Withal, in that location are different views on dense patterns versus higher pellet energies.

Buckshot [edit]

Larger sizes of shot, large plenty that they must be carefully packed into the beat rather than merely dumped or poured in, are chosen "buckshot" or just "buck". Buckshot is used for hunting medium to big game, equally a tactical round for law enforcement and military personnel, and for personal cocky-defense. Buckshot size is virtually usually designated by a series of numbers and messages, with smaller numbers indicating larger shot. Sizes larger than "0" are designated by multiple zeros. "00" (usually pronounced "double-null" in N American English) is the most commonly sold size.

The British organisation for designating buckshot size is based on the amount of shot per ounce. The sizes are LG (large grape – from grapeshot derived from musket shooting), MG (medium grape), and SG (small grape). For smaller game, SSG shot is one-half the weight of SG, SSSG shot is one-half the weight of SSG, SSSSG shot is half the weight of SSSG, and then on. The Australian system is similar, except that it has 00-SG, a pocket-sized-game shell filled with 00 buckshot.

Loads of 12-judge 00 buckshot are commonly available in cartridges belongings from 8 (viii) to eighteen (18) pellets in standard shell lengths (2+ 3⁄4 inches, 3 inches, and 3+ ane⁄2 ). Reduced-recoil 00 buckshot shells are often used equally tactical and self-defense force rounds, minimizing shooter stress and improving the speed of follow-up shots.

Spread and patterning [edit]

Most modernistic sporting shotguns accept interchangeable asphyxiate tubes to allow the shooter to change the spread of shot that comes out of the gun. In some cases, information technology is not practical to do this; the gun might have fixed choke, or a shooter firing at receding targets may want to burn down a wide blueprint immediately followed by a narrower pattern out of a single barrelled shotgun. The spread of the shot tin also be altered by changing the characteristics of the shell.

Narrower patterns [edit]

A buffering material, such as granulated plastic,^[17] sawdust, or similar fabric tin be mixed with the shot to fill the spaces between the individual pellets. When fired, the buffering material compresses and supports the shot, reducing the deformation the shot pellets feel under the farthermost dispatch. Antimony-lead alloys, copper plated atomic number 82 shot, steel, bismuth, and tungsten composite shot all have a hardness greater than that of plain lead shot, and will deform less as well. Reducing the deformation will consequence in tighter patterns, as the spherical pellets tend to fly straighter. I improvised method for achieving the same upshot involves pouring molten wax or tar into the mass of shot.^[17] Another is a partial ring cut around the case intended to ensure that the shot comes out tightly bunched along with the portion of the case forward of the cutting, creating a 'cutting-shell'.^[18] This can exist dangerous, every bit information technology is idea to cause college chamber pressures—specially if part of the trounce remains behind in the barrel and is non cleared before another shot is fired.^{[18] [19]}

Wider patterns [edit]

Shooting the softest possible shot will result in more shot deformation and a wider pattern. This is often the case with cheap ammunition, as the lead used will have minimal alloying elements such as antimony and be very soft. Spreader wads are wads that have a small plastic or paper insert in the middle of the shot cup, commonly a cylinder or "X" cross-section. When the shot exits the barrel, the insert helps to push the shot out from the center, opening upwards the pattern. Oftentimes these result in inconsistent performance, though modern designs are doing much better than the traditional improvised solutions. Intentionally plain-featured shot (hammered into ellipsoidal shape) or cubical shot will also result in a wider pattern, much wider than spherical shot, with more consistency than spreader wads. Spreader wads and non-spherical shot are disallowed in some competitions. Hunting loads that use either spreaders or not-spherical shot are commonly called "brush loads", and are favored for hunting in areas where dense comprehend keeps shot distances very short.

Spread [edit]

Near shotgun shells contain multiple pellets in order to increase the likelihood of a target being striking. A shotgun'southward shot spread refers to the two-dimensional pattern that these projectiles (or shot) leave behind on a target.^[14] Another less important dimension of spread concerns the length of the in-flight shot string from the leading pellet to the abaft one. The utilise of multiple pellets is especially useful for hunting small game such every bit birds, rabbits, and other animals that fly or move quickly and tin can unpredictably change their direction of travel. However, some shotgun shells but contain one metal shot, known every bit a slug, for hunting big game such as deer.

Every bit the shot leaves the barrel upon firing, the three-dimensional shot cord is close together. Only every bit the shot moves further away, the private pellets increasingly spread out and disperse. Because of this, the effective range of a shotgun, when firing a multitude of shot, is limited to approximately xx to 50 m (22 to 55 yd). To control this effect, shooters may use a constriction inside the barrel of a shotgun called a choke. The choke, whether selectable or fixed within a barrel, effectively reduces the diameter of the end of the butt, forcing the shot fifty-fifty closer together as it leaves the barrel, thereby increasing the effective range. The tighter the choke, the narrower the end of the barrel. Consequently, the effective range of a shotgun is increased with a tighter choke, equally the shot column is held tighter over longer ranges. Hunters or target shooters can install several types of chokes, on guns having selectable chokes, depending on the range at which their intended targets will exist located. For fixed choke shotguns, different shotguns or barrels are oftentimes selected for the intended hunting application at hand. From tightest to loosest, the diverse asphyxiate sizes are: full choke, improved modified, modified, improved cylinder, skeet, and cylinder bore.^[20]

A hunter who intends to chase an animal such every bit rabbit or bickering knows that the brute volition be encountered at a shut range—ordinarily within 20 m (22 yd)—and will be moving very rapidly. So, an ideal choke would be a cylinder bore (the loosest) equally the hunter wants the shot to spread out as quickly as possible. If this hunter were using a full choke (the tightest) at 20 m (22 yd), the shot would exist very close together and crusade an unnecessarily large amount of harm to the rabbit, or, alternatively, a complete miss of the rabbit. This would waste nearly all of the meat for a striking, as the piddling amount of meat remaining would exist overly-laden with shot and rendered inedible. By using a cylinder bore, this hunter would maximize the likelihood of a kill, and maximize the amount of edible meat. Contrarily, a hunter who intends to hunt geese knows that a goose will likely be approximately 50 k (55 yd) away, then that hunter would want to delay the spread of the shot every bit much every bit possible past using a full choke. By using a full choke for targets that are farther away, the shooter again maximizes the likelihood of a kill, and maximizes the corporeality of edible meat. This also guarantees a swift and humane kill as the target would be hit with plenty shot to impale chop-chop instead of but wounding the beast.

For older shotguns having only one stock-still asphyxiate, intended primarily for equally likely use confronting rabbits, squirrels, quail, doves, and pheasant, an often-called asphyxiate is the improved cylinder, in a 28 inches (710 mm) butt, making the shotgun suitable for use as a full general all-round hunting shotgun, without having backlog weight. Shotguns having fixed chokes intended for geese, in contrast, are oft found with full choke barrels, in longer lengths, and are much heavier, being intended for fixed use within a bullheaded confronting afar targets. Defensive shotguns with stock-still chokes more often than not have a cylinder diameter choke. Besides, shotguns intended primarily for use with slugs invariably also are found with a choke that is a cylinder bore.

Dram equivalence [edit]

"Dram" equivalence is sometimes even so used every bit a measure of the pulverization charge ability in a shotgun vanquish. Today, it is an anachronistic equivalence that represents the equivalent ability of a shotgun shell containing this equivalent corporeality of black-powder measured in drams avoirdupois.^[21] A dram in the avoirdupois system is the mass of 1⁄256  pound or one⁄16  ounce or 27.3 grains. The reasoning behind this archaic equivalence is that when smokeless powder start came out, some method of establishing an equivalence with mutual shotgun shell loads was needed in society to sell a box of shotgun shells. For case, a shotgun trounce containing a 3 or 3 1/2 dram load of blackness-powder was a common hunting field load, and a heavy full power load would take contained about a 4 to 4-1/two dram load, whereas a shotgun shell containing only a 2 dram load of black-powder was a common target do load. A hunter looking for a field or full power load familiar with black-powder shotgun loads would take known exactly what the equivalence of the shotgun shells would have been in the newly introduced smokeless powder. Today, however, this represents a poorly understood equivalence of the powder accuse power in a shotgun shell. To further complicate matters, "dram" equivalence was only defined for 12 gauge shotgun shells, and only for lead shot, although information technology has oft been used for describing other gauges of shells, and fifty-fifty steel shot loaded shells. Furthermore, "dram" equivalence but came around about 15 years afterward smokeless pulverisation had been introduced, long after the need for an equivalence had started to fade, and actual black-powder loaded shotshells had largely vanished. In exercise, "dram" equivalence today almost commonly equates just to a velocity rating equivalence in fps (anxiety-per-second), while assuming atomic number 82 shot.

A secondary affect of this equivalence was that mutual shotgun shells needed to stay the same size, physically, e.g., ii-1/2 or 2-3/4-inch shells, in order to be used in pre-existing shotguns when smokeless powder started being used to load shotgun shells in the identify of black-powder. Equally smokeless powder did not accept to be loaded in the same volume as black-powder to achieve the same power, existence more powerful, the volumes of wads had to increase, to fill the shotgun shell enough to permit proper crimps still to exist made. Initially, this meant that increased numbers of over powder menu wads had to exist stacked to achieve the same stack-upwards length. Somewhen, this likewise led to the introduction of one-piece plastic wads in the tardily 1950s through the early 1960s, to add together boosted wad volumes, in order to maintain the same overall shotgun shell length.

Dram equivalence has no bearing on the reloading of shotgun shells with smokeless powder; loading a shotgun crush with an equivalent dram weight of smokeless pulverization would cause a shotgun to explode. It only has an equivalence in the reloading of shotgun shells with black powder.
