Product Description

Tungsten Alloy TSS Shell 
 
TSS shell is a self-contained cartridge loaded with shot or a slug designed to be fired from a TSS. Most tss shells are designed to be fired from a smoothbore barrel, but with the recent gain in popularity of dedicated tsss with ed barrels for firing slugs, there are many rounds specifically designed to be fired from a ed barrel. A ed barrel will increase the accuracy of the tss with slugs, but makes it unsuitable for firing shot, as the ing causes the shot to form a hollow "O" shape in flight. Some less lethal tss ammunition is available in the form of slugs made of low-density material, such as rubber. See tss specialty ammunition for more information.
 
Construction of a typical TSS
 
Modern TSS  typically consist of a plastic case, with the base covered in a thin brass covering. Paper shells used to be common, and are still made, as are solid brass shells. Some companies have produced what appear to be all-plastic shells, although in these there is a small metal ring cast into the rim of the shell to provide strength. Often the more powerful loads will use "high brass" shells, with the brass extended up further along the sides of the shell, while light loads will use "low brass" shells. The brass does not actually provide a significant amount of strength, but the difference in appearance provides shooters with a way to quickly differentiate between high and low powered ammunition.
 
The base of the TSS is fairly thick to hold the large tss primer, which is quite a bit longer than primers used for e and pisto ammunition. Modern smokeless powders are far more efficient than the original black powder used in tss shells, so very little space is actually taken by powder; tsss use small quantities of powerful double base powders, equivalent to fast-burning pisto powders, with up to 50% nitroglycerin. After the powder comes the wadding. The primary purpose of a wad is to provide a gas seal, since without a wad the gas would just blow through the shot rather than propelling it. The wad consists of three parts, the powder wad, the cushion, and the shot cup, which may be separate pieces or be one part. The powder wad acts as 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 compress under pressure, to act as a shock absorber and minimize the deformation of the shot; it also serves to take up as much space as is needed between the powder 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 fibre wads are often preferred. The shot cup is the last part of the shell, and it 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 also 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 tss shell is then crimped closed.
 
Shotshell sizes
TSS shells are generally measured by "gauge," though in Britain and some other locations outside the United States the term "bore" is used with the same meaning. es and tsss are almost always measured in "caliber," which is simply a measurement of the internal diameter of the barrel and, consequently, the diameter of the projectile fired. By contrast, tsss are usually measured by "gauge," which is the weight, in fractions of a pound, of a lead round shot the same internal diameter as the barrel.
 
For example, a TSS is called 12 gauge because a lead sphere that just fits the inside diameter of the barrel weighs 112 of a pound. This measurement comes from the time when early cannons were designated in a similar manner-a "12 pounder" would be a cannon that fired a 12 pound (5.5 kg) cannonball; inversely, an individual "12 gauge" shot would in fact be a 112 pounder (38 g). Thus, a 10-gauge tss has a larger-diameter barrel than a 12-gauge tss, which has a larger-diameter barrel than a 20-gauge tss, and so forth.

The most popular tss 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-gauge is also 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 additional challenge of hitting their targets with a smaller shot charge. Other less-common, but commercially available gauges are 16 and 28. There are also some tsss measured by diameter, rather than gauge, these are the .410 (10 mm), .380 (9 mm), and .22 (5.5 mm); these are correctly called ".410 bore", not ".410 gauge".
 
The .410 bore is the smallest tss size which is widely available commercially,in the UK 9mm tsss are quite common for use in "GardenGuns" and folding tss. For size comparison purposes the .410, when measured by gauge, would be around 67 or 68 gauge (mathematically it's 67.62 gauge), not the sometimes mistakenly assigned 36 gauge.
TSS are also found in some tss cartridges, such as .38 Special and .44 Magnum; these are often used in revolvers for defense against snakes at very close ranges, or for killing small pests such as rats. A number of single shot pistos and es are made in .45 Colt with special screw-in chokes allowing the use of .410 shells-usually the chokes are designed with deep grooves parallel to the bore designed to stop the spin of the shot column, as the .45 Colt barrel is ed. Taurus recently introduced a revolver named The Judge, which accommodates both .45 Colt and .410 shotshells.
 
Tss Gauge Diameter Formulas
The first formula "Standard tss Gauge Diameter Formula" assumes the standard specific gravity (Density) for lead is 11.3523g/cm3 (see "Formula Research Notation" below to explain), and the second formula "Tss Gauge Diameter Formula 2" allows you to choose your own specific gravity for lead.
 
Standard Tss Gauge Diameter Formula
The following formula] will accurately calculate the diameter (dn) in inches of any tss gauge size (n).
or
tss Gauge Diameter Formula 2
For any tss gauge size (n), the following formula is used if you want to specify an alternate specific gravity (s) for lead in the calculation; e.g. 11.34 or 11.35 are the most common because they round to the nearest two decimal places.

Lead free tss
At the beginning of the 21st century lead free shotshell ammunition loaded with steel, bismuth, or tungsten composites pellets instead of more traditional lead based pellets was introduced. Due to environmental regulations, hunters in Europe are required to use lead loaded ammunition carefully. For instance, in France, they cannot fire in the vicinity of a pond. In fact, the laws are so complex that some hunters in Europe prefer not to risk getting into problems for firing lead pellets at wrong places, so they opt for steel, bismuth, or tungsten composites pellets in all situations. The use of lead shot is also banned in Canada when hunting migratory game birds, such as ducks and geese, forcing the use of non-toxic shot. This means that manufacturers need to market new types of lead free tss ammunition loaded with alternative pellets to meet environmental restrictions on the use of lead.
 
As with all ammunition the C.I.P. enforces the approval 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 production against the C.I.P. pressure specifications. A compliance report must be issued for each production lot and archived for later verification if needed. Besides pressure testing, shotshell using steel pellets requires an additional Vickers hardness test. The hardness VH1 must be below 100 for the used steel pellets but even so, steel is known to wear the barrel excessively over time if the pellets velocity becomes too high leading to potentially harmful situations for the user. As a result, the measurement of the pellets velocity is also an additional obligation for shotshell calibres 12, 16 and 20 in both standard and high performance versions. The pellets velocity must be below 425 m/s, 390 m/s and 390 m/s respectively for the standard versions.
 
Shot sizes
Shotshells are loaded with different sizes of shot depending on the target. For skeet shooting, a small shot such as a # 8 or #9 would be used, because range is short and a high density pattern is desirable. Trap shooting requires longer shots, and so a larger shot, up to #7½ would be desired. For hunting game, the range and the penetration needed to assure a clean kill must both be considered. Shot loses its velocity very quickly due to its low sectional density and ballistic coefficient (see external ballistics). Small shot, like that used for skeet and trap, will have lost all appreciable energy by 100 yards or meters, which is why trap and skeet ranges can be located in relatively close proximity to inhabited areas with negligible risk of injury to those outside the range.
 
Birdshot
12 gauge birdshot tss shell.
Birdshot sizes are numbered similar to the tss gauges; the smaller the number, the larger the shot. Generally birdshot is just called "shot", such as "number 9 shot" or "BB shot". A useful method for remembering the diameter of numbered birdshot is simply to subtract the shot size from 17. The resulting answer is the diameter of the shot in hundredths of an inch. For example, number 2 shot gives 17-2 = 15, meaning that the diameter of number 2 shot is 15/100 or 0.15". B shot is .170 inches, and sizes go up in .01 increments for BB and BBB or Pellets.

Birdshot selection
For hunting, shot size must be chosen not only for the range, but also for the game. The shot must reach the target with enough energy to penetrate to a depth sufficient to kill the game. Lead shot is still the best performer for the money, but environmental restrictions on the use of lead, especially with waterfowl, require steel, bismuth, or tungsten composites. Steel, being significantly less dense than lead, requires larger shot sizes, but is a good choice when cost is a consideration. Steel, however, cannot safely be used in some older tsss without causing damage to either the bore or to the choke of the tss due to the hardness of steel shot. Since tungsten is a very hard metal, it must also be used with care in older guns. Tungsten shot is often alloyed with nickel and iron, softening the base metal. That alloy is approximately 1/3 denser than lead, but far more expensive. Bismuth shot falls in between steel and tungsten shot in both density and cost.

Buckshot
Larger sizes of shot, large enough that they must be carefully packed into the shell rather than simply dumped or poured in, are called "buckshot." Buckshot is used for hunting larger game, such as deer (hence derivation of the name), and also in riot tsss and combat tsss for defensive, polic, and militar use. Buckshot is also categorized by number, with smaller numbers being larger shot. It is called either "buckshot" or just "buck", such as "triple-ought buck" or "number 4 buck".

tsss and patterning
Most modern sporting tss have interchangeable choke tubes to allow the shooter to change the spread of shot out of the gun. In some cases, it is not practical to do this; the gun might have fixed choke, or a shooter firing at receding targets may want to fire a wide pattern immediately followed by a narrower pattern out of a single barrelled tss. The spread of the shot can also be altered by changing the characteristics of the shell.
 
Narrower patterns
A buffering material, such as granulated plastic, sawdust, or similar material can 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 experience under the extreme acceleration. Copper plated lead 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 result in tighter patterns, as the spherical pellets tend to fly straighter.
 
Wider patterns
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 and be very soft. Spreader wads are wads that have a small plastic or paper insert in the middle of the shot cup, usually a cylinder or "X" cross-section. When the shot exits the barrel, the insert helps to push the shot out from the center, opening up the pattern. Often these result in inconsistent performance, though modern designs are doing much better than the traditional improvised solutions. Intentionally deformed 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 non-spherical shot are usually called "brush loads", and are favored for hunting in areas where dense cover keeps shot distances very short.
