Folder sleeves. Folder sleeve: ideal option
The tube material is specially developed multi-layer impregnated paper. Absolutely moisture and waterproof. The charge can neither become damp, nor fog up, etc. The material is very durable, does not crack or swell when fired. This is not a new product, but mass production for over 20 years. The number of shots fired from such cartridges runs into many millions. We did not find any negative reviews or obvious complaints throughout both the Russian and foreign segments of the Internet.
The height of the metal brass base is 12 mm. Sleeve length - 70 mm.Color- grey.
Capsule - CX-1000. The capsule socket is also suitable in diameter for a 209 Russian capsule.
The sleeve can easily withstand two or three reloads.
A paper sleeve has a main advantage over plastic ones - it can withstand almost any frost, down to minus 50 degrees, without losing its properties.
And plastic can be used to a limited extent even at temperatures above minus 20. At temperatures above 30 degrees below zero, it is better not to use it at all, no matter what manufacturers write about the frost resistance of plastic. In addition, most factory cartridges have plastic wad containers inside. For frost it is better to use cardboard pads and felt wads and wood-fiber ones.

Folder hunting cartridge consists of a paper tube rolled into several layers, one end of its barrel is open, and on the other there is a metal head firmly mounted with a flange, a bottom and a socket for the primer, which in most paper sleeves has the shape of a cylindrical hole, less often, like metal sleeves, it carries an anvil and seed holes. The metal head of the folder sleeve with the paper tube is pressed together using a paper wad, which is called the base wad of the sleeve.
An untwisted paper sleeve should be 0.5–1.0 mm shorter than the chamber, since when fired its tube is somewhat extended: a metal one is slightly shorter. If the cartridge case is longer than the chamber, then it enters the gun with difficulty; when fired on the slope from the chamber to the barrel bore, the wads are sharply compressed, the shot is deformed, the maximum pressure of the powder gases in the barrel bore increases sharply, the shooter feels a large recoil (push) in the shoulder, which leads not only to worsening of the battle, but also to swelling and even rupture of the barrel with all the ensuing consequences.
As for short sleeves, the opinions of researchers differ. Most believe that when firing from such a cartridge case, gases break through the wads and gaskets into the shot space and the ballistic qualities of the shot are significantly reduced. Along with this, there are indications that under the same conditions of loading cartridges with lengths of 65 and 70 mm, no difference in gas breakthrough could be detected, as well as differences in the speed of the projectile. This is explained by the fact that when fired, good wads and gaskets, being greatly deformed, create a reliable seal and, with the rapidity of the shot in a 5-mm area, do not allow gases to break through between the walls of the barrel and the surface of the wads.
Gun barrels are drilled for both paper and metal casings. The diameter of the barrel for a paper sleeve is slightly smaller than the diameter for a metal sleeve of the same caliber, since the walls of the metal sleeve are thinner than those of paper. Most modern 12, 16, and 20 gauge shotguns have barrels drilled for paper casing. In guns with such drilling, metal cartridges can also be used, but the accuracy and sharpness of the fire is reduced. When using paper cartridges in guns with barrels fitted with a metal sleeve, the combat is significantly worsened due to the breakthrough of powder gases into the shot.
The inner diameter of the sleeve should match the bore diameter as closely as possible. To check this, they make a cast of the middle part of the barrel and check the cartridges against it. If the cast does not fit into the muzzle of a new folder case, therefore, they cannot be used, the gun is made to look like metal.
The more accurately the channels of the cartridge case and the barrel match in size, the better the fight. A good match does not cause the shot shell and wads to realign as they move from the cartridge case to the barrel. In addition, a too wide channel of the (metal) cartridge case requires larger wads and leads to a sharp increase in gas pressure, which is not safe for the gun and the shooter.
Folder sleeves in modern guns, especially those produced domestically, they provide better combat due to the fact that the internal diameter of the paper sleeve better matches the diameter of the barrel bore. This sleeve is lighter, fits well to the walls of the chamber when fired, and makes it possible to use all types of primers and powders. It provides reliable fastening of a lightweight shot wad by rolling the barrel or sealing it with an “asterisk” when the shot wad is not placed at all. In addition, stable fastening of the projectile ensures high boost pressure, without which it is impossible to obtain a good quality shot. Boost pressure refers to the force of opening the case neck and overcoming the friction of wads, spacers and the projectile, expressed in kilograms per cross-sectional area of the case in square centimeters. To obtain high-quality combat, the boost pressure must be at least 40–50 kg/cm².
The folder sleeves produced by our industry require structural modification. First of all, they must be moisture resistant and not swell from dampness. There is no need to talk about the troubles swollen cartridges bring to the shooter when hunting, when you need to quickly reload the gun, and the cartridge, which has entered the chamber three-quarters of its length, does not go further and is not removed. Swelling of the cartridge case can cause especially big problems for automatic shotguns like M1D21-12. Therefore, many duck hunters prefer brass cartridges, putting up with the deterioration in the quality of the fight; others try to improve the shot by gluing several layers of paper inside metal cartridges so that the diameter of the cartridge bore matches the diameter of the barrel bore; and some are trying to use homemade methods to treat paper sleeves to protect them from moisture. To do this, use a slightly moistened woolen cloth to thoroughly wipe the outside with drying oil, allow to dry for 2-3 days and wipe again, and after 3-4 days they are equipped. You can increase the moisture resistance of paper sleeves by covering them with a thin layer of moisture-resistant varnish or BF-2 glue. You can also protect the folder sleeve from swelling by dipping the finished cartridge into molten paraffin or dipping it several times into a solution of film stripped from the emulsion in acetone or some other solvent. However, it is most effective to treat cartridge cases and finished paper cartridges with a paraffin-gasoline solution. Why take half a liter of aviation gasoline and dissolve 100 g of paraffin in it. To make the paraffin dissolve faster, it is crushed, and a container with gasoline is heated in hot water. Before impregnation, the solution is thoroughly mixed and cartridges or cartridges with a tightly closed barrel are thrown into it for 8-10 seconds. After this, they are placed in natural conditions for 10–12 hours of drying and calibrated. Fire safety measures are strictly observed during work.
Paper cartridges are produced as single-shot cartridges, designed for one shot, and multi-shot cartridges, designed for two or three shots. However, the strength of all paper sleeves produced by our factories is very low. With the first shot, up to 30–50% or more of completely new cartridges are destroyed. They burst in the longitudinal direction and cause burnouts in the area of the combustion chamber, which not only increases the cost of shooting, but also reduces the quality and stability of the shot. The transverse separation of the muzzle from the bottom is especially dangerous. In this case, the tube sometimes flies out of the barrel, and sometimes gets stuck in it, and if this is not noticed, then with the next shot the barrel will be swollen or torn.
Individual batches of paper sleeves vary greatly in strength and hardness. Because of this, they cannot provide the same conditions for opening the sealed cartridge case when fired. Therefore, under equal conditions of equipment and identical other elements of the cartridge, different boost pressures are obtained, and, consequently, different ballistic indicators of the shot.
12 gauge shells are the most common among hunters, so I decided to write an article about which are best used for hunting for 12-gauge shotguns, but the information in this article is directly relevant for other calibers of shotguns.
First, let's look at several types of hunting cartridges in more detail to understand their advantages and disadvantages.
12 gauge are familiar to all hunters, but now it is quite difficult to meet those hunters who use such cartridges in their arsenal. I shoot from them even in our modern times, but only in the summer-autumn period at birds.
You only need to use 10-gauge wads in such cases, and the gasket that rests on the shot should be filled with a solution of paraffin and rosin, which prevents the shot from falling out of the case.
Some hunters use ordinary Moment glue, which is poured in a small layer along the rim of the cartridge case, which also happens and holds the shot well in the cartridge case.
Special plastic plugs have already appeared on sale in stores, which are successfully used to retain shot in a metal sleeve.
Folder sleeves (paper) capricious because they have a number of disadvantages.
The material of such sleeves is fragile, they must be protected from moisture, constant ruptures. It is not recommended to shoot five rounds from such cartridges.
The rate of rupture of such cartridges can only be reduced if you carefully monitor the amount of gunpowder. The slightest overestimation leads to severe rupture of the sleeve.
If you pour Sokol gunpowder into paper cartridges, then more than 2.15 g simply cannot be used.
Sunar should not be used for such cases.
Plastic sleeves
12 gauge– this is an excellent material for equipping cartridges, but even in this case you should pay attention to some features.
When purchasing plastic sleeves, pay attention to the plastic material. She must be tough. Such cartridges hold the shot remarkably well.
The cartridge should be tightened to the “golden” mean. There is no need to over-tighten, but insufficient twist also results in a weak shot.
From all the observations and study of the practical application of various types 12 gauge shells a conclusion can be drawn that will create an overall picture of the rational and successful use of cartridges for smooth-bore weapons.
Conclusion: for shooting from horizontal, vertical and single-barreled shotguns, it is good to use metal and plastic cartridges, but for five-shot rifles, metal cartridges are contraindicated; plastic ones are best. Paper cartridges should be used in the absence of other types, but with caution and strict control of the powder weight.
A gun can fire well if the inner diameter of the cartridge case is close to the size of the bore. It is the thickness of the walls of the sleeve and its correspondence to the drilling of the chamber that provides maximum obturation and significantly affects the firing of the gun.
The internal diameter of the folder sleeve made in 1975, USSR is 18.1 + 0.2 mm, the brass sleeve is 19.5 mm.
The smaller diameter of the cardboard sleeve is obviously due to the thicker wall of the sleeve for its strength.
Most shotguns have a chamber drilled for paper and polyethylene cartridges. This is well known to many hunters, and the good old thick-walled, usually still Soviet or cardboard case Hubertus, GDR, best suited this rule - for most domestic and even older foreign hunting rifles, drilled for a folder sleeve, which still serve faithfully and truly in the caring hands of their owners.
A good-quality folder casing is usually not afraid of double reloading; sometimes it successfully withstands three or four times of use when shooting from strict chambers.
Previously, many decades ago, there were domestic folder cartridges on sale, the packaging of which proudly displayed the inscription “Multi-shot.” But usually such and even single-shot cartridges in the era of shortages were reloaded no more than three times. In any case, I personally, not having a large number of cardboard cartridges for my first, TOZ-BM 16-caliber, did just that.
It is believed that folder cartridges are good for shooting 12-gauge shotguns with a bore of 18.2 mm with a tolerance of + 0.2 mm. This was indeed the case on my father’s Izh-58 gun, with an internal barrel size of 18.3 mm, and the 18.4 mm bore of my MP-153 barrel also has a good fight on cartridges loaded with paper cartridges. But in such barrels with a bore diameter of 18.2-18.4 mm, the combat from the “brass” was already noticeably worse.
But Tula guns of previous years, like the TOZ-34 and the more modern TOZ-120, have an internal barrel size of 18.5 mm with a plus tolerance. Obviously, Tula gunsmiths took this step taking into account the use of brass cartridges by hunters.
At the same time, guns with a bore of 18.2 mm have stronger recoil than guns with a diameter of 18.4-18.5 mm, and this is clearly noticeable, especially when frequently shooting from two different guns alternately, for example, at a shooting range.
But with thoughtful, individual selection of a cartridge, neither a “narrow-bore” nor a wide bore will have noticeable advantages. Therefore, what kind of gun you have in your hands does not matter at all, the main thing is to try to find your cartridge for it. After all, you can achieve sharp action from any gun by individually selecting the components of the cartridge equipment: cartridge case, primer, gunpowder, seal, wad, shot.
Firing from empty chambers, extraction from pump-action and self-loading shotguns inevitably deforms the edge of the cartridge case bottom. All types of sleeves, without exception, are susceptible to this phenomenon.
The undoubted advantage of a cardboard sleeve is its “friendliness” towards nature. When shooting from self-loading rifles, in thick grass or thickets in a swamp, cartridges can be difficult to find and pick up. However, this is not a problem, nature will not suffer, and in two or three years they will disappear without a trace. They are also distinguished by the constancy of combat at different temperature conditions.
Cartridges equipped with folder sleeves are especially well suited for winter hunting, but only during the period when there is no high humidity and sharp fluctuations in daytime temperatures from minus to plus.
Otherwise, cartridges in paper sleeves that are not prepared for wet weather may become damp, which can result in an ineffective shot—“spitting.” And a long shot is even more dangerous for the hunter if the hasty shooter does not wait a few seconds and quickly tries to reload.
It happens that folder cartridges, repeatedly reloaded, tear along the seam in the “lax” chamber after a shot, but this is not so annoying. It is more unpleasant when an annular separation of the bottom of a worn-out cartridge case occurs. And then, if immediately inserting your finger tightly into the remaining tube in the chamber and turning it together, it was not possible to remove the detached part, then sometimes you have to contrive for a long time, using improvised means to get out the scraps of paper cartridge that were already deeply stuck in the barrel, and the double-barreled gun temporarily became a single-barreled gun .
You can use a homemade wire hook or cut a branch in the forest and make a rod out of it. For this case, our industry previously produced manual extractors of various calibers with an eccentric in the form of gears at one end and a calibration ring with an extractor at the other. A very convenient thing for such cases. This is exactly the extractor shown in the photo.
In the Soviet years, fans of self-loading shotguns MTs 21-12 preferred, due to various delays when shooting with folder cartridges, to shoot cartridges in plastic cartridges, which were in short supply at that time, especially on important driven hunts for ungulates. Probably, knowing the nature of their guns, they were right.
But I dare to note that already with the advent of gas-operated semi-automatic devices, the use of cartridges loaded with new cardboard sleeves became quite possible. In any case, many times I shot from the MP-153 gun with cartridges in paper cartridges with any full-weight charges - there were never delays due to the tearing off of the bottom of these cartridges.
Modern folder cartridges with standard weights of gunpowder, shot, with polyethylene PC, VP or fiberboard withstood a maximum of two reloads in the same chamber of my gun and then tore longitudinally, but thick-walled paper cartridges of old, Soviet stocks with identical loading methods without loss of quality The shot was fired more than three times without any rupture of the tube at all.
Moreover, such sleeves were used with both high and low bottom bases. Various years of production, with and without a “duck”, including those that were stored for many decades on the mezzanine and one day came to me...
Perhaps I was lucky, or this is really a feature of the MP-153 shotgun model, my omnivorous copy of a gas-operated semi-automatic machine, but I would still be careful when shooting from shotguns with a recoil barrel like the MTs-21-12 with cartridges with folder casings.
In part, a paper casing is more convenient and safer for shooting from shotguns, where any shooter should make it a rule after each shot, regardless of the casing used, to blow out the barrels, holding them up to the light, thereby protecting himself from unforeseen accidents, like a wad stuck in the middle barrel or a flying paper bottom from a metal base-base of a folder or polyethylene sleeve, weakened by many reloads. And this is fraught with rupture of the barrel and loss of health of the shooter.
A significant disadvantage of folder sleeves is their low moisture resistance unless they are additionally treated with a special compound. Having swollen from moisture, they can no longer be inserted into the chamber.
When hunting in high humidity, it would be wise to fill your bandoleer with cartridges chambered in plastic casings or brass, if the design of the gun allows it.
...Decades have passed, but even today, with a sufficient selection of cartridges from various companies and an abundance of plastic casings (from the stand), the hunter’s soul again and again reaches out to products from the past - the good old folder casing.
But why is this happening? After all, a folder casing is neither better nor worse, you just need to know how to load the cartridges correctly, and so, with the selection of components and careful equipment, there will not be much difference in the firing of the gun between a cartridge in a thick-walled plastic and a folder casing.
However, a fight is a fight, but a folder sleeve is, first of all, a tribute to time, hunting traditions, a memory of the glorious past, spiritual memories of bygone days, when one day, for the first time, as a boy, I went hunting; nostalgia for our hunting youth and for our untimely departed relatives and people close to us.
Today, leisurely shooting with cartridges loaded in folder casings is more the lot of an esthete with a double-barreled shotgun. Such a spent gourmet cartridge always remains with a pleasant smell, like the fragrant aroma of excellent coffee brewed in the morning, in contrast to a public catering draft drink.
It’s a pity that the domestic manufacturer has already stopped producing paper cartridges, but among hunters there are people whose hunting path began in childhood, when, as still small children, with bated breath, they carefully watched with their children’s eyes how hunting cartridges were loaded with strong the hands of a father, or perhaps a grandfather, who looked at them with undisguised love, future equally passionate hunters, using an ordinary Barclay, a pharmacy scale on a harsh thread, a measure and a hand twist. And for them, refusing to roll a cigarette in a folder sleeve is akin to breaking with their family. And whoever does not remember his past has no future.
