Definitions
- the reduced capacity allows for a more efficient ignition of the powder and a higher load density with less powder.
- Low load density (roughly below 30-40%) is one of the main contributors to the Secondary Explosive Effect (SEE).
- SEE can destroy the strongest rifle action and it can happen on the first shot or the tenth.
- SEE is the result of slow or incomplete ignition of small amounts of smokeless powder.
- the powder smolders and releases explosive gases which, when finally ignited, detonate in a high order explosion.
- the better sealing effect is also important here because standard brass does not seal the chamber well at the lower pressures created during subsonic shooting.

Description
- The present subject matter relates to techniques and equipment to make ammunition articles and, more particularly, to ammunition articles with plastic components such as cartridge casing bodies and bases for at least blank and subsonic ammunition.
- It is well known in the industry to manufacture bullets and corresponding cartridge cases from either brass or steel. Typically, industry design calls for materials that are strong enough to withstand extreme operating pressures and which can be formed into a cartridge case to hold the bullet, while simultaneously resist rupturing during the firing process.
- Conventional ammunition typically includes four basic components, that is, the bullet, the cartridge case holding the bullet therein, a propellant used to push the bullet down the barrel at predetermined velocities, and a primer, which provides the spark needed to ignite the powder which sets the bullet in motion down the barrel.
- The cartridge case is typically formed from brass and is configured to hold the bullet therein to create a predetermined resistance, which is known in the industry as bullet pull. The cartridge case is also designed to contain the propellant media as well as the primer.
- However, brass is heavy, expensive, and potentially hazardous. For example, the weight of 0.50 caliber ammunition is about 60 pounds per box (200 cartridges plus links).
- The bullet is configured to fit within an open end or mouth of the cartridge case and conventionally includes a groove (hereinafter referred to as a cannelure) formed in the mid section of the bullet to accept a crimping action imparted to the metallic cartridge case therein. When the crimped portion of the cartridge case holds the bullet by locking into the cannelure, a bullet pull value is provided representing a predetermined tension at which the cartridge case holds the bullet. The bullet pull value, in effect, assists imparting a regulated pressure and velocity to the bullet when the bullet leaves the cartridge case and travels down the barrel of a gun.
- Furthermore, the bullet is typically manufactured from a soft material, such as, for example only, lead, wherein the bullet accepts the mouth of the cartridge being crimped to any portion of the bullet to hold the bullet in place in the cartridge case, even though the cartridge case is crimped to the cannelure of the bullet.
- However, one drawback of this design is that the crimped neck does not release from around the bullet evenly when fired. This leads to uncertain performance from round to round. Pressures can build up unevenly and alter the accuracy of the bullet.
- The propellant is typically a solid chemical compound in powder form commonly referred to as smokeless powder. Propellants are selected such that when confined within the cartridge case, the propellant burns at a known and predictably rapid rate to produce the desired expanding gases. As discussed above, the expanding gases of the propellant provide the energy force that launches the bullet from the grasp of the cartridge case and propels the bullet down the barrel of the gun at a known and relatively high velocity.
- The primer is the smallest of the four basic components used to form conventional ammunition. As discussed above, primers provide the spark needed to ignite the powder that sets the bullet in motion down the barrel. The primer includes a relatively small metal cup containing a priming mixture, foil paper, and relatively small metal post, commonly referred to as an anvil.
- When a firing pin of a gun or firearm strikes a casing of the primer, the anvil is crushed to ignite the priming mixture contained in the metal cup of the primer. Typically, the primer mixture is an explosive lead styphnate blended with non-corrosive fuels and oxidizers which burns through a flash hole formed in the rear area of the cartridge case and ignites the propellant stored in the cartridge case. In addition to igniting the propellant, the primer produces an initial pressure to support the burning propellant and seals the rear of the cartridge case to prevent high-pressure gases from escaping rearward. It should be noted that it is well known in the industry to manufacture primers in several different sizes and from different mixtures, each of which affects ignition differently.
- The cartridge case, which is typically metallic, acts as a payload delivery vessel and can have several body shapes and head configurations, depending on the caliber of the ammunition. Despite the different body shapes and head configurations, all cartridge cases have a feature used to guide the cartridge case, with a bullet held therein, into the chamber of the gun or firearm.
- The primary objective of the cartridge case is to hold the bullet, primer, and propellant therein until the gun is fired. Upon firing of the gun, the cartridge case seals the chamber to prevent the hot gases from escaping the chamber in a rearward direction and harming the shooter. The empty cartridge case is extracted manually or with the assistance of gas or recoil from the chamber once the gun is fired.
- As shown in
FIG. 1A , abottleneck cartridge case 10 has abody 11 formed with a shoulder 12 that tapers into a neck 13 having a mouth at a first end. Aprimer holding chamber 15 is formed at a second end of the body opposite the first end. Adivider 16 separates a main cartridgecase holding chamber 17, which contains a propellant, from theprimer holding chamber 15, which communicate with each other via a flash hole channel 18 formed in theweb area 16. An exterior circumferential region of the rear end of the cartridge case includes anextraction groove 19a and arim 19b. - Prior art patents in this area include
U.S. Patent No. 4,147,107 to Ringdal ,U.S. Patent No. 6,845,716 to Husseini et al. ,U.S. Patent No. 7,213,519 to Wiley et al. , andU.S. Patent No. 7,610,858 to Chung . The four patents are directed to an ammunition cartridge suitable for rifles or guns and including a cartridge case made of at least a plastics material. However, each have their own drawbacks. - Further, the use of brass cartridges for blank or subsonic ammunition can be problematic. To reduce the velocity of the bullet exiting the cartridge, typically less propellant is used is comparison to when the bullet is traveling at its top velocity. However, the same size cartridge needs to be used so the bullet can be fired from a standard firearm. An empty space is left inside a blank or subsonic cartridge where the propellant would normally reside. To compensate, wadding (typically cotton) can be packed into the space normally filled by the propellant. This wadding can cause problems with the use of the round, including jamming the firearm and fouling silencers and/or suppressors attached to the firearm.
- Hence, a need exists for a polymer casing that can perform as well as or better than the brass alternative. A further improvement are polymer casings that are capable of production in a more conventional and cost effective manner, i.e. by using standard loading presses. Additionally, the cartridge can provide increased performance for blank and subsonic rounds.
- The teachings herein alleviate one or more of the above noted problems with the strength and formation of polymer based cartridges.
- Thus, a high strength polymer-based cartridge casing can include an upper component, molded from a polymer, and having a first end with a mouth, at least a wall between the first end and a second end of the upper component opposite the first end, a sleeve extending longitudinally and radially about the wall, and at least one of an overlap portion and an underskirt portion extending from the wall near the second end. The lower component is molded from a polymer and includes at least one of a tapered portion and an outer tapered portion that engages at least one of the overlap portion and the underskirt portions, respectively, to join the upper and the lower components. Further, the sleeve reduces a volume of a propellant chamber formed by the wall. The reduced volume of the propellant chamber permits only enough propellant to propel a bullet engaged in the cartridge casing at subsonic speeds or less, if it is a blank cartridge.
- Alternately, the upper component of the high strength polymer-based cartridge casing can further include an extension engaged at the mouth and a cap engaged to an end of the extension opposite the mouth. In an example, the cap elastically deforms when the cartridge is fired.
- As a result, a light weight, high strength cartridge case can be formed using standard brass cartridge loading equipment. As noted below, the present invention can be adapted to any type of cartridge, caliber, powder load, or primer. Calibers can range at least between .22 and 30 mm and accept any type of bullet that can be loaded in a typical brass cartridge.
- Further advantages can be gained in both blank and subsonic ammunition due to the removal of wadding and the shrinking of the volume of powder based on a reduced volume in the cartridge.
- The polymer used can be of any known polymer and additives, but the present invention uses a nylon polymer with glass fibers. Further, the portion of the cartridge that engages the extractor of the firearm can be made from heat strengthened steel for normal loads and can be a continuous molded polymer piece of the lower component for either subsonic or blank ammunition.
- Additional advantages and novel features will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following and the accompanying drawings or may be learned by production or operation of the examples. The advantages of the present teachings may be realized and attained by practice or use of various aspects of the methodologies, instrumentalities and combinations set forth in the detailed examples discussed below.
- The drawing figures depict one or more implementations in accord with the present teachings, by way of example only, not by way of limitation. In the figures, like reference numerals refer to the same or similar elements.

However, it should be apparent to those skilled in the art that the present teachings may be practiced without such details. In other instances, well known methods, procedures, components, and/or circuitry have been described at a relatively high-level, without detail, in order to avoid unnecessarily obscuring aspects of the present teachings.
- The present invention provides a cartridge case body strong enough to withstand gas pressures that equal or surpass the strength of brass cartridge cases under certain conditions, e.g. for both storage and handling.
- Reference now is made in detail to the examples illustrated in the accompanying drawings and discussed below.
FIG. 2 illustrates an example of acartridge case 100. Thecartridge case 100 includes anupper component 200, alower component 300, and aninsert 400. In this example, theupper component 200 and thelower component 300 are made of a polymer, whileinsert 400 is made from a metal, an alloy of metals, or an alloy of a metal and a non-metal. Regardless of materials, the outer dimensions of thecartridge case 100 are within the acceptable tolerances for whatever caliber firearm it will be loaded into. - The polymer used is lighter than brass. A glass-filled high impact polymer can be used where the glass content is between 0%-50%, preferably between 5% and 50%. In another example the glass content can be 10%. An example of a high impact polymer without the glass content is BASF's CapronĀ® BU50I. The
insert 400 can be made of steel, and, in an example, heat treated carbon steel, 4140. The 4140 steel is further heat treated to a Rockwell "C" scale ("RC") hardness of about 20 to about 50. However, any carbon steel with similar properties, other metals, metal alloys or metal/non-metal alloys can be used to form the insert. Heat treating a lower cost steel alloy to improve its strength is a point of distinction from the prior art, which have typically opted for more expensive alloys to deal with the strength and ductility needed for a cartridge casing application. - In an example, the combination of the
upper component 200 and thelower component 300 are made of 10% glass-filled high impact polymer combined with theinsert 400 made of heat treated 4140 steel results in a cartridge that is approximately 50% lighter than a brass formed counterpart. This weight savings in the unloaded cartridge produces a loaded cartridge of between 25%-30% lighter than the loaded brass cartridge depending on the load used, i.e. which bullet, how much powder, and type of powder used. - The
upper component 200 includes abody 202 which transitions into ashoulder 204 that tapers into aneck 206 having amouth 208 at afirst end 210. Theupper component 200 joins thelower component 300 at an opposite,second end 212. Thelower component 300 joins theupper component 200 at a lower component first end 302 (seeFIG. 6 ). The upper 200 and lower 300 components are adhered by an ultraviolet (UV) light or heat cured resin, a spin weld, a laser weld or an ultrasonic weld. - At a
second end 304 of thelower component 300, the lower component is joined to theinsert 400. In one example, theupper component 200 and thelower component 300 are molded in separate molds. When thelower component 300 is molded, it is molded over theinsert 400. This is a partial molding over, since thelower component 300 does not completely cover theinsert 400. - A
back end 402 of theinsert 400 is also the rear end of thecasing 100. Theinsert 400 is formed with anextraction groove 404 and arim 406. Thegroove 404 andrim 406 are dimensioned to the specific size as dictated by the caliber of the ammunition. Theinsert 400 can be formed by turning down bar stock to the specific dimensions or can be cold formed. - Turning now to
FIG. 3 , a cross-section of theupper component 200 is illustrated. Because of the nature of the polymer, and the design of theneck 206 andmouth 208, theneck 206 expands uniformly under the gas pressures formed during firing. This concentric expansion provides a smoother release of the projectile into the barrel of the firearm. The smoother release allows for a more stable flight of the projectile, providing greater accuracy and distance with the same amount of powder. - Moving toward the
second end 212 of theupper component 200, as theneck 206 transitions into theshoulder 204, asleeve 230 begins. Thesleeve 230, in this example, extends approximately to thesecond end 212. Thesleeve 230 can be an additional thickness to awall 218 as is normally required for a standard cartridge, or a separately manufactured and adhered to thewall 218. Thesleeve 230 provides additional strength relative to thewall 218 of thebody 202 alone. This strengthening, which is in the lateral direction, reduces bending of theupper component 200 of thecartridge case 100. Thesleeve 230 helps to keep thecartridge 100 as concentric as possible, and as noted above, concentricity is a key to accuracy. - The
case wall 218 can have a thickness T, and thesleeve 230 can have a thickness T+, as illustrated inFIG. 4 . Thus, the total thickness of the cartridge at the point where there is thewall 218 andsleeve 230 is the sum of T and T+. - The
upper portion 220 of thesleeve 230 can begin in or near theneck 206 and extend over theshoulder 204. In one example, theupper portion 220 of thesleeve 230 ends against a bullet 50 (seeFIG. 1 B) providing additional material, and thus strength, to help retain and align thebullet 50. This thickenedupper portion 220 can act like an extension of theneck 206 farther down into the shoulder. Theupper portion 220 is an advantage over a brass cartridge, since brass cannot be formed in this way. Thus, theupper portion 220 can act to sit and secure the bullet in the same place in the cartridge every time. - The
sleeve 230, in the illustrated example ofFIGs. 3 ,4 and 5 , extends almost the entire length of thebody 202. Thesleeve 230 stops at anoverlap potion 222 of theupper component 200. Theoverlap portion 222 is the portion of theupper component 200 that engages thelower component 300. Theoverlap portion 222 has a thinner wall thickness t, or a second thickness, at thesecond end 212 than the thickness T of the wall 218 (or T and T+) before theoverlap portion 222. The second thickness t tapers toward the outside of theupper component 200 so an outer diameter 224 of thewall 218 remains constant while aninner diameter 226 of thewall 218 increases. This allows certain examples ofcartridge 100 to maintain a constant outer diameter from below theshoulder 204 to theinsert 400. Thebottom end 228 of thesleeve 230 is approximately squared off to provide a square shoulder to keep the upper 200 and lower 300 components concentric during assembly. -
FIGs. 6-8 illustrate that thelower component 300 has a taperedportion 306 starting at the lower componentfirst end 302 and ending at acollar 308. The slope of the taperedportion 306 approximately matches the slope of theoverlap portion 222 so the two can slide over each other to engage the upper 200 and lower 300 components. The taperedportion 306 ends in aflat seat 307. Theseat 307 can have a thickness Ts which is about equal to the thickness of the wall and/or sleeve. This allows thebottom end 228 of the sleeve to sit on theseat 307 when the upper 200 and lower 300 components engage. This prevents thebottom end 228 of thesleeve 230 from being exposed. This could allow the gases to exert pressure on thebottom end 228 that can separate the upper 200 from the lower 300 component. - A width of the
collar 308 matches the second thickness t, so that the outer diameter of thecartridge 100 remains constant past the transition point between the upper 200 and lower 300 components. Further, a thickness of the taperedportion 306 is such that at any point the sum of it with the thickness of theoverlap portion 222 is approximately equal to the thickness T of thewall 218 or the thicknesses of thewall 218 and sleeve 230 (T and T+). As noted above, the taperedportion 306 and theoverlap portion 222 are bonded together to join the upper 200 and lower 300 components. - An
inner wall 310 of thelower component 300 can be formed straight. In the illustrated example inFIG. 8 , theinner wall 310 forms a bowl shape with ahole 312 at the bottom. Thehole 312 is formed as a function of the interface between thelower component 300 and theinsert 400, and its formation is discussed below. As theinner wall 310 slopes inward to form the bowl shape, it forks and forms aninner bowl 314 and anouter sheath 316. Thegap 318 that is formed between theinner bowl 314 and theouter sheath 316 is the space where a portion of theinsert 400 engages thelower component 300. As noted above, in one example, thelower component 300 is molded over a portion of theinsert 400 to join the two parts. - Turning now to an example of the
insert 400, as illustrated inFIG. 9 , it includes anovermolded area 408, where theouter sheath 316 engages theinsert 400 in thegap 318. Theovermolded area 408 has one ormore ridges 410. Theridges 410 allow the polymer from theouter sheath 316, during molding, to forms bands 320 (see,FIG. 8 ) in thegap 318. The combination of theridges 410 andbands 320 aid in resisting separation between theinsert 400 and thelower component 300. The resistance is most important during the extraction of the cartridge from the firearm by an extractor (not illustrated). - The
overmolded area 408 also includes one ormore keys 412. Thekeys 412 are flat surfaces on theridges 410. Thesekeys 412 prevent theinsert 400 and thelower portion 300 from rotating in relation to one another, i.e. theinsert 400 twisting around in thelower portion 300. - Below the
overmolded area 408, toward theback end 402, is a self reinforcedarea 414. This portion extends to theback end 402 of theinsert 400 and includes theextraction groove 404 andrim 406. The self reinforcedarea 414 must, solely by the strength of its materials, withstand the forces exerted by the pressures generated by the gasses when firing the bullet and the forces generated by the extractor. In the present example, the self reinforcedarea 414 withstands these forces because it is made of a heat treated metal or a metal/non-metal alloy. -
FIGs. 10 and 11 illustrate an example of the inside of theinsert 400. Open along a portion of theback end 402 and continuing partially toward theovermolded area 408 is aprimer pocket 416. Theprimer pocket 416 is dimensioned according to the standards for caliber of the cartridge case and intended use. A primer (not illustrated) is seated in theprimer pocket 416, and, as described above, when stricken causes an explosive force that ignites the powder (not illustrated) present in the upper 200 and lower 300 components. - Forward of the
primer pocket 416 is aflash hole 418. Again, theflash hole 418 is dimensioned according to the standards for the caliber of the cartridge case and intended use. Theflash hole 418 allows the explosive force of the primer, seated in theprimer pocket 418, to communicate with the upper 200 and lower 300 components. - Forward of the
primer pocket 416 and inside theovermolded area 408 isbasin 420. Thebasin 420 is adjacent to and outside of theinner bowl 314 of thelower component 300. Thebasin 420 is bowl shaped, wherein the walls curve inwards toward the bottom. The bottom of thebasin 420 is interrupted by aring 422. Thering 422 surrounds theflash hole 418 and extends into thebasin 420. It is the presence of thering 422 that forms thehole 312 in theinner bowl 314 of thelower component 300. - In another example of a cartridge case 120, the sizes of the upper 200 and lower 300 components can be altered.
FIG. 12 illustrates a "small upper" embodiment with abullet 50 in themouth 208 of the cartridge 120. The features of the upper 200 and lower 300 component are almost identical to the example discussed above, and theinsert 400 can be identical.FIG. 12 also illustrates the engagement between alip 214 and thecannelure 55. Thelip 214 is a section of theneck 206 approximate to themouth 208 that has a thicker cross section or, said differently, a portion having a smaller inner diameter than the remainder of theneck 206. In this example, thelip 214 is square or rectangular shaped, no angles or curves in the longitudinal direction. Note, in other examples, theupper component 200 is not formed with alip 214. When present, thelip 214 engages thecannelure 55 formed along an outer circumferential surface of thebullet 50 when it is fitted into themouth 208 of thecartridge casing 100. -
FIG. 13 shows that theneck 206 and theshoulder 204 are formed similar, but in this example, thebody 202 is much shorter. Further, instead of anoverlap portion 222, there is anunderskirt portion 240 that starts very close to theshoulder 204. Theunderskirt portion 240 tapers to the inside of the cartridge when it engages thelower component 300. - The
lower component 300 in this further example, is now much longer and comprises most of thepropellant chamber 340. The tapered portion is now replaced with an outertapered portion 342. The outer taperedportion 342 slides over theunderskirt portion 240 so the two can be joined together as noted above. The thickness of theunderskirt portion 240 and the outer taperedportion 342 is approximate to the wall thickness or wall thickness and sleeve thickness. - The
inner wall 310 is now substantially longer, can include a sleeve, but still ends in theinner bowl 314. The engagement between thesecond end 304 of thelower component 300 and theinsert 400 remains the same. Note that either the "small upper" or "long upper" can be used to form blank or subsonic ammunition. The walls are made thicker with the sleeve, shrinking the size of thepropellant chamber 340. Less powder can be used, but the powder is packed similarly as tight as it is for a live round because of thesmaller chamber 340. This can prevent the Secondary Explosive Effect (SEE) (below). A thick wall design for asubsonic cartridge 140 is illustrated inFIG. 14 . - Illustrated is a large
upper component 200 having athicker overlap 222 portion, with a thickness t+ and an integral thickening of the wall, and/or asleeve 230 with a thickness T+, as disclosed above. The total thickness of thewall 218 can be the sum of T+ and t+. Thesleeve 230 can run the length of theupper component 200 from themouth 208 to the start of theoverlap portion 222. Thelower component 300 of asubsonic cartridge 140 can be thickened as well. Thesubsonic cartridge 140 can be made with theinsert 400, or thelower component 300 can be molded in one piece from polymer with the features of theinsert 400. For example, theflash hole 418,primer pocket 416,groove 404 andrim 406. Alternately, the insert can also be high-strength polymer instead of the metal alloys discussed above. In this example, the lower component and the insert can be formed as one piece, and theupper component 200 can be placed on top. - As illustrated in
FIG. 15 , for ablank cartridge 150, theupper component 200 can be made differently. For theblank cartridge 150, anextension 242 can be molded to extend from theneck 206. Theextension 242 has a star-shapedcap 244 to seal off the cartridge. Thecap 244 is formed partially of radially spacedfingers 246 that deform outwards during firing. Thus, themouth 208 is molded partially shut to contain a majority of the pressures and expand open and outwards. Thefingers 246 are designed, in one example, to be bend elastically and are not frangible. The object is to contain the majority of the pressures and expel anything that can act as a projectile out the barrel of the firearm. - When the
blank cartridge 150 is formed with the "small upper"component 200 with thecap 244. Thelower component 300 can be filled with the powder and the small upper component can act as a cap to the cartridge, sealing in the powder. - Note that the above examples illustrate a bottleneck cartridge. Many of the features above can be used with any cartridge style, including straight wall cartridges used in pistols.
FIG. 16 illustrates an example of astraight wall cartridge 500. Thestraight wall cartridge 500 is a one-piece design of all polymer. Thecartridge 500 has abody 502 and amouth 508 at afirst end 510. Thewalls 518 of the cartridge casing can also have a sleeve 530 along a majority of its length. - The
sleeve 230, 530 is dimensioned and shaped pursuant to the requirements of each cartridge based on blank or subsonic and the particular caliber. To that end, the sleeve 530 begins set back from thefirst end 510 based on the depth the rear of the bullet sits in the cartridge. Further, in this example, as the walls transition into alower bowl 514, the sleeve 530 may extend into the bowl. This aids in the strength of aback end 512 of thecartridge 500, since this example lacks a hardened metal insert. - The
lower bowl 514 curves downward toward aflash hole 517 which then opens to aprimer pocket 519. Both are similar to the features described above. Further, the back end is molded to form arim 506. - Turning now to an example of a fully formed
cartridge case 100,FIG. 17 illustrates a cross-section of all three elements engaged together to illustrate how they interface with each other. The specific outer dimensions of the three elements and certain inner dimensions (e.g. mouth 208,lip 214,flash hole 418, and primer pocket 416) are dictated by the caliber and type of the firearm and type of ammunition. Thecartridge casing 100 of the present invention is designed to be used for any and all types of firearms and calibers, including pistols, rifles, manual, semi-automatic, and automatic firearms. - An exemplary construction of the
upper component 200 also aids in withstanding the pressures generated. As noted above, thesleeve 230 increases the strength of thewall 218 of theupper component 200. In the present example, theupper component 200 accounts for anywhere from 70% to 90% of the length of thecartridge casing 100. - The polymer construction of the cartridge case also provides a feature of reduced friction between the cartridge and chamber of the firearm. Reduced friction leads to reduced wear on the chamber, further extending its service life.
- Subsonic ammunition can be manufactured using the above illustrated examples. Subsonic ammunition is designed to keep the bullet from breaking the speed of sound (approximately 340 m/s at sea level or less than 1,100 fps). Breaking the speed of sound results in the loud "crack" of a sonic boom, thus subsonic ammunition is much quieter than is standard counterpart. Typical subsonic ammunition uses less powder, to produce less energy, in the same cartridge case as standard ammunition. The remaining space is packed with wadding/filler to keep the powder near the flash hole so it can be ignited by the primer. As noted above, increasing the wall thickness eliminates the need for wadding. In one example, while a brass cartridge wall can be 0.0389" thick, the polymer wall and sleeve can have a total thickness of 0.0879" for the identical caliber.
- The reduced capacity allows for a more efficient ignition of the powder and a higher load density with less powder. Low load density (roughly below 30-40%) is one of the main contributors to the Secondary Explosive Effect (SEE). SEE can destroy the strongest rifle action and it can happen on the first shot or the tenth. SEE is the result of slow or incomplete ignition of small amounts of smokeless powder. The powder smolders and releases explosive gases which, when finally ignited, detonate in a high order explosion. The better sealing effect is also important here because standard brass does not seal the chamber well at the lower pressures created during subsonic shooting.
