A firearm damage is a firearm failure to operate as intended for causes other than user error. Damage works from a temporary and relatively secure situation, such as an unexpurgated casing, to potentially harmful events that can damage a rifle permanently and cause injury or death. Handling certain types of malfunctions that are not true can be very dangerous. The basic rules of firearm safety should be followed at all times to minimize the risk of shooters and observers. Proper cleansing and maintenance of firearms play a major role in preventing malfunctions.

Cartridge damage
Case head case
Separation of case head occurs when the casing wall becomes thin or tired. After firing on the round, the casing is divided into two parts near the head. Not infrequently with brass that has been reloaded several times.
Dud
A dud (also misfire or failure to fire) occurs when the trigger is withdrawn but the primer or powder in the cartridge malfunctions, causing the firearm not to be disposed of. Dud rotation can still be dangerous and must be disabled and disposed of properly.
Flame hanging
The burned fire (also delayed discharge) is an unexpected delay between triggering firearms and propellant ignition. Whenever a firearm fails to fire, but it is not obviously not working, a hanging shot should be suspected. When this happens, the correct procedure is to keep the firearm down or in a safe direction for thirty to sixty seconds, then release and release it securely round (which is now useless as described above if the primer is struck, if no, the gun itself may not work). The reason for this is that a rotation that works outside a firearm, or in a firearm with an open action (running out of battery), can cause serious fragmentation hazards.
Squib loading
The squib load (also squib round, squib, squib fire, insufficient discharge, incomplete discharge) is a very dangerous damage that occurs when a fired projectile does not carry enough strength and gets stuck in the gun barrel rather than getting out of it. In the case of semi-automatic or automatic weapons, this may cause subsequent rounds to affect projectiles blocking the barrel, which may lead to catastrophic failure of the structural integrity of firearms, posing a threat to operators or observers. The bullet from a squib trapped in a barrel should not be cleaned by then trying to fire a live or empty spin into an unobstructed barrel. The empty loop uses a different type of powder than the other, and produces more pressure, combined with the presence of a projectile that blocks the barrel can cause the firearm to fail simultaneously.

Mechanical damage
Errors in mechanical functioning of firearms (usually called jams) include failure to feed, extract, or remove cartridges; failure to fully cycle after shooting; and the failure of firearms operated or re-operated to lock back when empty (mostly procedural danger, as "sliding lock" is a visual cue that firearms are empty). In extreme cases, excessively disassembled bullets, blocked barrels, poor design and/or a very weak breech can cause explosive failure of the receiver, barrel, or other part of the firearm.
Failed to feed
Failure to Feed (FTF) is when a firearm fails to feed the next round into the firing room. Failure to feed is common when the shooter does not hold a firearm firmly (known as a limp wrist), when the slides are not fully moved by the previous round, or because of problems with the magazine.
Hammer follow
Hammer follow occurs when the disconnector allows the hammer to follow the bolt and shoot the pin to the battery, sometimes causing the burning mechanism to function without pulling the trigger. This is usually the result of extreme wear or direct damage to the ignition mechanism components, and may result in uncontrollable "full-auto" operations, in which multiple turns are released after a trigger pull.
Slamfire
Slamfire is the unintentional and accidental release of firearms that occur when a round is being loaded into the chamber, when the bolt "slams" forward (hence its name), as a result of firing the pin that has not been drawn into the bolt. , or from the firing pin brought forward by momentum back to the battery. Similar to malfunctioning hammer, this can lead to uncontrolled "full-auto" operation.
Failure to extract
Failure to extract occurs when the casing of the round just fired is not successfully extracted from the room. This can be caused by rooms that are too dirty, broken extractor paws, box edge failures, or some other cause.
Failed to release
Failure to issue (FTE) occurs when the casing of the fired round is extracted from the chamber, but not removed from the firearm, causing the next round to fail to feed, or the slide/bolt fails to return to the battery. Chimneys are a common type of FTE.
Stovepipe
Chimneys or chimneys typically occur in the action of pumps, semi-automatic, and fully automatic firearms fired from closed bolts, when empty cartridge boxes are caught out of the throwing ports rather than thrown clearly. Stovepipes can be caused by a malfunctioning or damaged extractor or ejector, or when the shooter does not hold a firearm strong enough for a fully functioning action, known as a weak ankle, or because of a relentless reinstallation to fully cycle the action, etc..
Double feed (Type 3 inability)
Double feed occurs when the rounds are out in the room and the slide takes a second round of magazines mashing it into the first. This can be caused by a damaged extractor or a damaged casing left in the room, and for cleaning can require a simple tool.
Battery depleted
Firearms are "batteries" when slides/bolts are in the normal firing position. The firearm is "running out of battery" when the slide/bolt/action is not fully seated in the normal firing position, usually because it does not rotate completely after firing (called "back to battery"). The most modern firearms are designed to not be able to shoot when significantly run out of batteries. Thus, firearms that do not have batteries usually can not be fired, which is why this is a type of firearm damage.
A hazardous situation can occur when round a fire chamber when a firearm runs out of battery (called out-battery-discharge). The cartridge case is not strong enough to withstand firing pressure by itself; it depends on the space wall and bolt face to help withstand the pressure. When the firearm runs out of battery, the rotation is not fully chambered, or the face of the bolt is not against the back of the cartridge, and if the round is fired in this situation, the casing will fail, causing high-pressure hot gas, a little powder burn, and the pieces of the casing itself thrown with high speed of firearms. This can be a serious danger for firearms operators, and every observer.
Prevention
Some mechanical malfunctions are caused by poor design and can not be easily avoided. Some malfunctions with cartridges may be associated with poor quality or broken ammunition (often due to improper storage, moisture exposure). Many malfunctions, however, can be prevented by proper cleaning and maintenance of firearms.
