==Ammunition themselves== 
To call a round or cartridge "a bullet" would be the equivalent of calling of calling a magazine a clip. Bullets are the projectiles that are or to be launched, while the "round" is the entire thing. To do otherwise would summon the wrath of the /k/ommando.

===Composition of the modern round/cartridge===

*Casing - The metal jacket that houses the propellant, primer, and to an extent the bullet (pardoning telescopic munitions which house the bullet completely.) Usually made from brass, they can be made from steel or plastics (at the detriment of the gun itself, unless designed for such).

*Propellant - Powder that is used to propel the bullet/slug/projectile. In the good ol' days, it used black powder (which was made from charcoal, sulphur, and saltpeter - either potassium nitrate or sodium nitrate), but those clouded the air with black smoke, left soot in the gun, were corrosive, and weren't powerful. Most modern rounds use a double base powder (generally guncotton/nitrocellulose, both dry and in a dissolved form called collodion, and nitroglycerin), may include a variety of stabilizers (to improve shelf life of the round) and deterrents (to prevent the cartridge from being too "hot" and prematurely combusting or shattering the barrel from overpressure). Historically, the British formed their propellant as stiff string called Cordite stuffed into cartridges before the mainstream use of small grains took over. For artillery, they make good use of triple base propellants, which is smokey as hell but burn well with no corrosive fouling.

*Primer - What activates the powder in the rounds themselves. Replacing the finnicky and hydrophobic matchlock, wheellock, and flintlock, they're percussion caps filled with sensitive explosive compounds (like picrates, fulminates, perchlorates, styphnates, tetrazenes, or azides) that ignite upon being hit. Generally a firm dent is enough to activate the munitions. Modern commercial ammo generally use non-corrosive compression sensitive materials, though many governments kept using corrosive primers well into the Cold War due to surplus stock and cost reduction.

*Bullets - What people get tripped up on in naming munitions. Being the projectile, anyone loading the munitions has a vast choice of what can be used as a bullet. Generally, lead, steel, and tungsten make the core of the round (thanks to their weight) while the outer coat for the round could be lead (since it is also very malleable), copper, and nickel, though Teflon and certain plastics can also be used. If you're feeling lucky, you can load a variety of other materials into the rounds (or shells for shotguns). Take for example salt, which doesn't kill, but you can mark people and they sting like hell. Alternatively, if you're riot police trying to suppress a crowd without killing them, you'd use bullets or shotgun shells loaded with rubber, foam, wax, plastic, bean bag rounds, or tear gas with reduced propellant. If it hits you in the head or in an unlucky spot, you might die from blunt force trauma but it's less lethal than an actual bullet.

===Types of bullets===
As a short note on bullets, its important to know that just because a bullet can easily penetrate armor doesn't mean its a definite upgrade over everything else. If a hard bullet like the FMJ or AP penetrates the human body and exits in the same shot; its gonna hurt like hell but unless that bullet was in the 12.7mm (.50 caliber) category or it hit something important like a lung or the head; the target has a good possibility to survive through a combination of medical aid, hormones (adrenaline in fight or flight), and willpower (with the side possibility of stimulants), and even still continue to fight onwards if they're that [[Ork|dead 'ard]]. That said, if a 12.7mm round came tearing through your body; it has enough momentum to potentially rupture a good chunk of your insides which is ''very'' lethal, but 12.7mm guns are generally not mainstay (these are guns like the Desert Eagle, M2 Browning, or M82 Barrett), so unless you're a real-life action hero, a turret gunner, or a counter-sniper; its unlikely for you to have access to these behemoths.

Likewise, if a soft bullet like the JHP or SP penetrates the body, then which expands, fragments, and/or tumbles inside; in short internal and external bleeding would be the most urgent of the target's concerns, with ruptured organs and torn muscles leaking like a broken sewage pipe, thus making HP lot more lethal and debilitating. That said, soft bullets fragment easily and body armor proportionate to it's caliber can reliably stop soft round. That said even if armored; the target is still gonna feel the impact of the bullet's force hitting against his body, and that still has the potential of killing someone if the circumstances are right (although its still unreliable).

In the end, a bullet is either specialized where it's only effective against either armored or unarmored targets, or a special combination that renders it effective against both types (although these require an experienced smith to manufacture properly).

*Ball - though if we start talking bullets we need to start with the first bullet: the lead ball, from where we derive the common term for bullets as 'rounds'. It's...just a lead ball though, not much to say about it. The balls were hand made, often by soldiers themselves since lead has such a low melting point, with the molds often being unique to each gun. This used largely the same process that was used for [[Sling]] bullets since antiquity. These early bullets would be smaller then the barrel and so would often 'rattle' down the barrel due to the ill fitting, which combined with a lack of rifling would mean early guns were horribly inaccurate (you could still reliably hit your targets at ranges between 70 and 100 meters, this is only true if we compare it woth modern firearms, which have their range measured in hunderes, if not thousands of meters). If one used a larger bullet that better fitted the gun, one could use rifling, but this required, (see above) hammering the bullet into place to make sure that there were no gaps.

*Minié ball- The first bullet we would know as a 'bullet', and the first truly distinct from a lead ball. A Minié ball is a conical bullet with a concave hole in the base. When fired the base flared out from the pressure of the blast, letting it engage with the rifling of the gun. This meant that it formed a seal with the barrel making it incredibly accurate, while not needing to be tightly hammered down the barrel. The best of both worlds. Combined with it's large size these things were lethal on the battle field maiming and crippling an entire generation of soldiers during the US civil war.

*Full Metal Jacket (FMJ)- Generally a lead or steel bullet encased in a soft metal such as copper. Acts a sort of lube as well as preventing fouling of the barrel. Depending on design, has a potential to fragment post impact, shredding internal organs.
**Synthetic Jacket- FMJ ammo with a plastic jacket, which has the advantage of reducing cleaning requirements and safer when hitting steel at the cost of various things not really relevant in practice ammo. Currently only in handgun calibers and only made as practice/match ammo (though some hollow points and AP rounds do also use polymer jackets).

*Hollow point (HP)- The hollow section in the center makes the bullet expand on impact, creating a bigger hole in its victim at the expense of being less effective against armored targets. That being said, the decreased penetration also makes it safer to use in situations where over-penetration could be dangerous (e.g. on an aircraft). Certain designs have bladed tips on expansion, causing additional cutting and bleeding too. It was banned from military use by the Hague Convention of 1899, so restricted to police, civilians, and, as of 2017, the United States Armed Forces (The US didn't sign that provision, but previously stuck with FMJ even after mass production became feasible for the sake of NATO compatibility).

*Semi jacketed Hollow point (SJHP)- Same as a hollow point, but has a copper jacket to help reduce fouling.

*Jacketed Hollow Point (JHP)- Same as above, but fully covers the bullet down to the tip.

*Wad cutter (WC)- Flat tipped bullet. Not very aerodynamic but it leaves a big hole to help tell you where you hit the target. Generally for closer range paper targets as they lose velocity very quickly due to the drag on them.

*Semi Wad Cutter (SWC)- Like the wad cutter, but more aerodynamic.

*Armor Piercing (AP)- As name implies, intended to penetrate armor, be it person or equipment. However, this ultimately depends on what gun you're shooting from and what armor you're shooting at. A 9x19mm AP steel round coming from a 4" barrel will do diddly to NIJ Level IIIA, where as a 7.62x51 AP flying out of a 24" barrel will punch through it easy as you please. Modern AP rounds are often jacketed in plastic, but this is purely to protect the barrel (turns out sending something meant to destroy steel through a steel barrel results in a wrecked barrel) and adds no armor piercing quality.

*Saboted light armor penetrator (SLAP)/Saboted bullets- Think of the discarding sabots fired from a M1 Abrams or a saboted slug of a shotgun, but redesigned to be fired like a standard rifle round. The sabot is designed to the grip the rifling until it leaves the barrel, then discard after leaving the barrel. This would leave the penetrator or bullet with a high velocity while providing a sufficient spin to the bullet to keep it stabilized in the air. With a higher density and/or thinner bullet, they can potentially penetrate better than potentially even APHE. Likewise for handcrafted bullets, they provide higher velocity for a smaller bullet in a cartridge intended for a larger caliber.

*High Explosive incendiary (HEI)- Explosive tipped munition. Generally for larger rounds (think 7.62 and beyond), they typically are meant for non-infantry targets such as light vehicles, light aircraft, and barriers, showering those inside with speeding shrapnel. Despite their implication, they might not work as well as one might think against hard target.

*Armor Piercing Incendiary (API)/Armor Piercing High Explosive (APHE), High Explosive Incendiary Armor Penetration (HEIAP)- Designed with the intentions of penetrating hard targets that HE rounds can't do alone and being anti-material in general, API and HEIAP are the answer to those targets. Generally have sufficient power in and behind the bullet (think Raufoss Mk.211), it will penetrate body armor and light vehicles with awe-inspiring ease.

*Soft point or semi jacketed - Like a FMJ, except the tip is exposed. Designed to have the reduced drag of a FMJ, while expanding upon hitting a target similar to a hollow point. Generally designed for hunters in mind.

*Ballistic tip - Similar in performance to the semi-jacketed bullet, but rather than being a solid core of lead it is designed like a hollow point, but with a plastic tip at the end to reduce drag and ensure expansion.

*Ratshot - made for smaller-caliber guns and is basically birdshot for rifled barrels. The tip is a plastic cap that contains a small amount pellets, typically within the 1.5mm range. As the name implies; the gun is primarily designed for shooting pests and small animals like rodents and grass snakes. You can use it to shoot at larger pests like coyotes or humans, but it's woefully underpowdered for the job.

*Matchgrade - ammo designed primarily for shooting competitions and/or extreme feats of marksmanship. Very expensive compared to popular alternatives and impractical for common use, but you get what you pay for: a cartridge produced with the finest minds R&D could muster, subjected to much more rigorous batch testing and quality control, and guaranteed to shoot a bullet as far and accurately as physics would allow. Rounds alone do not make an accurate firearm however, so the gun it's chambered in has to be well-maintained and designed for precise shooting in mind.

*Tracer - a regular bullet coated in pyrotechnic coating that ignites when fired. These are most commonly used with machineguns (every fifth round in a belt, to be exact) since it's useful for the gunner to accurately see where all his bullets are going, as well as make it clear to any enemies he's suppressing just who he's aiming at. Similarly rifle magazines are often loaded with tracers at certain intervals to provide indication of remaining ammo. Of course, the caveat is "tracer's work both ways" as they can give away your position; this can be mitigated by using "dim" tracers that can only be seen through night vision goggles. Sometimes also used by spotters or commanders to mark a specific target. They can potentially set fire to objects, if the incendiary compound hasn't burned out yet on impact.

*Less-lethals - Commonly known as 'rubber bullets' even though they're made of other substances such as plastic, foam, wax, and beanbag rounds for shotguns these days. Used in riot control and such, where the shooter isn't allowed to kill. The key word is "less", however. They hurt like a sonovabitch and can still kill in the wrong circumstances when they hit you in the head or a sensitive area, though. Some, such as blanks or wax, are also mixed in with real rounds before being loaded in weapons of a firing squad to make the responsibility of an execution unclear amidst the shooters. Airsoft this ain't.

*Silver - Pure fantasy, but common in there to counter supernatural creatures weak to silver. Silver bullets would suffer from many problems that rarely get mentioned in fiction. Chief among these are the cost, that silver shrinks when cast (so it's really hard to get the right size and shape), and that silver is too soft to engage rifling so even if you get the right size accuracy will be terrible. [[Monster Hunter International|More /k/ aligned works]] solve these issues with solutions like sabots (which helps accuracy but still worse than real bullets), ballistic tips made of silver and frangible bullets filled with powdered silver (instead of the typical competitively cheap metal).

===Types of Rounds===
Apart from the traditional type of rounds, here are some unique ones for reference.

*Blanks - What you commonly see loaded in movies. Blanks are basically that; the round has a primer and powder, but the bullet is just a paper or plastic sheet (or "wad") designed to keep the powder in, so you get the sound of a gun going off, but not the damage. That said, blanks ''can'' still kill people, that wad is still powerful enough to liquefy organs and break bones if you were dumb/desperate enough shoot someone with a blank at close range (plus the gas itself is hot enough to cause severe burns at that range). Movie armorers make a point of demonstrating this with things like fruit before letting anyone touch blank firing guns. This is why instead of blank-firing guns, actors will use flash paper guns at close range for safety. There's also blank ammo specifically designed to make as much noise as possible for the purpose of disorienting and intimidating people in an area. In a military sense blanks do have a use: typically for turning your rifle into a grenade launcher, using the expanding gases to launch a grenade held at the muzzle by a cup. Blanks can't cycle a gun's firing mechanisms in the same way as standard bullets can, so self-loading guns that fire blanks have to either be made specifically to fire them or be equipped with an adapter that compensates for the reduced pressure.

*Caseless - An old but futuristic concept, a caseless round has everything required for the bullet to be launched, inside the bullet itself. [[Memes|That's 65% more bullet, per bullet.]]This removes the need for guns to eject spent shell casings after every shot, reducing weight and ammo costs. While this has been pioneered since WW2 and a few prototype examples for it were already developed (like the G11); caseless rounds are still determined to be too unreliable for field combat use in comparison to traditional ammunition, so as of today their use is largely limited (mainly to grenade rounds like the Russian VOG-25 grenade). Their biggest disadvantage is that ammo cases normally transports a large amount of heat out of the weapon, and, if you have paid attention in your physics class, you know that heat always has to go ''somewhere'', so with caseless ammo, it naturally goes into the weapon, making it prone to overheating and dangerous cookoffs, unless the ammo somehow counteracts this, making it more complex and therefore expensive in the process, and if you've at one point in time interacted with any branch of a national government, you know that the word "expensive" usually spells doom for any project that it is attached to.

*Gyrojet - A unique but largely impractical cartridge in the gun circuit, WH40K's famous [[bolter|boltguns]] run on the same concept as the gyrojet. Basically, the bullets are miniature rockets that build up speed as they travel, capable of exceeding the speed of sound after traveling 60ft. While the idea sounds cool; gyrojets were ''required'' to gain minimum distance to achieve their full effect (if you fired at point-blank for example, they didn't really do much), had a design flaw in their propulsion system that made the rockets prone to corkscrewing off-course, and were highly temperamental to environmental conditions, not to mention the costs. At the end the concept was a bust as it didn't really do a lot that couldn't be achieved with traditional small arms for cheaper. Still GeeDubs thought it was nice and became the basis of how boltguns work, where it's largely the same but with more techno-flubdubbery and "because future".

*Magnum - Unlike what vidya gaems portray, magnums aren't really super-mega handguns of death. A magnum round is basically a parent cartridge that's been enlarged so it does more damage due to a combination of larger mass and more powder used (so it flies faster and hits harder), and this can be anything from the .357 magnum handgun round used by revolvers, to the large caliber .338 Lapua and Winchester magnum rounds used for precision sniper rifles.
** Special - An earlier equivalent. The only two to see continued existence are .38 special and .44 special which also went from black powder to smokeless powder, both of which coincidentally have even longer magnum variants; however both are lengthened only as a safety precaution to make them different, as smokeless powder left plenty of room for more powder.

*Overpressured - Designated as "+P", overpressured rounds still uses the same cartridge (unlike the magnum), but is loaded with higher-pressure powder that releases more energy when fired. It sounds like a nice way to up your damage, but guns have a level of pressure they can tolerate, and if your gun isn't designed to do such and you use +P rounds; you run the very high risk of destroying your gun (and the rest of your body if you're that unlucky). There are guns that are proofed to fire +P and +P+ ammo but it is typically used in SMGs. Certain batches of surplus ammo will blow up guns because they were made to be used in more robust SMGs and not commercial pistols, poorly stored, or just plain poorly made.

*Subsonic - Rounds designed to shoot slower than the speed of sound to prevent creating the loud cracking sound a projectile makes when it goes beyond 345m/s, making them more stealthy. There's three ways to go about this. The first is to put less powder in the round, or use specialized one that explodes with and imparts less energy (although this may cause problems for self-loading guns, who are not designed to cycle using less powerful ammo). The other is to make the bullet much heavier than usual so the standard powder load doesn't have enough energy to have the bullet break the sound barrier, although this translates to slower projectile speed and lower range, but increased chances of armor penetration as heavier bullets retain energy much more efficiently than lighter ones. The last is a combination of the two methods. Subsonic munitions are primarily used in silenced weapons for their sound-reduction benefits (the most extreme case of which is that only the cycling of the gun can be heard, the gunshot is virtually inaudible), although some take advantage of certain subsonic rounds' heavy bullets and low-energy for defeating armored opponents at close range (as the lower energy translates to lower chances of overpenetration, which AP bullets have a tendency of doing when tearing through non-armored parts of the body).

===Types of shotgun loads===

*Buckshot - The shell is filled with lead or steel pellets, each of which is typically around 15mm each (it ultimately depends on the bore), that spread out once discharged. Poor at penetrating armor and limited effective range comparison to other firearms as the pellets scatter and the pellets are too small to do serious damage individually (Although do note that unlike what the vidya gaems portray; a decent 12G shotgun loaded with buckshot is effective upto 30-50m, not just in point-blank range); but they do cover a fairly large radius and the force of 8-12 pellets impacting against your body will send you tumbling and rolling on the floor in agony, even if they don't penetrate.

*Birdshot - Similar to buckshot and more pellets, but the pellets are smaller (5mm and less, although still depends on the bore). As their name describes; the ammo is designed to pelt down birds by [[Ork|throwing as many bullets at the target and hoping atleast a few of them hit]]. You can use them against non-avian targets aswell and they'll do something, but they don't pack the punch you'd like and don't expect them to dent body armor too much. Their ineffectiveness against human targets [[Wikipedia:Dick Cheney hunting accident|was demonstrated by a (possibly drunk) Vice President of the United States]] when he shot an old guy in the face with some and the only lasting damage was the voice.

*Slug - Instead of multiple pellets; the gun fires a single, heavy lead projectile, similar to how traditional ammo works. Because shotgun barrels are not rifled; slugs do not have the range nor accuracy rifles do, but because of their weight and the shotgun's fairly large caliber; they're fully capable of crushing their way through armor at close range. Slugs are typically used for hunting large game in areas where rifle ammunition isn't allowed due to the risk of overpenetration.

*Breaching - A specialized variant of the slug round, breaching rounds are designed specifically to destroy door locks at extremely close range. Generally composed of very dense powdered steel held together with wax.

*Less-lethals - Designed for riot control where the shooter isn't allowed to kill; the bullet is either made of rubber, paint, or beanbags designed for minimal penetration, while the powder used in the rounds is less to reduce the projectile's velocity. The end result is a bullet designed to simply cause shock and pain to the target in order to incapacitate them long enough to be arrested and not rejoin the fight in the meantime. That said, you're still talking about launching an object at someone at speeds similar to cars speeding on a highway; so hitting vulnerable parts of the body like the head, neck, or ribs can still result in a fatality. On the flip side, anyone wearing bullet-resistant armor won't be affected too much.

*Chain-shot - Typically reserved for olden cannons, the chain-shot is two cannonballs linked with a chain. The spinning contraption was intended to tear through a ship's mast and sails. Obsolete as fuck, but it is still possible to replicate this with shotgun ammo. Basically you tie two pellets or slugs together so that when they're discharged; they're basically flying garrotes. Awesome, but because of how unpredictable bullets are while in flight, it's highly impractical for combat use.

*Flechette - Buckshot, but instead of pellets; the shell is loaded with small metal darts. They achieved better penetration and range than traditional buckshot; but because shotguns aren't really designed as precision weapons; they were highly impractical for combat applications. They destroyed barrels and tended to deflect off really silly things like raindrops.

*Explosive Rounds - The shell contains an slug that explodes upon impact, capable of using anti-armor or anti-personnel shells, basically turning the shotgun into a portable grenade launcher. Not as powerful as the real thing, but invaluable when you need accurate explosions but not the excessive collateral damage or restrictive weight and mass. Has seen some use in rifle rounds on the eastern front of World War II as well as in .50 BMG (officially for use on objects, not people).

*Dragon's Breath - An odd type of ammo. DB shells are loaded with magnesium pellets. When discharged; they create a short but hot burst of fire that burn at temperatures upto 1,600°C. While not really used much for conventional combat due to its status as an incendiary weapon, blasting a person with this at close range will create about the same results as a giant fire-breathing lizard incinerating an unlucky knight to death, hence their name. Also destroys barrels, as dragon's breath burns hotter than the melting point of steel, and close to the melting point of chromium (two of the most common metals used in gun parts).

*Misc - Shotguns aren't really picky with ammo since they are manually operated and don't depend on a gas seal as much; just about ''anything'' can be used for bullets if worse comes to worse/you're bored. Could be lego pieces, could be old hard candy, solid scrap,frozen meat [https://www.youtube.com/watch?v=7-n4bxxn9gA or even glass]. They can also fire flares (but need stronger propellant and an unchoked barrel to avoid getting stuck and melting the barrel). Hell, it can be a Sly Marbo tabletop figure if you could fit him inside a shell and prevent him from disintegrating from the force while exiting the barrel, the choice is yours. (More likely blow up your gun as Sly refuses to die and gives you the finger for trying.) Incidentally this unfastidious in ammunition also means that in a fantasy setting you can basically load anything you want down the barrel of a shotgun to deal with basically any monster that had a weakness. Wooden stakes for vampires, Cold iron for fae, silver for werewolves, the aforementioned dragon breath for flame vulnerable monsters, salt if that's a thing demons hate in your mythos, freeze holy water into ice and you could still likely shoot it with a sabot. Basically shotguns should be the go to for the modern murder hobo.
