What Do Airsoft Bullets Look Like

Low-quality 6 mm 0.12 g plastic airsoft pellets

Airsoft pellets are spherical projectiles used past airsoft guns. Typically made of plastic,^[one] they unremarkably mensurate around 6 mm (0.24 in) in diameter (though selective models use 8 mm),^[i] and weigh 0.12–0.40 g (i.nine–vi.ii gr), with the most common weights existence 0.12 g and 0.20 g, while 0.25 g, 0.28 thousand, 0.xxx g and 0.40 yard pellets are too commonplace.^[i] Though frequently referred to as "BBs" amidst airsoft users, these pellets are not the same as either of the iv.5 mm metal projectiles that BB guns burn,^[2] or the iv.6 mm (0.180 in)-sized birdshot from which the term "BB" originated.^[3]

Variants [edit]

Although the bulk of pellets bought and used are simple spherical projectiles fabricated of plastic, some of the following special varieties can be used to give a player an advantage, such every bit higher quality pellets.

High quality Airsoft pellets.

Biodegradable [edit]

Biodegradable pellets are available, and are often required by outdoor fields where sweeping is not an selection. Conventional pellets pollute the surroundings, as almost non-biodegradable pellets have a mineral or petroleum-based middle, coated in non-biodegradable plastics, thus ensuring they will stay in the environment for several hundred years if not collected. Biodegradable pellets are made of various types of resin, often adult for the agricultural industry, and better makes are certified as compostable. Commonly used plastic resins include polylactic acid or polylactide (PLA) which is based on renewable materials like corn products and a molecular formula of (C₃H₄O₂)_n.^[4] In that location is a mixture of degradable processes being used, such as soil microbes and photosensitive degradation. Biodegradable pellets are currently being produced with all the characteristics of the best of the conventional, with homogeneous resin construction.

Virtually high-quality pellets are available in a not-biodegradable version, every bit well as a biodegradable version that costs slightly more than. Both bio- and not-biodegradable pellets are popular and widely available.

Translucent [edit]

Tracers [edit]

Glow-in-the-dark pellets, known as tracer pellets, tin be used in conjunction with a device that "charges" the pellets past flashing them with a outburst of calorie-free before leaving the butt so that they remain luminescent in flight for use during nocturnal games/operations. This tracer unit is commonly hidden from view, oftentimes disguised as a suppressor, or is included inside the magazine or hop-up unit of measurement. There are also biodegradable tracer pellets available.

Non-traceable pellets [edit]

This blazon of pellet is dark-colored so that the opponent has a tougher time spotting the pellets' origin, as the most common pellet color is white, which makes it easy for the opposition to spot the shooter by post-obit the trail of pellets. Two major problems of this variant of pellet are that there are few high-quality pellets in this color and the shooter has a difficult time seeing his own trail of shots.^[5]

Pigment-spherical projectiles [edit]

Pigment-filled pellets are also bachelor, called "paintballs", which are very similar to those used in paintball. Airsoft models equipped with the hop-upward projectile stabilizing system are not able to use these, as the thin shells are liable to intermission in the barrel, soiling it with paint. These special pellets are as well incompatible with airsoft models using mechanized feeding systems, such equally loftier chapters magazines, for the same reason. With some companies, the apply of paintballs voids the airsoft gun's warranty; paint may go into the mechanical workings of the airsoft gun and harm parts beyond elementary maintenance. These problems may exist stock-still by removing the hop-up unit, which tin can void the warranty, and also switching to a low or mid-capacity mag with no mechanized feed.

Markers [edit]

A specialized pellet coated in a pulverization that leaves a small colored mark when it strikes a surface. The powder deposits from these pellets are left in any function of the airsoft gun or storage unit that the pellet comes in contact with; build-up over time, without cleaning, tin crusade malfunctions or damage to moving parts.^[vi]

Made from 100% silica, the material in these pellets is very evenly distributed, improving flight characteristics. Some accounts indicate that these pellets are capable of breaking drinking glass and industry-standard protective eyewears. Due to safe concerns and reports of injuries caused by this type of pellets,^[6] it is commonly prohibited in professional airsoft facilities.

Metallic [edit]

Metal pellets are besides marketed for use in airsoft guns. These pellets are heavier and harder than conventional polymer pellets, and the impact from a metal pellet can hurt players. Rubber concerns make metallic pellets suitable simply for target shooting. The added weight reduces the effect of crosswind on the pellet, imparting more accuracy when fired at longer ranges in outdoor environments where wind would significantly modify the trajectory of traditional pellets. Many airsoft locations where players can pay to play against others prohibit the utilize of metallic pellets due to the fact they are more likely to penetrate skin. Metallic pellets are by and large used in a standard pump-action or carbon dioxide-powered BB guns.

Ceramic [edit]

Created from laboratory-grown crystal lattice structures, these pellets are individually machined to precise specifications that ensure uniform weight, dimensions and surface shape. This precision and uniformity provides ideal ballistic performance and consequent flying patterns. The manufacturing process and materials are much more plush than molded polymer pellets – as a result, ceramic pellets are considerably more expensive than standard airsoft pellets. The material is able to defeat standard middle protection due to the weight and higher energy required to propel it, thus unsuitable for use against other man targets

Pellet mass [edit]

Pellet mass is an important factor when choosing pellets. The pellet'due south mass influences several aspects of pellet performance:

Velocity: Lighter pellets reach college velocities, but are more prone to influence from external factors like current of air. Lighter pellets also decelerate (lose velocity) faster than heavier pellets. Due to the increased momentum of a heavier pellet, it volition hitting harder than a lighter one. In addition, while evidently counterintuitive, lighter pellets can actually decrease range due to the mechanics of hop-up.
Free energy: Lighter pellets have college kinetic energy in lower-velocity guns, but heavier pellets testify trends to have higher kinetic energy in guns that shoot 620+ feet per 2d.^[seven]
Trajectory: The curvature of a projectile (trajectory) determines its range and lighter pellets typically result in much more curved or unpredictable trajectories, although using a hop-up can flatten, regulate and extend trajectory.
Hardware: Heavier pellets may require a more powerful airsoft gun and often necessitates upgraded springs and other gun parts.

A actor's selection of pellet mass is governed by their gaming way (assaulting vs. sniping), the airsoft gun used (internal parts), game venue status (in/outdoor) and size, and muzzle velocity regulations.

Too, the quality of the individual pellets may influence choice of price-range or manufacturer. Low-cost pellets are frequently considered to have such negative characteristics as residual plastic from the moulding process (flash); lower impact resistance and some deviation from perfect spherical shape. Cheaper pellets are known to shatter when fired, which can cause irreparable damage to the internals of the gun. Higher cost BBs mostly have a smoother finish, are more impact resistant and are perfectly spherical.

6 mm airsoft pellets [edit]

6 mm is the industrial standard size used in about all leap, electrical and gas airsoft guns. A wide variety of pellet masses are also bachelor for dissimilar usages.

0.11 thou – Manufactured by HFC, same use as .12 gram. Extremely Uncommon.
0.12 grand – Extremely common, standard weight for all low-course AEG's and spring guns. Non to be used in whatever pocket-sized arms across low-cost, low quality replicas firing under 250 fps. These pellets are notorious for breaking within high-powered guns because they are not hollow inside. The low weight of this pellet as well causes information technology to be extremely inaccurate because they are easily afflicted by the slightest of breezes.^[8]
0.135 g – Same uses as 0.12 g. Extremely Uncommon. MFI standard. Non to be used in most guns.
0.15 g – Aforementioned uses as 0.12 thousand. Uncommon. Made only by Air Venturi, Red Jacket, Elite Strength, and Blackness Ops USA.
0.sixteen grand – Essentially the same as the 0.xv g pellets. Made only by Air Venturi.
0.xx g – Second-well-nigh common weight. Standard for all chronograph tests in regions, where gun power output is measured in anxiety per 2d (FPS). AEGs are able to use these, yet, most players volition use heavier masses due to the increased accuracy and range. Biodegradable versions made by Green Devil or G&G being ane of the most popular makes in the Scandinavian countries and many other parts of Europe & Britain.
0.21 k – Homemade by covering .20 yard with pencil lead. Not bad for "paintball" merely leaves residue in butt.
0.22 k – Available from Pyramyd Air.^[9]
0.23 yard – Heavier pellets for AEGs. Blends speed of 0.twenty m with range and accuracy of 0.25 g. Made pop past Tsunami Airsoft. Used less now in favor of .20 one thousand & .25 g
0.24 thousand – Only known manufacturers are Airstrike (a subsidiary of Daisy) and Crosman
0.25 g – Third-most common weight, especially popular for the higher-powered AEGs used in America. This is the heaviest mass for lower-powered AEGs, blowback and spring guns. Tokyo Marui standard AEGs, gas and jump guns are set up at the factory for 0.25 gram pellets, and they usually include a packet of 200 of these with the gun. These are available in bio- and non-biodegradable versions from many sellers including Valken, EliteForce, 6mmProShop and Matrix.^[10] Biodegradable versions made by Light-green Devil or G&G being one of the most popular makes in the Scandinavian countries and many other parts of Europe & United kingdom of great britain and northern ireland.
0.26 g – Fabricated by TSD in biodegradable form.
0.27 g – Made by Bioval BBBMAX. They are (ostensibly) considered to be of the same course, if non college than the Maruzen SGM, while existence significantly less expensive.
0.28 grand – Most used weight in Northern Europe. Suitable for modern standard AEGs. Typically cheaper than 0.30 g just yields similar performance. Biodegradable versions are made by most manufacturers.
0.29 g – Maruzen Super Grandmaster pellets, designed for their Air Precision Shooting series of airsoft guns. O
0.xxx m – Standard mass for well-nigh sniper rifles. Also recommended weight for tuned AEGs. Have become more than common in recent times with some of the top brands like Bioval and Bioshot, Biodegradable versions made by various manufacturers including Thousand&G and Tokyo Marui.
0.32 g – Besides standard for sniper rifles. Offers first-class balance of velocity and stability for most leap and gas sniper rifles. These are available from Evike, Aristocracy Force, and other BB manufacturers.^[11] A well-known brand is Goldenball.
0.36 g – Heavier pellets for sniper rifles. Slower, only have loftier stability. Produced past Madbull Airsoft, among others. BB Bastard manufactures a ceramic pellet in this mass class.
0.40 g – Heavy pellets for airsoft sniper rifles. Mad Bull is a known producer. Fifty-fifty slower than 0.36 g just fifty-fifty more stable and maintains its velocity better.
0.43 thou – For the highest level of upgrades in spring and gas sniper rifles. Usually graphite-coated.
0.66 g – For extreme long-range shooting, not used confronting human being targets. This is a CNC-machined ceramic pellet fabricated past BB Bastard.
0.90 thou – Nickel-plated steel Bbs sold by UK's Abacus Claysports. Air gun grade, not used against human targets.

8 mm airsoft pellets [edit]

8 mm pellets are most normally used in gas-powered airsoft shotguns with high velocities.

0.27 g – Depression mass
0.34 grand (Normal) — Standard mass
0.35 m (Biodegradable) — Standard mass
0.40 g
0.45 g
0.48 k
0.50 chiliad
0.xc 1000 – Heaviest mass

Flight physics [edit]

Pellet muzzle velocity and energy [edit]

Velocity vs. energy chart for 6 mm Airsoft pellets.

The pellet speed of jump-powered and automatic electrical guns is determined in large office past the tension of the gun's master spring. Muzzle velocity limits are between 90 and 120 chiliad/s (300 and 390 ft/s) for AEGs and 120 to 170 m/s (390–560 ft/southward) for single-shot spring sniper rifles.^[12]

For comparison purposes, iii.00 g (46+ three⁄10 gr) is the typical mass of a paintball pellet, and 0.two g (3+ nine⁄100 gr) is the standard for an airsoft pellet. At 3 k mass, a pellet flying at 100 m/s (330 ft/south) has 15 J of kinetic energy, while a 0.20 g has 1 J. It is important to distinguish that, in airsoft, the terminal impact energy is very close to the kinetic energy of the pellet because the collision is about completely elastic. On the other hand, in paintball, the pellet fractures upon affect, leading to an inelastic collision with energy loss, and thus the impact energy is smaller than the kinetic energy of the pellet. Yet, the typical impact energies of the airsoft pellet tend to be much smaller than of the paintball.

Pellet ballistics [edit]

bear on energy dependence on altitude of impact for a typical airsoft pellet

While a pellet's muzzle velocity is of import for safety proposes, information technology will lose velocity during flying due to elevate. The typical deceleration of a pellet of mass "m" and diameter "D" is given by the quadratic elevate:

A_{\text{drag}}={\frac {1}{2m}}\rho _{\text{air}}v^{2}\cdot 0.47\cdot \pi \left({\frac {D}{two}}\right)^{2}

where v is the instantaneous velocity of the pellet. For typical values of the pellet (g = 0.2 g, v = 120 1000/s, D = 6 mm), the drag can exist very high ( $576\ \mathrm {thousand} /\mathrm {s} ^{2}$ ), which means that the velocity decreases quite fast.

The above equation has a unproblematic solution for velocity vs. altitude:

v={v_{0}}{due east^{-s/{s_{0}}}}

where ${v_{0}}$ is the initial velocity, $south$ is the distance travelled, and ${s_{0}}$ is the altitude over which the velocity is reduced to $ane/eastward$ of ${v_{0}}$ :

{{s}_{0}}={\frac {8m}{{{\rho }_{air}}\cdot 0.47\cdot \pi \cdot {{D}^{ii}}}}

In particular, for typical values and neglecting wind effects or hop-upwardly usage, a straight shot from a summit of one.viii 1000 (5.9 ft) has a range of 34 grand (37 yd). On ground hit, the touch on energy of the pellet is 0.1 J. Nevertheless, the same shot at shut quarters (e.g. 5 chiliad distance) has an impact energy of 1 J (come across effigy).

Dangers to humans [edit]

Airsoft pellets travelling with sufficient velocity can leave small superficial wounds when hitting exposed pare. While this can be painful, these wounds are typically closed contusions and heal quickly without needing any medical attention. Even so, pellets can crusade more than serious impairment to the more than vulnerable parts of the torso, such every bit the eyes and ears. Lower protective face masks are recommended during airsoft matches to shield players' nose, mouth, teeth and ears, and goggles or other protective eyewear are mandatory for centre protection.

The critical velocity required for pare penetration can be calculated using the formula:

v_{\text{cr}}=162.1e^{-0.38{\sqrt {yard}}}

where m is the mass of a spherical bullet, in grams. Penetration is defined here equally inbound the pare to a depth of more than one-half of the spherical pellet's diameter.

Accordingly, a typical 0.20 1000 airsoft pellet will penetrate the skin at 136.7 m/south (448 ft/s). Considering many high-finish AEGs, jump- and gas-powered airsoft guns can accomplish such velocity at close ranges, many airsoft venues gear up strict limits on the maximum cage velocities allowed on the field, requiring each player to undergo a chronograph test prior to participating in a game. Some venues even have restrictions on minimal appointment distances, where shooting at opponents nearer than a set altitude is prohibited, and a "blindside blindside" rule (players imitate firing past shouting "bang blindside" instead of really firing the weapon) is often implemented.

The following excerpts from the United Kingdom Parliament'south "Principles of Firearms Command"^[13] expound on the level of danger involved with low-free energy projectiles:

"25. The Firearms Act 1968 defines a firearm "a lethal barreled weapon of whatever description from which whatsoever shot, bullet or other :missile tin be discharged".[51] In this context, a "lethal weapon" means a weapon capable of firing a projectile with sufficient :force to inflict more than than a trivial injury, i.eastward. with a strength sufficient to puncture the peel.[52] The forcefulness with which a firearm :is able to deliver a projectile is normally expressed in terms of the kinetic energy information technology generates at its muzzle—the "muzzle energy". :This energy is usually expressed in units of foot-pounds (ft·lbs) or joules (J).[53]

"26. The Home Office and the Forensic Science Service considers that the lowest level of muzzle energy capable of inflicting a penetrating wound is one foot pound force (ane.35 J): below these ability levels, weapons are "incapable of penetrating even vulnerable parts of the torso, such as the middle".[54] However, more contempo assay by the Forensic Science Agency for Northern Republic of ireland has indicated that a more than reasonable assessment of the minimum muzzle free energy required to inflict a penetrating wound lies between ii.2 and iii.0 ft·lbf (3 to 4 J).[55] We will deal more fully with this discrepancy at paragraphs 123 to 130 beneath."

"123. The power level at and above which an air weapon is considered a firearm in law is presently set at i ft·lbf. However, the Forensic Scientific discipline Bureau of Northern Republic of ireland has more recently assessed the ability level at which a barreled weapon is capable of inflicting a lethal wound every bit between 2.2 and 3 ft·lbf, and the Secretary of State for Northern Ireland has proposed that the police force relating to firearms in Northern Ireland be amended to take this into business relationship.[201]"

On another document besides regarding firearms, "The Eleventh Annual Study of the Firearms Consultative Committee", the penetration levels lies between 2 and 3 J based on a research for US Regular army and DiMaio's piece of work in "Minimal Velocities Necessary for Perforation of Pare by Air Pellets and Bullets, Journal of Forensic Sciences".
