Airsoft Pellets

• 0.12 g - Used by all low grade weapons such as some spring pistols (which can use .20) and mini electrics. High velocity and low stability. Not to be used in high end AEGs such as Tokyo Marui and Classic Army


• 0.15 g - Same uses as 0.12 g. Uncommon. Not to be used in high end Automatic Electric Guns (A.E.G.s) such as Tokyo Marui and Classic Army


• 0.16 g - Essentially the same as the 0.15 g pellets. Very uncommon.


• 0.20 g - Standard weight for most Weapons . AEGs use these or slightly heavier pellets


• 0.23 g - Heavier pellets for AEGs. Blends speed of 0.20 g with range and accuracy of 0.25 g. Made popular by Tsunami Airsoft


• 0.24 g - An oddity. Only known manufacturers are Airstrike (a subsidiary of Daisy ) and Crosman


• 0.25 g - Heaviest weight for standard AEGs, blowback and spring guns. Tokyo Marui standard AEG, gas, and spring guns are set at the factory for 0.25 gram BB's, and they usually include a package of 200 of these with the gun.


• 0.28 g - For upgraded AEGs or sniper rifles. Significantly cheaper than 0.30 g but yields similar performance


• 0.29 g - Maruzen Super Grandmaster BBs, designed for their Air Precision Shooting series of guns. One of the most precisely ground and accurate BBs available, but cost more than other alternatives. These also can come in aluminum versions, which will hurt more than plastic.


• 0.30 g - Standard weight for most Sniper Rifles . Western Arms pellets for their gas blowback pistol series. Uncommon.


• 0.36 g - Heavier pellets for Sniper Rifles . Very slow but have high stability.


• 0.43 g - For the highest level of upgrades in spring and gas Sniper Rifles . Usually Graphite coated.


• 0.88 g - Possibly the heaviest type of BB available. Usually made of steel and comes with a polished finish. Rarely used and often hard to find.

• 0.27 g - Low weight


• 0.34 g (Normal)- Standard weight


• 0.35 g (Biodegradable)- Standard weight


• 0.45 g - Heaviest weight

• As for comparison purposes, 3.00 g is the typical weight for a Paintball pellet. At this weight a pellet flying at 90 m/s results in 12.54 J and 14.99 J for 100 m/s. Such energy levels and weight are not used on Airsoft, but comparing them with airsoft energy levels is useful to show the presence of different collisions in these sports. Higher energy but different collisions read Elastic Collision s (airsoft) and Inelastic Collision s (paintball) topics for further information.


• Red line in speed vs energy image is the usual Crony (chronograph) weight for 6 mm (0.20 g).

"25. The Firearms Act 1968 defines a firearm "a lethal barreled weapon of any description from which any shot, bullet or other :missile can be discharged". In this context, a "lethal weapon" means a weapon capable of firing a projectile with sufficient :force to inflict more than a trivial injury, i.e. with a force sufficient to puncture the skin.[52 The force with which a firearm :is able to deliver a projectile is normally expressed in terms of the kinetic energy it generates at its muzzle—the "muzzle energy". :This energy is normally expressed in units of foot-pounds (ft·lbf) 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 (1.35 J): below these power levels, weapons are "incapable of penetrating even vulnerable parts of the body, such as the eye". However, more recent analysis by the Forensic Science Agency for Northern Ireland has indicated that a more reasonable assessment of the minimum muzzle energy required to inflict a penetrating wound lies between 2.2 and 3.0 ft·lbf (3 to 4 J).[55 We will deal more fully with this discrepancy at paragraphs 123 to 130 below."

"123. The power level at and above which an air weapon is considered a firearm in law is presently set at 1 ft·lbf. However, we note above that the Forensic Science Agency of Northern Ireland has more recently assessed the power level at which a barreled weapon is capable of inflicting a lethal wound as between 2.2 and 3 ft·lbf, and the Secretary of State for Northern Ireland has proposed that the law relating to firearms in Northern Ireland be amended to take this into account. {Link without Title} "
