8th Minute (AIRSOFT SPECIAL) Ballistics and Speed

Kinetic energy is the energy that is transferred from the pellet to its target upon impact. One joule of energy will be transferred by a 0.20 g BB at 100 metres per second (330 ft/s).^[1] A typical set of limits on guns might be 100 m/s (330 ft/s) for CQB, 125 m/s (410 ft/s) for outdoors, and 175 m/s (570 ft/s) for bolt action sniper rifles, all measured with a 0.20 g BB. The amount of kinetic energy depends on the weight of the BB and how fast the gun can propel it. Certain places play "no velocity limit" games.

In the United Kingdom and Ireland, the energy limit for Airsoft guns is usually one joule (100 m/s with a 0.20 g, 6 mm BB) regardless of the type of game play.^[2]

Most Airsoft guns are capable of shooting from 50 m/s (160 ft/s) to 125 m/s (410 ft/s), though it is also possible to purchase upgraded springs for some Airsoft guns that will enable up to 180 m/s (590 ft/s) projectile velocities.^[3]

A hop-up unit, if present, puts backspin on the BB, generating lift and giving it a greater effective range. The range of any Airsoft gun depends on both the muzzle velocity and the amount of hop applied. Airsoft guns can have a range of 75 metres (250 ft) or more with the right combination of power, barrel, and ammunition as well as a good hop-up unit. A good hop-up unit can sometimes double the range.
