.... fired). The best of these develop about half the muzzle velocity of light firearms, are accurate enough for marksmanship training at ranges up to 100 feet (30 metres), and can kill small game. Darts with tranquilizing drugs may be fired to immobilize animals for handling or capture. An air gun projectile seldom carries beyond 100 yards (90 metres). Gas guns are comparable in power and accuracy ....

....e, handle them inappropriately. The air gun is a simple yet ingenious and effective weapon based on fundamental mechanics. The gun primarily employs a very stiff compression spring to transmit momentum to a light pellet. Here, a very clever method of transmitting energy to the pellet is used. It is not by collision but using the dynamics of compressed air. Most modern air guns are inexpensive BB....

....wered guns. They are pneumatic type, spring air compression system, and gas compression type (Di Maio, 1985). Death from an airpowered gun is rare. A review of English language literature reveals only a few deaths. Most involved children (Green, 1982). In most of the cases the point of entry was in the head." The authors after examining applicable mechanism design and use of airguns concluded....
