The first air guns were developed as early as the 1500s. They have been used in hunting, sporting and warfare. This is the time most historians recognize as the beginning of the modern air gun. At that time, thirty one spring 2013 catalog pdf had compelling advantages over the primitive firearms of the day.

Moreover, they were quieter than a firearm of similar caliber, had no muzzle flash, and were smokeless. Thus, they did not disclose the shooter’s position or obscure the shooter’s view, unlike the black powder muskets of the 18th and 19th centuries. In the hands of skilled soldiers, they gave the military a distinct advantage. A skilled shooter could fire off one magazine in about thirty seconds.

The rifle was said to be capable of 22 aimed shots per minute and had a rifled bore of 0. One of the first commercially successful and mass-produced air guns was manufactured by the William F. 73 cents in its catalog. King” model air rifle until 1935 before ceasing operation all together in the 1940s.

In terms of power modern air guns are capable of delivering high levels of energy, the recently showcased Umarex Hammer fires a . The distances FT and HFT competitions are shot at range between 7. FT, with varying sizes of ‘reducers’ being used to increase or decrease the size of the kill zone. In the UK, competition power limits are set at the legal maximum for an unlicensed air rifle, i. These methods are used in both air rifles and air pistols.

Before shooting, the user need to manually cock the gun by flexing a lever connected to the pump assembly. The effort required for the cocking stroke is usually related to the designed power of the gun, with higher muzzle velocities requiring a stiffer spring and hence a greater cocking effort. Shortly after leaving the barrel, the supersonic pellet falls back below the speed of sound and the shock wave overtakes the pellet, causing its flight stability to be disrupted. Drag increases rapidly as pellets are pushed past the speed of sound, so it is generally better to increase pellet weight to keep velocities subsonic in high-powered guns.
