Air guns are older then think

Many of you is thinking that air guns are new but:::
"Air guns represent the oldest pneumatic technology. The oldest existing mechanical air gun, a bellows air gun dating back to about 1580, is in the Livrustkammaren Museum in Stockholm. This is the time most historians recognize as the beginning of the modern air gun.

In the 17th century, air guns, in calibers .30–.51, were used to hunt big game deer and wild boar. These air rifles were charged using a pump to fill an air reservoir and gave velocities from 650 to 1,000 feet per second (200–300 m/s). They were also used in warfare; the most recognized example being the Girandoni Military Repeating Air Rifle."

So we should start looking into Air guns for hunting using 22cal or biger cal, one of the best places to start checking would be Pyramyd Air. Pellets are cheaper than ammo
