it depends what kind of gun you have, the average air rifle will kill a raccoon at its biggest if you area a good shot. but if u want to kill a pig which are tough animals you may need a big bore air rifle quackenbush makes good ones they can even take down deer.
Extremely unlikely You will just anger the pig.
If you are talking about a hand "air gun" Then most likely "NO" because the pellets only come in .177 .22 and .25 cal. Now if you are talking about an air rifle, then it is possible but you are looking at a high end air rifles in the PCP class of air rifles. The PCP's (Precharged Pneumatic Guns/Rifles) use a Scuba tank to charge them and can fire a pellet as large as 9mm, 45 and 50 Cal. These will bring down a boar, deer or moose. An example is the "Dragon Slayer" by Shin Sung. ( See: the link below.) There are quite a few makers of large bore air rifles on the market today. ( See link 2 Below.) and ( See link 3 Below) are but a few of the places that you can purchase them.
BTW Quackenbush made a 50CAL that is considered the rifle that all other PCP's are measured against. It was named the .457 Outlaw Long Action.
Yes
No, a pellet gun can't kill a bear it will only make it angry. There for it will eaither attack you or just ignore it.
It is passable to kill a cat in the right situation.
No... Corrected answer.-------------- It depends on the caliber and power of your Pellet gun. But Yes it is possible. In fact many pellet guns and rifles are used for rodent control.
Yes
If you are talking about a PCP (PreCharged Pneumatic) rifle. With a .45 caliber pellet, then "Yes" It can. I don't believe there is a 40 Caliber pellet gun.
Yes. Under the right circumstances.
It is possible, Yes, But it depends on the caliber, Weight of the pellet, the FPS of the gun. I suggest using a Pellet rifle not a pellet gun. I suggest a head shot using hollow point pellets. Also a license may be required to hunt the goose
Depending on where you live and the local law. Yes a pellet gun will kill a squirrel. I suggest you use "Hollow point" hunting pellets.
Yes or any small rodent.
Given the right set of circumstances, yes.
Depends on the pellet gun, the distance, and the game laws where you live. Most pellet guns should not be used to hunt anything bigger than a squirrel. They do not have enough energy for a humane kill.
