Possible- depending on the pellet gun. I hunt smaller animals (squirrels) with a Sheridan 5mm rifle. It WILL kill a squirrel at 45 yards. However, a squirrel and a turkey are 2 very different animals. To kill a turkey cleanly, it would have to be a head shot- and turkeys are VERY skittish animals. You also need to check if it would be LEGAL to kill a turkey with a pellet gun in YOUR state (assuming we are talking about a wild turkey) The game laws are different for each state.
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.
