There are no (Kept) records for this category. However the PCP (PreCharged Pneumatic) Class of air rifles will have the longest range.
350FPS would be sufficient
Yes but why would you?
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
Depending on the power of the BB gun. They will kill most any small or medium size bird. However BB guns are not designed for hunting, Pellet guns and rifles make a better choice. BB do not deform on impact and the bird will suffer before death. Hunting with a pellet rifle is more humane. Pellets (especially hollow point pellets) mushroom on impact and make a clean kill.
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. Pellet guns and rifles can be used for small game and rodents. I suggest using hunting pellets they mushroom on impact and make a clean kill, unlike BB's that don't deform on impact and may not kill the rodent or bird. The pellets will be called "Hunting or Hollowpoint."
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
