You have to be a little more precise, if you are talking about your fps (frames per second) I can help. If you are looking for what fps you are recording at on a camera or what?
yes, you should have no problem killing a bird.
25 FPS : Frames Per Second .
There is an unconfirmed report of a fast species reaching 60 cm/sec (2 fps, 1.3 mph).
Normally a 600-700 fps air rifle will kill a rabbit at around 30-40 yards away. So this will include a .22 caliber air rifle or if your looking for something with less power that will just kill birds, try looking for a .177 or .20 caliber air rifle but if you are looking to hunt game like rabbits go for .22
yes if you hit it in the brain or hit a blood vesal but other then that and at a long range you will need to use 2-3 bullets to take that lion down and it also depends on the fps (feet per secound) of the gun as well use a caliber rifle or hunting sniper not a shotgun.
