Yes it is passable, so don't ever aim a BB gun at a person. Buy the way, BB guns usually don't travel at 1200 FPS Pellet guns do.
yes. It is possible but I suggest you use hunting pellets (hollow point)
With the right pellet you you can, But it should be a hunting Pellet (Hollow-point) and it should be a heavy pellet not a light weight pellet with at least 900 to1000 FPS.
See the link below for a list of UK air gun laws.
Yes it is possible
Depends on the FPS. If the gun is over 400 fps it can go threw a can. My friend has a 400 fps ak 47 and it can kill the can.
You mean Air Rifle. Yes this is fine. Air rifles (Not AirSoft) usually fire between 500 FPS and 1200 FPS
350FPS would be sufficient
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.
Depends on what you are trying to kill. A small rodent, then Yes. A larger animal then most likely NO.
In most cases it will be a BB gun. But Pellet guns exceed both the BB and the airsoft guns. Pellet guns can attain speeds over 1200 FPS.
Yes: small game. Rats, squirrels and small birds.
the most fps in a gun is 500 or more and my best gun is a mp44 because its 517 fps and it hurts and it feels like a bb gun
