Yes a C9a can be used to kill small game. The kill ratio is up to you and how good a shot you are. The best shot is a head shot with hunting pellets for a quick kill.
no it is extremely unlikely that is possible
Yes but it may be unlawful.
Because it is better not to inject air into the blood stream. enough air will kill you.
Yes, it could, or it could kill someone else.
Yes But I suggest you use a heavy hollow point pellets and the caliber be at least .20 not .177. BB's are not made for hunting.
YES! or cause other brain damage.
Yes. It has happened before.
Yes it is possible. Modern Airguns have that capability.
Yes. But you had best hit it in the head and use a heavy pellet (Pellets come in different weights). Also use hunting (Hollow point ) pellets. Be repaired to give it a second shot as the kill shot.
yes. compressed air because it has a lot of chemicals in it. But the only way this happens is if someone has a open cut or scrape on their body.
