Tell your parents. Ask them to talk to ur friend's parents. If it's at a certain place (ex:park) where you keep getting shot at and it doesn't stop, (this has happened in my city)
call the police. Don't call emergency though.
Targets on a shooting range.
Yes, although less common than firearm shooting ranges.
Yes it is illegal to shoot a bb gun in city limits. I am currently in trouble for doing this. I have to go to court and everything!!
This has a complex answer see the links below
You Don't. Shooting BB's in a pellet gun that is not designed for it will ruin the rifling in the barrel. Some airguns are designed to shoot both BB's and pellets. But if the Owners manual calls for pellets and says nothing about BB's then stick with pellets.
You need to take this question up with the child's parents.
Shooting cats is considered "Animal Abuse," So I would not suggest it.
By law BB guns are firearms in Australia. If you are 12 then you must belong to a licensed shooting club and pass a test before you can obtain a BB gun. To see more Information go to the link below.
It all depends on the country and location where you live
SOME ranges may have seperate air gun range facilities
It doesn't really matter. If you're shooting at targets or a live person, it doesn't matter. As long as it hits the target.
Have it rebuilt and new seals put in.
