Sure, but in private transportation. I think this is a given, but the TSA wouldn't allow it on a plane.
If you can legally possess the shotgun, transport it unloaded, locked in the trunk, and shoot in an area where legal to do so, then yes.

A shotgun can shoot up to 80 yards it it depends on what the choke is on the gun.
In most U.S. states there is no specific minimum age to shoot a shotgun (or any gun, for that matter) but there are laws regulating how old you have to be to purchase one, which is 18, at least in most states, for a shotgun.
a 12 gauge shotgun can shoot about 30 yards accuracy
No
no. Why would you?
check with your state prosecutor's office
Pellets or slugs. shotguns usually shoot shot or pellets, but you can shoot slugs. in Indiana we use a shotgun to hunt deer and use shotgun slugs, better to use a barrel with no choke in it. cylinder bore preferred.
Your best bet would be to take it to a gunsmith for a professional appraisal.
Yes, but an easier method would be to sprinkle salt onto the slugs.
aim and fire Another answer: You do not aim a shotgun, you point a shotgun. You shoot where the target will be when the shot gets there, not where the target is when you pull the trigger. That is called "windage."
