hows that? especially when according to the law, it does not meet the definition of a "firearm"?
"Firearm” means any deadly weapon capable of expelling or propelling one or more projectiles by the action of an explosive or combustible propellant. “Firearm” includes an unloaded firearm, and any firearm that is inoperable but that can readily be rendered operable.
im fairly sure there is no specific ordinance in columbus forbidding you from shooting a pneumatic or spring loaded gun.
the law does state: When determining whether a firearm is capable of expelling or propelling one (1) or more projectiles by the action of an explosive or combustible propellant, the trier of fact may rely upon circumstantial evidence, including, but not limited to, the representations and actions of the individual exercising control over the firearm
so if you try to rob a bank with it, or try to pass it off as a real rifle and wave it around or some shit, you can be held liable as if it were a real gun.
honestly, the best thing to do would be to call the CPD and ask them if its legal to shoot a bb gun in your yard or not.
