While the blanks can be considered a pyrotechnic, it does not change the status of the firearm itself.

Most cities/municipal zones that have ordnances about discharging a firearm within city/municipal limits, say nothing about the type of ammunition, the act says firearms, so if one shoots a firearm, even though it is a blank round (noise maker/pyrotechnic) under the law you have still discharged the firearm.

If the need exists for scaring birds, coyotes, foxes, feral dogs the Orange plastic flare pistols have banger shells available, but then you can also run a foul of noise ordnances too and when a 110 -150 decibel bang goes off in the neighborhood, expect that someone, especially in this day and age , will be calling the police and who will respond to the the report of a sound of an explosion or shots fired.

They might tell you not to do it again or ticket you for disturbing the peace or even mischief and depending on where and who, send you the bill for the call out.

So the airhorn pots and pans or even a super soaker would be a better option in my opinion.

PS. Blanks are also not that common, they are out there, but you really have to look for them.
