Some years back, the Board of Supervisors of Prince George County, Virginia was trying to alter their ordinances on discharge and was throwing around ideas about how far from dwellings, how far from roads, how much property you have to own, etc..
At the meeting itself, we were able to convince them that arbitrary distances from this or that have no bearing whatsoever on whether the firearm is actually discharged in a safe manner, which is all anyone should really be concerned about. And since state code already criminalized reckless discharge of a firearm, there was no need for the county to make such arbitrary decisions which have the effect of limiting property rights and 2A rights.
The Board agreed and rescinded ALL ordinances relating to discharge, which now allows me to shoot (safely) on the mere one acre around my home.
Assuming there must be something in CT state code that criminalizes reckless discharge of a firearm, CT activists could make the same argument.
