Thanks for all of your replies. Since Google, and consultating y’all failed to turn up any law against shooting after dark, I’m going to keep shooting after dusk. I never shoot past 9pm or before 9 am. I’m 300 yards through the woods to my closest neighbor. Karen can call the cops all she wants.
Up until about a year ago, I was shooting at night about once a month. Similar situation to yours, 50+ acres and neighbors are on similar agricultural/wooded properties. I always knocked off night shooting by 2200. In 26+ years on this property, never had LEOs visit unless I invited them.
As mentioned above, when hunting is gtg, so is shooting. For extended range sessions, noise ordinances can come into play anywhere, but probably not applicable to your situation and definitely not applicable to mine. The rub is, if a neighbor calls it in, LEOs are obligated to check it out. And neighbors can report practically anything; even faint suppressed reports, strange lights, voices, UFOs ...
