Copahee Bay and Gunfire?

I hit Copahee Bay for the first time a couple of weekends ago, had a great time on an in-coming tide. The only problem was the sound of gunfire coming from a waterfront home (my guess as to the source). Someone kicked off 30 to 40 rounds of what sounded like pistol fire into the marsh. Is this common there? If you do call it in, don’t expect the cops/911 to know where Copahee Landing is.

Thanks
