I had the same problem about 15 years ago. Someone down the road was shooting and bullets occasionally bounced off my neighbor's house and mine. He found a .40 S&W bullet in his driveway.
We called BCSO and an officer stopped by to talk to us. He told us to call anytime we heard gun fire. If they had someone available, they'd come investigate and let us know the results.
Maybe a month or so later, the deputy stopped back by and told us he'd found the source and they were using an unacceptable backstop. They were required to correct the backstop. They did and it hasn't happened since. We still hear gun fire occasionally, so the shooting hasn't stopped.
Every time I've been shooting on private property where houses are within earshot, a sheriff's deputy has come by to make sure we're being safe. Our interactions have always been pleasant.
