This almost exact thing happened to me in the desert. Guy was in a dry wash shooting targets he set up against a 6 foot berm created by the stream bank. Every 5th or 6th round would hit a rock and buzz past us overhead in our camp. I grabbed a rifle and slung it over my shoulder and took a circuitous route to avoid direct contact. I said hold up there hoss. People straight in front of you. He argued that the berm should stop any rounds. Shoulda woulda coulda I said. sounds like angry bees flying overhead. Please use the opposite bank or walk down the wash about 500 yds where it takes a 90 degree turn. He grumbled but went.
“took a circuitous route”
You are a wise man. lol
At one of the houses the guy set up a target out in the field without any back stop and started shooting away. Bullets were whizzing around us so we took a couple of shots with our shotguns hoping he would hear that we were out there but he didn't and kept shooting.
We got the heck out of there and stopped by his house to let him know how stupid he was.....
