I am planning to build a tire baffle on my property, partly because of neighbors fairly close, but mostly to reduce spooking the deer - more worried about bothering the game than the neighbors, some of whom shoot more than I do.
I don't believe gunfire bothers deer vary much. I've had to hold my fire, after shooting several shots, to let browsing deer slowly make their way across my shooting range. We also have called "cease fire" at the public range to let deer pass through.
