Unless it’s a shotgun firing birdshot. This is why in many places you can hunt birds, it’s really the only type of firearm you’re allowed to use, because when shot at an upward trajectory, the pellets do not maintain enough velocity to be harmful when coming down and harmlessly fall to the ground. Anything rifled though is a different story, because its that spin on a bullet or a slug which allows the projectile to maintain its velocity and be dangerous when coming back down.
