Have a neighbor about 150 yards away. His land backs up to the side of my land. He is firing a weapon across the lake we share. The rounds are bouncing off the water,ice or whatever he is aiming at and hitting the trees on my land. I hear a pop but not the crack of a firearm. I think it hits the ice or whatever and then when it hits the trees 400 ft. away it sounds like an acorn hitting the hood of a car. One ricoshae actually had a distinctive whistle to it. I don't sweat bb guns but either he has a silencer or a HIGH power pellet gun and I think he can cause severe injury or worse to people or our pets. When I talked to him a few years ago. He said gee it's only a pellet gun. But some of these air guns can fire a 38cal. at close to 1000 fps.. I don't know the guy and wouldn't recognise him in the checkout line. And I don't want to get into a pissing contest with a neighbor and I'm not sure I should call the S.O. . Any suggestions?
