My wifes father is a big hunting gun guy. He has a sweet private range at his house for long range shooting. His house sits way above the range I would say at least 200 yards away and with a huge change in elivation since he lives on top of a mountain and the range is way in the valley below. A friend of his asked to come shoot he said "sure but I cant join Im doint some work today up at the house" Well he didnt ask what the guy was shooting. After a few rounds and every window in his house shaking like crazy and him now knowing what was going he he realized 50 cal. Now to anybody who asks can I come shoot me included he says "Sure , Just dont show up with a 50 cal ".
