See, one of the advantages that (some) humans have over animals, aside from disposable thumbs, is our capacity of higher thought. This is our ability to logically reason through problems instead of seeing everything as black and white. For instance, we are (or at least should be) able to look at GM-GUY, who has enough room on his property to build a 100 yard range, and say that as long as he has a decent berm and isn't a dick to his neighbors, it's perfectly ok for him to shoot in the back yard. In the same light, we can look at a guy with a postage stamp-size yard and deduce that he is a moron if he thinks it's safe to shoot there.Freedom is just that - as long as you are not physically harming someone else. Feelings? Cry me a river, if we have to jump through hoops over feelings then we are truly lost.
It's his property, if he wants to build a range, a three sided, 12 color shed then so be it using 1x3 strapping then so be it.
IF he harms someone or something - then deal with it. I have guns in my house, it's a fair assumption they get loaded from time to time - anyone think a 300 Weatherby Magnum with 180 grain Barnes-X bullets is going to stop in anything less than several feet of dirt? So, while loading the rifle, if I show poor muzzle discipline, and close the bolt and have a slam fire or just pull the trigger with my booger hook that round leaves my house and passes completely though the neighbors house. I'm not at my range, so does that mean no guns in residential areas either?
Back to the range - I wouldn't do it. I have a range in my back yard and intend to extend it to over 100 yards, shooting off my deck. Of course my backstop is a mountain and the target area is a pile of pine logs 6 feet thick and 12 feet wide.
How is this complicated? I'm amazed you guys don't complain about the safety rules - it's my right to sweep everyone at the range, right? Don't question my freedom unless I actually shoot someone!
