CAUTION - THREAD HIJACKING IN PROGRESS (sorry, @farmer44)
@Alan, you just crystallized a thought that has been bumping around in my head for a while now. Big-bore air guns shooting true bullets totally blur the lines between PBs and air guns. Yes, the big-bores still don't have the same range as the PBs but that's just semantics. The cheap little "Saturday Night Specials" of the '70s and '80s had an effective range measured in feet, not yards, yet they were deadly and eventually outlawed. I dread the day that a story hits the online wires reporting that someone or, God forbid, a whole family is gunned down by a disgruntled ex-this-or-that using a large bore air rifle. Knowing our modern Media it'll probably end up being called a "BB gun" because that will make the story even juicier. None of this will be the fault of air gun enthusiasts who enjoy expanding the limits of air gun performance! Humanity is a broken and debased race and virtually every good intention and invention has been twisted to serve venal and evil people at some time and place. Just look at Alfred Nobel and his miraculous and time-saving invention: Dynamite! All we can do is be careful and considerate in our shooting, ready and willing to educate others about air gun fun and safety, and prepared to confront yahoos who insist on doing stupid things with air guns to our communal detriment.
