Put it this way if he wasn't in a hole I could see him when he shoots so go out and measure how far 500 ft actually is. you'll find it's not that far.

When you go the range you wear head gear or ear protection correct? And you can always tell when someone walks up with a 1911 or 50 cal once they fire that bad boy because you're like HELLO even with ear protection on. Now imagine having a 50 BMG fired only at the longest distance away possible 500 feet after you have measured to see that isn't that far... and you have no head gear or ear protection because you're just in your house minding your business, yeah it's really loud. The rapid gun fire from the fully automatic is really loud as well. Look I have a 45 I shoot and I use to think it was loud till I heard the 50 BMG, it makes the 45 sound like peeeewwwwweeeee kind of like a 22 compared to a 40 cal it's like pew pew not Bang Bang huge difference.
